Equipped with a special built-in mechanism that allows you to turn each of them into a bed in a matter of seconds. The choice of this mechanism depends on the area of ​​​​the room, the frequency of use, as well as on various additional advantages (ease of layout, the presence of drawers for linen, etc.). All models can be conditionally divided according to the type of mechanism into rolling out, unfolding and unfolding. Let's take a closer look at each of them.

Sofas with folding mechanism

This is a widespread and one of the oldest mechanisms. His bed is formed thanks to the back and seat. They are stacked horizontally when transformed, forming a double bed. The most popular types are "click-clack", "eurobook", "book".

"Book"

This is a very simple layout. It is necessary to raise the seat until it clicks, then lower it, after which the back takes a horizontal position. These types of folding sofas are designed for daily use. They create a high bed, and also suggest drawers designed for bed linen. These sofas are not the most reliable, as they wear out quickly enough. To expand the "book", you will need additional space. If it is located against a wall, then it will need to be moved away. Therefore, when it is best to immediately leave a distance behind the back of the sofa, so that later, when laying out, it does not have to be “carried” around the room.

"Click Clack"

Views with the "click-clack" transformation method have the same mechanism as the "book". At the same time, there is an intermediate position of the back, which allows you to remain in the “reclining-semi-sitting” position. This gives an additional advantage and makes this piece of furniture for relaxation even more comfortable. To move to the relax position, you need to raise the seat to the 1st click. Raising it to the 2nd click, you can expand the sofa completely.

"Eurobook"

Such types of folding sofas require practically no effort during the transformation. The seat is pulled forward, while the backrest fits into the free space. They are convenient, when laying out they do not require a lot of space (they can stand against the wall). Compared with the same "book" they form a wider, even bed. They also have drawers for laundry. A feature of such sofas is that they do not have such a mechanism as the "book". Thanks to this, they practically do not break. Their only drawback is that with everyday use, the seat rollers can spoil the floor surface.

Sofas with unfolding mechanism

This is quite popular, although not the most popular. Such types of sofas suggest that the sleeping place remains inside under the seat when folded, and when transformed, it first moves forward, and then unfolds to form a bed. The most common type is a folding bed, as well as its varieties: "sedaflex", French folding bed.

french cot

This is a triple folding mechanism located under the seat cushions. Before unfolding it, it is necessary to remove the pillows, then pull out the lower part by the handle, and then gradually unfold it. His bed is a frame, which consists of three sections connected by hinges, and a mattress. These types of sofa mechanisms are widely used in models that differ in design and price. They are very small and do not affect the appearance in any way. It does not assume the daily use of furniture. Such a sofa is more suitable for guests (exceeding the permissible load and frequent use will lead to sagging of the mattress). In addition, these models do not have a place to store linen.

"Sedaflex"

Similar types of transformation of sofas resemble a French folding bed. Although they are more expensive and durable. During the layout, you need to slightly raise the mechanism, and then pull it towards you with force. This is one of the most reliable models, it is able to withstand heavy loads without changing the frame. Such designs allow you to form a rather high and wide berth, while the folded sofas are very compact. The only disadvantage of such models is the lack of storage space for linen.

Types of sofas with roll-out mechanism

This type of mechanism is becoming increasingly popular due to ease of use, high strength and spaciousness of the bed. It is very convenient to lay out such a sofa, since the berth is pulled simply forward. But when acquiring such a model, you must carefully consider all the components of the mechanism. For example, experts say that a good sofa should have closer springs, then it will last a very long time. Models with a roll-out mechanism have one characteristic drawback - a low berth that can push through and scratch the floor during transformation. Common models: "dolphin" ("kangaroo"), "accordion".

"Accordion"

Similar types of transformation of sofas are based on the “accordion” principle: in this case, the seat rises to a slight click, and the double back folded into a house stretches like an accordion, thereby forming a flat bed with a seat. Such models are very easy and quick to unfold, have covers for each of the elements and drawers for linen.

"Dolphin" ("kangaroo")

This is a mechanism that is installed more often than others in various types of corner sofas. When laying out, a platform rolls out from under the seat, which then rises, forming a flat bed with a seat. These types of sofas are very durable, they can withstand high loads, so they are considered one of the most durable. But such models cannot be called compact.

Design features

It should be noted that the shape distinguishes island, straight and corner sofas. The latter are installed in the corners of the room. They are great for small rooms. This is one of the most modern and fashionable types of upholstered furniture. As soon as the sofa is in the room, it immediately becomes much more comfortable.

One of the advantages is the ability to vary the design and shape as desired. I must say that everyone, having considered the types of corner sofas, will be able to choose the one that suits him. The sides of such models can be the same or different in length.

Island sofas are most often sold in a rounded shape, and therefore, they cannot be placed in a corner and leaned against a wall. They should occupy a central place in spacious rooms.

Appointment of sofas

Such upholstered furniture for its intended purpose is conditionally classified into the following models:

At the same time, the mechanisms and types of models may differ, therefore, it is necessary to choose a specific thing that is directly suitable for your purposes. Often it is the types of sofa upholstery that determine their purpose. For example, models sheathed in leather are designed for kitchens or offices. For children's rooms, sofas are covered with bright and practical fabrics, from which it is easy to remove stains.

Types of sofas by size

All models are divided into compact and large designs. However, there is no single standard. One manufacturer makes a two-seat sofa 1.6 m long, and the other - 1.9 m.

It is necessary that the model that you like does not occupy all the free space in the room, does not block the balcony door. Before buying, measure the area of ​​\u200b\u200byour room and compare it with the dimensions of the sofa.

We hope the tips in this article will help you make the right choice, and your sofa will serve you faithfully for many years. Good luck with your purchase!

Sofas have become such an integral part of our lives that today it is difficult to imagine a living room without this interior element. On modern models, you can not only sit comfortably while watching your favorite movie, but also sleep, play with children and just be proud of a stylish solution for your home. Beautiful sofas of various designs will help transform the look of your home and use its space wisely.

Types

The variety of sofas today is striking and somewhat disorienting to a potential buyer. It is one thing to choose a model from five options, and another from a thousand. However, here it is important to calm down and not run after the first color you like, because the main goal of the right sofa is the convenience of its owner. The comfort of the model depends on one of the key factors - the folding mechanism.

It is worth noting that not every sofa is transformed into a sleeping place and has folding properties. For example, monolithic sofas find their purpose in offices, because a sleeping place for a working room is irrelevant, and therefore there is no need to overpay for it.

Nevertheless, if upholstered furniture is selected for daily use at home, it is important to make a choice. the following layout mechanisms:

• "book";
• "Eurobook";
• "click-clack";
• "tic-tac";
• "accordion";
• "roll-out";
• "cot";
• "dolphin";
• "konrad".

"Book", "eurobook" and "click-clack" are related mechanisms. Their feature is to lift the seat and pull it towards you. The back and seat are thus reunited and represent a large bed. More modern models are equipped with a click-clack mechanism. Unlike its predecessors, it has several positions, for example, reclining, and also allows you to create an imitation of armrests.

The accordion sofa is also included in the classic and familiar mechanisms, which are also quite reliable. The backrest in the assembled state consists of 2/3 of the bed, which, when pulled out, reunites with the third part and forms a comfortable bed.

The roll-out mechanism embodies ingenious simplicity. When the seat is pulled forward, all parts of the steel seat are pulled behind it, after which one part is placed on the wooden frame. The clamshell French and American did not just deserve its name. The familiar folding bed extends from the seat and rests on strong iron legs. The disadvantage here can be considered a lower density of the bed.

In addition to comfort and convenience, some mechanisms are also preferred because of their careful attitude to floor coverings. So, not wanting to constantly correct a carpet that has moved out or scratch linoleum or laminate, you should pay attention to the mechanism "tic-tac". Its seat does not extend, but rises, which eliminates any movement of the sofa parts on the floor. At the same time, the back of the model is placed in the vacated space and becomes a spacious sleeping place.

The beautiful name of the sofa "dolphin" is also not invented just like that. When assembling the sofa, part of the bed goes under the bottom of the seat, reminiscent of the dive of this graceful inhabitant of the seas. Sofa "konrad" - one of the most beautiful and comfortable mechanisms for sleeping. Parts of his sleeping place, rolling forward, have a spring block in their arsenal, which has orthopedic support for the body during sleep.

And if everything is clear with the mechanisms, then it's time to turn to another important point of a beautiful sofa - the choice of upholstery. Sofas can be divided according to this feature into two groups:

• leather models;
• fabric.

The first option involves the use of natural and eco-leather. Their price segment is vastly different, as is the wear resistance period. Natural models will serve for many years without cracking and delighting with softness. Fabrics for upholstery of upholstered furniture in some cases have complex names, but their knowledge will help to acquire a quality model. So, the most affordable option is natural cotton, which can last about 5 years without any processing.

If the model in your dreams should have velvety and comfort, the best solution would be upholstery with flock, jacquard and chenille. If the sofa involves a complex, well-drawn print, it is best to use tapestry. Its weaving is made with a mixture of cotton, wool and synthetic threads. Arpatek is considered a luxurious innovation. This material resembles the texture of thin delicate skin, while consisting of a fabric web. The wear resistance of such models is incredibly high.

And in addition to fabrics and mechanisms, beautiful models have a different shape. For example, a corner sofa is perfect for placing a sofa in one of the corners of the room. If the sofa is located in the center, choose a classic model with armrests.

The most fashionable colors and materials

Designers this year tried to create not just beautiful sofas, but elements of comfort and warmth at home. For example, smoothness of lines has become an important feature. The colors this season are also full of warm radiance in shades of wood, sand and beige. Stylish models today include several colors and textures. So, one of the most popular is natural wood with its characteristic pattern. In this case, almost everything is suitable for fabrics, for example, a vintage-style tapestry.

In addition to fabrics, designers consider leather to be very relevant. And if for some a leather sofa is associated with an office environment, experts offer combined models.

Color range of sofas for 2017:

• red;
• white;

• graphite;
• combination.

The last point is given special attention. Light and white sofas are decorated with contrasting pillows in the color of young greenery. Bright models, on the contrary, become more subdued due to accessories of a neutral shade.

How to choose?

Before going to the store in search of the most beautiful model, it is important to decide on the purpose of its purchase. Sofas in the hallway, living room or nursery have completely different priorities in choosing, as well as purely individual sizes.

Before going to the store in search of the most beautiful model, it is important to decide on the purpose of its purchase. Sofas in the hallway, living room or nursery have completely different priorities in choosing, as well as purely individual sizes. You should start here with the living room. This room is considered the soul of an apartment or house, and the soul must be beautiful in everything. Both monolithic and folding sofas are suitable for the living room, if the living room also serves as a place for residents to sleep. So, before buying, it is important to measure the room and determine for yourself the desired size of the sofa, which will not hamper the household and interfere with free movement around the room. Today, almost every manufacturer offers to make furniture according to individual sizes, which is an indisputable advantage of modernity.

It is important to measure the vending model not only assembled, but also disassembled. For a cramped living room, compact and small sofas are a good choice. A room that is not limited by strict frames will organically accept unusual models of various shapes. And if all the parameters agree, you can proceed to the inspection. High-quality models never creak, and the mechanisms work smoothly and effortlessly. It is good if each of the household can easily assemble and unfold the sofa. Convenient for all details will prevent breakage from incorrect and inaccurate layout. In the unfolded state, the entire structure should be as stable as possible.

And also soft creators of comfort can be successfully located in the hallway, because sometimes after a hard day's work you really want to sit down on something comfortable without taking off your shoes. A small sofa will perform this task as well as possible and will not take up much space, contrary to stereotypes.

Modern models for the hallway are performed:

• in the form of soft banquettes without a back on carved legs;
• small sofas with a backrest without armrests;
• sofas with back with metal forged and wooden armrests;
• in the form of a sofa with a folding bed;
• in the form of an angle sofa
• narrow sofa with practical drawers under the seat.

When choosing, you should focus on the shape and size of the hallway. A narrow and small rectangular hallway can only accommodate a bench. It is not recommended to load it with lockers and other details. Simple models in this case look more harmonious and lighter. The square entrance hall is made cozier by the corner model of the sofa and even the model with armrests. If this part of the apartment or house pleases with spaciousness, then a full-fledged sofa will turn the hallway into another place to relax.

But for a children's room, an important criterion, first of all, is safety. It shows up in everything. Environmentally friendly materials such as wood, rounded edges and a minimum of synthetics in fabrics will be the key to a successful purchase.

How to care?

When a sofa is bought and pleases the eye, you should not relax, because care is another key point in the long-term operation of furniture. So, fabric upholstery is cleaned with a soft brush or vacuum cleaner every three days. This action allows you to remove daily dust, preventing its deep penetration into the fibers.

If visible contamination nevertheless appears, you should turn to specialized products for cleaning the upholstery, remembering the general rules for all types of fabric:

• all pollution are removed in the direction of the pile;
• spilled liquid it is absorbed with a soft cloth, without rubbing the wet spot;
• stain being processed from edge to middle.

Treating leather and keeping it looking presentable is no easy task. First of all, a leather sofa should not be closer to the batteries by more than a meter. This will prevent cracking of the skin. And on the leather model, it is not recommended to put your favorite colored rugs and capes, thereby preventing skin staining. Once every few days, such furniture is wiped with a dry soft cloth.

It is worth noting the need for wet cleaning with microfiber once a month. Visible dirt can be removed with soapy water. After the procedure, the surface is wiped dry. If the spots are difficult to remove, the most reasonable solution would be to use special products for the skin.

When buying a sofa for home or summer cottage, special attention should be paid to the device of its transformation. The organization of the sleeping space and the durability of the model depend on it. Today, the mechanisms for transforming sofas are very diverse. They are designed taking into account the area of ​​\u200b\u200bthe premises, often they easily turn a sofa into a bed. Even a teenager can handle them. In order not to get confused when choosing, you need to know the principle of operation, the features of each device and the degree of load on the furniture frame.

Types of sofa mechanisms by type of transformation

Three types of sofas can be distinguished, in which special transformation mechanisms are used. They may be located:

• In direct models- representing a familiar design from the main part with or without armrests, having a linen box (and in some versions - a box in which the sleeping block is located).

• In corner structures- with a corner element that has its own functionality in the form of a niche, a spacious box for bed linen or other things. It saves space in your closet.

• In island (modular) systems - structures consisting of separate modules, different in area, but the same in height (depending on their number, they change their functions).

The sofa owes its name to the mechanism of transformation. Although companies come up with an interesting name for each model, the basis of the name that characterizes a particular model is precisely the principle of its mechanism.

The operation of the device does not change - regardless of the type of model (straight, modular or angular). The sofa unfolds forward, sometimes at the same time it rises up, rolls out, extends, turns. If this is a straight view, the base is transformed, in the corner version the sleeping block is added to the corner, forming a rectangular seating area. In modular constructions, the direct part of one module is transformed without affecting others.

The work of any mechanism is not as complicated as it might seem at first glance. The principle of operation of structures is different and has both pluses and minuses. Most of them can fit all types of sofas (straight, corner, modular). For them, the presence or absence of armrests of the model does not matter. However, there are transformation systems that fit only one species.

Sliding and withdrawable

Roll-out forward models are convenient, they are compact when folded, do not take up much space, do not create the impression of a cluttered room. The principle of their work is to roll out the block forward and raise it to the desired height. Sliding structures are models whose details are interdependent, so when transforming one, the other is automatically activated.

"Dolphin"

One of the universal models with a fixed back and a simple transformation device that allows you to place the sofa in the center of the room or close to the wall.

To unfold the model, you need to pull the loop of the box located under the seat, in which the missing section of the bed is located. When the block is extended to the stop, it is lifted by the loop, put in the desired position at the level of the seat. This design forms a spacious and comfortable surface for sleeping, withstands a large weight load.

"Venice"

The principle of operation of the roll-out mechanism resembles the Dolphin. First you need to push the section located under the sofa seat all the way towards you. By driving the transformation device, extend the seat unit, increasing the width of the sleeping bed. After rolling out the block to the stop, it is raised to the height of the seat with the help of loops.

Such designs are convenient. They are often found in corner models, have a lot of free space in the corner elements.

"Eurobook"

An improved "book" is a great option for daily use. It is equipped with a reliable and easy-to-use transformation mechanism that is resistant to daily stress and allows you to place the sofa in the center of the room or against the wall.

To carry out the transformation, you need to take hold of the seat, lift it slightly, pull it forward and lower it to the floor. Then lower the back, forming a sleeping place. Such furniture rarely has a spacious sleeping bed: it is compact both when folded and disassembled.

"Conrad"

The device, which some manufacturers call "Telescope" or "Telescopic", is a withdrawable model. To make a bed out of such a sofa, you need to pull out the section under the seat, raise the base, then put the pillows in the drawer, close the base and place the mats on it, unfolding them like a book.

The design is convenient and allows you to organize a spacious bed without moving the sofa away from the wall. The floor surface must be flat, as for all withdrawable mechanisms, therefore, a carpet laid on the floor may cause the transformation system to fail.

"Pantograph"

The design, known as "tic-tac" - a variant with a walking mechanism. It is an improved version of the Eurobook. For transformation, you need to pull the seat forward with the help of loops, lifting it up. At the same time, it will itself take the necessary position, dropping down. It remains to lower the back, forming a spacious sleeping place for two.

In some models, the manufacturer has provided additional armrests that limit the seating area. Such a device is durable and does not loosen the body of the model. However, options with a soft back are not very comfortable. To expand such a sofa, it will have to be slightly moved away from the wall.

"Puma"

This model is a kind of "pantograph" - with a slight difference. As a rule, these sofas have a low and fixed back, so these models can be placed against the wall, thereby saving usable floor space.

The transformation is carried out by one extension of the seat - unlike the previous mechanism. When it rises and, falling, falls into place, at the same time, the second block of the sleeping section rises from below (where the seat used to be). Once the seat is in place, the two blocks form a complete sleeping bed.

"Saber"

Convenient roll-out mechanism "saber" provides for changing the size of the sleeping bed with full or partial unfolding. This design is distinguished by a linen box, a high place to sleep.

Sleeper furniture can consist of two or three sections - depending on the model. To expand it, in any case, you need to roll out the seat, under which the linen box is located, forward. At the same time, the backrest leans back, fitting into the desired position.

"Goose"

The original roll-out transformation system, for which you must first roll out the bed block from under the seat, and then raise it to the level of the seat. At the same time, due to the peculiarities of the pillows rising on the back of the structure, there is an increase in the sleeping bed.

Assembly and disassembly of such structures take more time than other systems.

Such a model is quite complex and not suitable for daily use. But when folded, models with this system are very compact, they look neat, so they can be purchased as upholstered furniture for a summer residence or a living room.

"Butterfly"

Sofas-transformers with the "butterfly" system are considered one of the most reliable, durable and durable. Today, such a system is very popular among buyers. She turns a sofa into a bed in just a few seconds. The transformation is carried out in two stages: the seat is rolled out forward, then the upper block is folded back (to the extended rear section).

The advantage of the model is the significant size of the sleeping bed in the unfolded form and compact assembly. The disadvantage of the mechanism is the vulnerability of the rollers during transformation, as well as the small height of the sleeping bed.

"Kangaroo"

The kangaroo transformation mechanism resembles the dolphin system - with a slight difference: abrupt movements similar to kangaroo jumps. It has a lower part, located under the seat, which, when unfolded, easily slides forward. The retractable block rises to the right place, firmly in contact with the main mats.

The main thing that distinguishes such a mechanism is the presence of high metal or wooden legs. The disadvantages of the system include a short service life with frequent transformation. This design cannot be called reliable.

"Hesse"

The device of this mechanism resembles the "dolphin" system. To expand such a sofa, you will first need to pull the loop of the lower section under the seat, pull it out until it stops. The seat will also roll out. Then the block is raised to the level of the height of the berth, the seat mat is lowered back, forming a full-fledged sleeping bed in three parts.

This system is used in straight and corner sofa models. However, it also has its drawbacks, because with the constant rolling out of the block, a large load is created on the frame of the sofa. In addition, if you do not take care of the rollers, the mechanism will have to be repaired after a while.

folding

Mechanisms with unfolding sections are no more complicated than roll-out ones. Usually they are based on the most versatile systems (“frog”), so they do not require more than a few seconds to turn the sofa into a full-fledged bed. For their transformation, it is not necessary to roll out sections from under the seat.

"Click Clack"

The design of such a mechanism has a second name - "Tango". Some manufacturers call it "Finnish". This is a bifold model, an improved version of the classic "book".

To expand the sofa, you need to raise the seat until it clicks. At the same time, the back is lowered back, the seat is slightly pushed forward, revealing the two halves of the block into a single surface for sleeping.

"Book"

The simplest transformation mechanism, reminiscent of opening a book. To make the sofa look like a bed, you need to raise the seat, lowering the back. When the back begins to fall, the seat is pushed forward.

"Scissors"

The corner sofa transformation mechanism, the principle of which is to rotate one section to another - with the unfolding of blocks and reliable fixation of the sections with a metal fastener from below. In this case, a compact sleeping bed is formed with a bedside cabinet, open as a result of the transformation of the sections.

"Caravan"

The design, the unfolding of which is similar to the Eurobook system, however, it has a fixed back, and instead of two sections of the sleeping bed, three are laid out. At the same time, the seat is also raised and simultaneously pulled forward, then lowered to the desired position on the floor. At this time, the next one moves out from under each block, folding together into a single area for sleeping. Comfortable design with a spacious seating area. In some designs, instead of the third section, a folding pillow is used, which stands in front of a fixed back.

Daytona

System with folding fixed cushions that act as a backrest. The device of the mechanism is a bit like a "clamshell". To transform the sofa into a bed, you need to raise the pillows to the top position, then put the lower ones in the allotted places, grab the handle and turn the seat unit down, revealing a two- or three-piece sleeping bed. When the sleeping place decomposes, you will need to lower the pillows, wrapping them on the bed.

"Tornado"

Folding mechanism designed for daily use. The design is based on a double-folding "folding bed", which is hidden in the usual position of the sofa. It transforms without removing the seat, after tilting the back of the model. The design is convenient, it is not very difficult to disassemble, it has steel elements and mesh at the base, as well as mats of moderate rigidity.

deployable

The following devices provide transformation by deploying sections. In most models (with the exception of the "accordion"), the back is fixed and does not participate in the disassembly of the sofa.

"Accordion"

The device of the mechanism, reminiscent of stretching accordion furs. To expand such a sofa, you just need to pull the seat. At the same time, the backrest, consisting of two blocks connected from above, will automatically fall down, unfolding into two halves.

"Belgian cot"

This design is like a "cot" hidden under the sofa's modular seat mats. Even outwardly, the system resembles a familiar piece of furniture with metal supports. The only thing that makes it different is that it is fixed at the base of the sofa and unfolds right out of it, turning the seat unit down

"French cot"

An alternative to the "accordion" system - with the difference that in the latter the bed is made up of three blocks (according to the principle of folding a fan), and in this system the blocks are wrapped inward and unfold when unfolded. They are equipped with stands and have a narrow type of packing, which is a disadvantage of such designs.

If you are going to expand the sofa, you need to remove the modular pillows from the seat.

"American cot" ("Sedaflex")

Such a mechanism is more reliable than its French counterpart. It is not necessary to remove the cushions from the seat before transformation. The system implies identical sections (there are three of them), which are laid out one after another when the seat is raised. Such a mechanism is quite durable, but it is only suitable as a guest option, because it has thin mattresses, there is no compartment for linen, and steel structural elements are felt at the joints of the sections.

"Spartacus"

A variant with a clamshell mechanism. The folding structure is located under the seat, consisting of modular cushions. In order for the sofa to become a bed, you need to remove the pillows, freeing the clamshell blocks. Since they are in the wrapped position, they first take the top one, set the desired position by exposing the metal support, and then unfold the remaining sections. This design is not designed for daily transformation - like analogues.

with swivel mechanism

Models with a rotary mechanism differ from other systems in ease of transformation. In them, the load on the frame is minimal, since there is no need to roll out the sections to the stop. They do not need to lift additional blocks.

Both the integral part of the sofa and the component of each block can turn, depending on the model. Such a mechanism is used in corner models, connecting the two halves of the sections with blocks into a single bed. The principle of operation of the system is based on turning half of the block by 90 degrees and rolling it to the other part of the sofa (with subsequent fixation).

With folding armrests

Folding armrests - a unique technique of the transformation mechanism. Today, such sofas are in the center of attention of designers. With their help, you can furnish the children's room, if necessary, adjusting the dimensions of the furniture.

"Lit"

A peculiar design that allows you to change the size of the sleeping bed due to the deformation of the armrests. At the same time, the sidewalls themselves can be positioned at any angle - and even the positions can be different. To transform the sofa into a single bed, you must first lift the armrest inward until it stops, and then bend it outward. These designs are designed for direct varieties of sofas, they are bought for children and teenagers.

"Elf"

A system convenient for small-sized rooms and children's rooms, a large area for transformation is not needed. Furniture can be placed against the wall. This sofa can be compared with its counterpart, it has a compact body and ample space for storing bedding. The seat surface and armrests form a single unit that folds out in length.

With advertisers

Such devices of the mechanism are somewhat more complicated than the others. Moreover, the design of the mechanism allows you to easily change the position of the angle of inclination of the backrest and footrest, creating the most comfortable position for the user. This sofa can be equipped with a massage mechanism, it has a rather solid appearance, but the transformation into a bed is not carried out.

Double and triple folding systems

The mechanisms of transformation may vary. As a rule, the more complex the mechanism, the more components of the bed (the number of additions). Folding and pull-out sofas fall into this category.

Which one is better for daily sleep?

When choosing a sofa for daily use, you need to pay attention to designs in which the load on the frame during the operation of the mechanism is most uniform and does not loosen the body.

It is necessary to choose the right not only the mechanism, but also the degree of rigidity of the backrest, seat. You also need to choose a good upholstery material and pay attention to models with the ability to change covers.

Filling blocks

When choosing a sofa for daily sleep, it is worth considering the block filler. It is of two types: spring and springless.

The first packing options are distinguished by the presence of twisted springs (the position is vertical). We can distinguish between dependent and independent types. In the first case, the sofa bends down. Such mats are unreliable in that they do not have proper support for the spine during rest or sleep (sitting and lying down).

Independent type springs do not touch each other, so each of them works independently, without forcing the others to sag where they do not need to. As a result, the back always remains flat, and the load on the spine is reduced.

Springless mats have a remarkable orthopedic effect, it is the prevention of problems associated with the spine. They are not only safe, but also very comfortable, provide a complete and proper rest during sleep.

This type of filler is hypoallergenic, this stuffing is not subject to the formation of fungus, mold. It is resistant to dust accumulation, because there are no significant voids. The best springless fillers include natural or artificial latex, coir (coconut fiber), PPU type HR.

What's better?

In order for the sofa to serve for a long time, it is better to choose a quality type of filler: a block with independent springs, latex or coir. It is very good if the type of mat is combined - when not only the core of the stuffing is added, but also other material (to give the desired rigidity).

If a latex block doesn't fit the budget, look into HR-type furniture polyurethane foam or synthetic latex. These materials are somewhat inferior to expensive packings, but with proper operation they will last for 10-12 years.

As for the transformation mechanism, “dolphin” designs and their analogues, models with a “clamshell” system, are not suitable for daily use. The most reliable designs for every day are "Eurobook", "Pantograph", "Puma" and rotary mechanisms.

How to choose the right mechanism?

It is impossible to single out one mechanism unambiguously. The choice depends on several factors:

• designated space for the sofa (folded and disassembled);
• the purpose of the sofa (guest option or alternative to the bed);
• load intensity mode (weight control, taking into account the choice of the “correct” seat and back blocks);
• simplicity and ease of use (the sofa should be light, because complex systems break down more often and cannot always be restored);
• the correct diameter of the steel elements (at least 1.5 cm).

In order for the purchase to be successful, the sofa lasted for a long time, you should pay attention to:

• flawless course of the mechanism in operation (it should not jam);
• lack of looseness of the structure during transformation (this is an obvious marriage that reduces the life of the sofa);
• absence of rust, scratches, dents, mechanism assembly defects;
• high-quality upholstery material that will not wear off from the frequent transformation of the sofa (when sections come into contact);
• strong and durable metal of the mechanism, resistant to heavy weight loads (two or three people);
• the reliability of the frame components to which the transformation mechanism is attached.

It is important to choose the mechanism in which there is no complex design. It will be less prone to breakage.

Mechanisms for transforming sofas - briefly about each

First, let's define what a sofa transformation mechanism is. Another name is often used - the sofa folding mechanism. Professionals prefer the concept of transformation, so I will use it further.

Under these names lies an element that transforms the sofa into various shapes and positions. For example, a sofa from a sitting position turns into a sofa bed or into a sofa for "relaxation" with a partially reclined back. Another example of transformation is changing the shape of a sofa. For example, a corner sofa can be turned into a straight sofa or vice versa.

Why is it important to choose the right sofa transformation mechanism?

• The mechanism is one of the main ones, therefore the overall service life of the transformer sofa also depends on its reliability.
• The mechanism affects the convenience and ease of converting the sofa into various positions.
• Depending on the transformation mechanism, different free spaces in the room will be required to bring the sofa into the desired positions.
• Depends on the type of transformation mechanism and . After all, it is under it that the mechanism is hidden from our eyes.

Sofas without transformation mechanisms

Such sofas, by definition, do not contain transformational elements and are not able to unfold. Sofas without mechanisms are used to create seating for two or more people. You can offer this option for a small size. Less often they can be found as a sofa for sleeping. Although for people without excess weight, the use of a sofa in this capacity is quite acceptable.

Non-folding sofas can be used as separate sofa modules. By applying several similar modules, especially of different sizes, you can change the shape of a sofa made up of modules.

Monolithic sofa suitable for hallway, for the living room and decorate the kitchen or dining room. Often this type of sofa can be found in public places.

Pros: there is no mechanism, which means there is nothing to break. The service life of monolithic sofas is longer than the service life of folding sofas.

Minuses: no mechanism, no possibility of transforming the sofa. Monolithic sofas are not suitable for organizing sleeping places, especially if you need to put two or more people.

The mechanism of transformation of the sofa "Book"

Sofa "Book" is laid out in two positions: a sitting sofa and a sofa for sleeping.

The sofa is converted into a sleeping position by tilting the back of the sofa back.

During unfolding, you don’t have to move the sofa away from the wall, but keep in mind that the design of the sofa requires free space between the wall and the back of the sofa.

The folding parts of the sofa are wooden or metal frames with spring blocks attached to them. In addition to the spring blocks, another filler can be used - foam rubber or latex. A sofa with a spring block is preferable, as it has the best performance in terms of service life and comfort.

Sofa "Book" often contains a section for bedding inside

Advantages: durable, reliable, time-tested mechanism. Suitable for frequent use and organizing a bed.

Flaws: the sofa can only be unfolded in two positions - sitting and lying down. During transformation, in the part where the folding parts of the sofa are connected, a bulge or indentation may appear, which will negatively affect the comfort of sleep. The “book” cannot be placed tightly against the wall, since the unfolding mechanism requires free space between the wall and the back.

The mechanism of transformation of the sofa "Tango"

When preparing this article, I came across the fact that manufacturers invent their own names for mechanisms of the same type in terms of properties. Because of this, confusion occurs. So is the case with the Tango mechanism.

The click-clack (clack) mechanism has similar properties. In fact, both mechanisms are similar to the "Books" already described above.

The main difference from the "Book" consists in the possibility of "Tango" ("Click-clack (clack)") to take intermediate positions of the back of the sofa when unfolding.

The back, in addition to full horizontal unfolding, can be in a reclining, half-sitting position. This feature creates additional convenience for relaxation.

Sofas "Tango" have a section for storing the bed

Advantages: the mechanism allows you to fix the back of the sofa in several positions, sofas "Tango" are small in size, when unfolded into a plane, the sofa creates a surface without bumps and bumps.

Flaws: there is no way to put the sofa tightly against the wall; when transforming the back, you need a place for unfolding.

The mechanism of transformation of the sofa "Eurobook"

The work of the mechanism: the sofa seat is pushed forward on roll-out rollers, a niche is formed in shape and size identical to the back cushions of the sofa. Pillows fit into a niche, resulting in a flat surface of the bed.

Advantages: ease of converting the sofa into a bed, the simplicity of the mechanism itself - read its high reliability, large and flat place to sleep, large niches inside the sofa for storage and bed.
Flaws because of the wide seats, it is not convenient to sit on the sofa leaning against its back, especially for people with short stature.

Sofa transformation mechanism "Pantograph" ("Tick-tock", "Puma", "Walking Eurobook")

With the "Pantograph" the same story as with the "Tango" sofas. Apparently, for the sake of a red word, sellers and manufacturers have come up with a number of bright names for essentially the same mechanism. So, what else did I manage to meet under the mask of "Pantograph" - "Tick-tock", "Puma" and even "Walking Eurobook". In order not to get confused, I will continue to call the mechanism "Pantograph" (sounds somehow solid and mysterious))) .

"Pantograph" originated as a variant of the "Eurobook" mechanism. The difference is that there are no roll-out rollers in the "pantograph". Otherwise, it has parameters similar to the "Eurobook". Equipped with internal storage niches, it has a large and even bed.

The principle of operation of the mechanism: For unfolding, it is enough to pull up the sofa seat by holding its edge in the middle. Often sofas are equipped with loops - handles for easy unfolding. By pulling up the seat of the sofa, you activate its mechanism, which pushes the seat up and forward and at the same time opens the legs of the support and stands on them. The pillow back is placed in the formed niche. The result is a flat, without visible joints, a place for two people to sleep.

Advantages: sofas with "Pantograph" have a comfortable place to sleep. The mechanism is easily laid out. Such a sofa will not spoil your flooring, because when unfolding the sofa parts do not ride on the floor.

Flaws: the mechanism is expensive because of this, and the cost of the sofa becomes higher. Due to the wide seat, sitting on the sofa is not comfortable, you need to use additional pillows

The mechanism of transformation of the sofa "French folding bed"

The principle of the mechanism: The sleeping surface of the sofa consists of three sections. You need to pull the edge of the seat and stretch them forward. Sections will open and stand on legs - supports. When folding, the sections hide inside the sofa body.

Sofas of this series are not suitable for frequent use because the mechanism is rather weak to wear.

These sofas do not have a place to store the bed - the entire interior space of the sofa is occupied by a folded bed.

When assembled, the "French folding bed" is small in size, but for unfolding it will require free space (at least 1.50 meters) in front of the front of the sofa

Advantages: in the assembled state it has small dimensions.

Flaws: uncomfortable sleeping surface, no bed storage, short service life (about five years)

Conclusion: you can use the "French folding bed" to organize seating and for rare use as a bed - the option of unexpected guests lingering and staying (they won't sleep on such a sofa for a long time and will soon run away))).

Sofa transformation mechanism American folding bed (Sedaflex, Sedaflex)

The principle of the mechanism: The place to sleep has three parts-sections. You need to pull the seat of the sofa, as a result of which the sections of the bed will open and stand on supports. Unfolding takes place in two steps - first one section will open, and then the next one.

In fact, this mechanism is identical to the "French Clamshell" mechanism.

Reliability is its main difference..

The frame of the sofa and the mechanism itself are made of wear-resistant materials. This makes it possible to regularly use "Sedaflex" as a transformable sleeping bed.

Advantages: easy to operate, has good performance of reliability and durability.

Flaws: there is no place for linen, the surface of the bed has seams.

The mechanism of transformation of the sofa "Italian folding bed

This transformation mechanism belongs to the double folding mechanisms as well as the American clamshell. The double folding mechanism is a mechanism that is brought into working position in two steps.

The principle of operation of the mechanism

To unfold the Italian folding bed from the sofa to the bed, you need to pull the upper part of the back of the sofa towards you (usually the back has a special loop for this purpose).

• At the first step of unfolding the back of the sofa, together with the pillows, leans forward and then lies down and rests on the seat of the sofa.
• At the second stage the inner part of the sofa design makes a turn around its axis, this is reminiscent of unwinding a mattress rolled into a roll. After this turn, the support legs open, which were previously hidden and folded inside the structure and the formed sleeping place of the sofa rests on them.

Due to the reinforced springs, the mechanism can be folded and unfolded without significant effort.

Advantages of the Italian folding bed: this mechanism is the most reliable and durable of folding beds, it became possible due to the use of reinforced metal pipes in the frame of the mechanism, the sofa in the folded state has a compact size, when unfolding there is no need to remove the pillows from the seat of the sofa, Italian folding beds among other folding beds have the thickest and most comfortable a mattress for sleeping, in addition, lamellas and belts are used in the frame, which create an orthopedic effect.

Flaws lack of storage space for linen, high price

The mechanism of transformation of the sofa "Accordion"

The principle of operation of the mechanism: "Accordion" got its name for its similarity to the principle of operation of accordion bellows (stretch back and forth). The sleeping space of the sofa also stretches forward, as it were, while bringing the sofa to the sleeping position, and rests on the extended supports. After the transformation, we have an even, although with minor seams a spacious place to relax and sleep.

The convenience of the "Accordion" sofa in its compact size when folded. But we must not forget that to unfold the sofa you will need free space in front of its front part (you need at least 1.50 meters)

Models "Accordion" are often equipped with an additional cabinet for storing bedding. Such a cabinet is located near the back of the sofa.

There is no storage space inside the sofa itself, the space is occupied by a folded sofa.

Advantages: Reliable and load-resistant mechanism that increases the life of the sofa. Supplied with additional cabinets for storage. Ease of bringing the sofa to the sleeping position.

Flaws: the sofa, when brought into the sleeping position, rides on the floor, so it can damage the flooring.

The mechanism of transformation of the sofa "Spartacus"

The principle of the mechanism: Triple folding mechanism. It is necessary to pull the seat of the sofa and it will decompose in three steps while standing on extended legs.

The design of the mechanism was developed by Italian engineers. This mechanism belongs to the metal-frame mechanism. The frame is made of shaped pipes on which a dense mesh made of metal rods 4 mm thick is mounted. The frame consists of three sections. The mesh creates a good orthopedic effect. On top of the mesh is a polyurethane foam mattress. It is comfortable to sleep on such sofas. The design of the mechanism provides a large bed in length, which is especially important for tall people. The mechanism is very reliable because it does not contain wooden and plastic parts.

Advantages: reliability and durability, easy to unfold, can be used daily, flat and large bed
Flaws: there is no place to store bedding, since the mechanism occupies the entire interior space of the sofa when assembled, you need to remove the sofa cushions before unfolding.

Sofa with unfolding on the floor

The principle of operation of the mechanism The sleeping place consists of two sections. When folded, the sections are hidden inside the sofa body. To unfold the sofa, pull up on the inner edge of the sofa seat. Then pull the sections forward towards you. The berth has no supports and unfolds directly on the floor.

It cannot be said that the sofa is comfortable for sleeping, since the joints of the sections are noticeable and the bed itself is located very low. Therefore, such models can be used for occasional use as a bedroom. But for sitting it is quite an acceptable option.

Advantages: compact dimensions in the assembled state, the cheapest type of folding sofas.
Flaws: not comfortable to sleep, no storage space for bedding

The principle of the mechanism: The sleeping place consists of two segments. In the assembled state, the segments are in the sofa body. To unfold the sofa, you need to pull the bottom of the front. After that, it will roll forward into the working position. All that remains is to fold the pillow into the vacant seat. As a result of the transformation, a comfortable place to sleep is formed.

Roll-out sofas are durable and reliable models. Well suited for frequent use. Contain internal space for storage of bed linen.

Advantages: the most reliable, have a comfortable place to sleep and compact dimensions when assembled.

Flaws: roll-out sofa rollers can ruin the flooring when unfolding, the bed has a low height

Sofa folding mechanism "Konrad" ("Telescope")

The principle of operation of the mechanism: "Konrad" consists of three sections. To unfold the sofa, you need to pull the lower part of the sofa from the front. In this case, the sections roll out one after the other. Because of this feature, the mechanism was nicknamed the "Telescope". Sections roll out and stand on supports.

"Conrad" is a subspecies of a roll-out sofa. The main difference is the large height of the bed.

Advantages: reliable mechanism suitable for daily use, sofas have a compact volume, equipped with a box for linen, comfortable for sleeping

Flaws: mechanism and sofa are heavy

The mechanism of transformation of the sofa "Dolphin"

The principle of the mechanism: To unfold the sofa, pull the front of the sofa from below. As a result of this, a section hidden inside the sofa body will roll out onto you. Inside the roll-out section there is a pillow with a strap. You need to grab the strap to pull the pillow up. She will "emerge" and stand on the same level with the cushion-seat of the sofa. Voila, the sleeping place is ready.

The Dolphin mechanism is mainly used in the construction of corner sofas. Places for storing the bed are not located in the roll-out part of the corner sofa. The mechanism exerts a significant load on the sofa body, so when buying, pay attention to the material of the body. Knots are not allowed if wood is used.

Advantages: ease of unfolding, the optimal height of the bed.

Flaws: not durable.

The mechanism of transformation of the sofa "Elf"

The principle of the mechanism: The mechanism unfolds easily. Armrests are bred on the sides and a berth is formed.

"Elf" refers to metal-frame mechanisms. The frame is made of metal profiled pipes. Wooden slats. Armrests are adjustable in height and have several positions. This feature allows you to create the most comfortable position of the armrests for the reclining position.

Advantages: compact model of sofas, a good flat bed, slats give a good orthopedic effect, adjustable armrests, you can create a sofa for yourself.

Flaws: you can not put the sofa close to the wall, the bed is in the same place as the seat.

Sofa transformation mechanism "Recliner"

"Recliner" got its name from the English word recline - reclining or leaning back

The principle of the mechanism: The sofa transformation is controlled by complex mechanisms hidden in the sofa body. With their help, you can adjust the inclination of the back of the sofa and extend the footrest to a predetermined distance and at a certain angle.

Some models have vibration massagers built into the sofa cushions. Particularly advanced sofas have built-in electric motors that control the transformation of the sofa using a remote control.

There are models with "memory" that can adjust and remember the settings of the mechanism made directly for your body.

Advantages: very easy to manage, have fine settings - you can create a sofa for yourself.

Flaws: high price, used only as a place to relax, as there is no place to sleep

General conclusions

• Pay close attention to the mechanism when buying a sofa. The ease of use and life of the sofa will depend on choosing the right mechanism.
• Match your needs with its capabilities. How often will you lay out the sofa, what space do you have allocated for installing the sofa, especially when unfolded.
• Do not take a sofa with a obviously inappropriate mechanism just because the color is cool or because the neighbors have one. Choose individually for your needs.

Sofa transformation mechanisms - video review

For greater clarity, I also want to offer a video plot that describes the mechanisms of sofas. True, they have already been discussed above. But, as they taught at school - "Repetition is the mother of learning)))", and this video will facilitate and consolidate your understanding of the topic.

Now you know everything you need to make an informed choice about the mechanisms for transforming sofas. I hope it was helpful.

A folding beautiful sofa is not just a piece of furniture in the living room. This is a multifunctional device that allows you to solve various problems and compensate for the lack of space in the room. But how many realize that choosing a sofa is far from being such an easy step as it seems?

Healthy sleep is an integral part of a person's life, in which he spends about a third of his time. That is why a person's sleeping place should fully meet his needs and requirements, be as comfortable and reliable as possible. Unfortunately, it is not always possible to buy a high-quality soft bed. The main reason for this is the lack of free space in the room. Often in a one-room apartment there is nowhere to put a chair - not like a bed. Yes, and look in the common room-living room bed would be inappropriate. But the sofa, like any beautiful upholstered furniture, is an indispensable element of the interior of such a room. From here, the conclusion suggests itself: we need a sofa that will be part of the decor of the living room during the day, a meeting place and pastime for the family, and at night it will turn into a comfortable place to relax. And there is only one option - a folding sofa.

But here the question immediately arises: how to choose a sofa in your apartment so that it fits well into the interior and reliably serves for many years without turning into an instrument of nighttime torture. After all, as we remember, it will have to be laid out and folded at least twice a day. In other words, you need to find out which mechanisms have proven to be the most reliable, and which, on the contrary, are unsuitable for frequent unfolding. And what are the general advantages and disadvantages of sofas of one type or another? To date, the furniture range is represented by a huge selection of sofas with a variety of types of transformation. And each model has its pros and cons.

Let's consider them all.

1. Elf is the simplest and most unpretentious type of sofa.

   
   

   It unfolds by simply lowering the sidewalls-armrests, which can be fixed in a comfortable lying position. This opportunity to sit in a reclining position creates an orthopedic effect. This sofa is very compact, although it is designed for only one person. In addition to this, it has a box for bedding.

2. Sofa book is clear from the name that this view is transformed by analogy with the opening of the book.

   
   

   To turn it into a place to relax, you need to raise the seat. The back will go down, taking a horizontal position. Then the seat is lowered back. Transformation mechanisms of this type are considered the most enduring of all existing ones. In addition, these models have a drawer for bedding at the bottom. But they also have certain disadvantages. Due to the peculiarities of the transformation, they cannot be moved close to the wall. In addition, when unfolded, they are not very spacious. But the most unpleasant thing is that in the place where the back and seat are joined, a gap forms over time, which interferes with comfortable sleep.

3. Eurobook sofa. Despite the similarity in name with the previous type, this model is laid out differently. The seat slides out or rolls forward, and the soft backrest overturns into the vacant space.

   
   

   The result is a very spacious seating area with a box for bedding below. Features of the design allow you to tightly push it to the wall. And the simplicity of the mechanism makes it more durable than the model of the previous type. However, when folded, such sofas are uncomfortable: their seat is too wide, so leaning back is not very comfortable.

4. Sofa with Tango mechanism (click-clack)

   Tango (click-clack) is a stylish sofa, which is an improved version of the "book".

   
   

   It unfolds according to the same principle: the seat rises, lowering the back, and then falls back. A notable feature of this type is the convenient folding sidewalls, which can be lowered to increase the area of ​​​​the bed or raised to make armrests. Another feature of this sofa is the ability to transform the back into a semi-unfolded state. Despite the apparent complexity, the mechanism of this sofa is also durable. Plus, there is a storage compartment at the bottom. However, like the "book", it cannot be moved close to the wall.

5. Pantograph - this type of sofa unfolds according to a principle similar to the "Eurobook", except that in order to extend the seat it must be lifted up and then moved forward.

   
   

   After that, the backrest also overturns into the vacant seat. Thanks to this design, it retains its advantages in surface area, however, when folded, it is still not very convenient on it. Such a mechanism, although it provides ease of transformation, as well as an absolutely flat surface of the place to rest, significantly increases the cost of the model. But there is a box for bedding.

6. Puma - similar to the previous type of mechanism, this one unfolds according to the principle of raising and extending the seat of the sofa.

   
   

   At the same time, a soft platform rises to the vacated space from below, creating a single place for sleeping and relaxing. Such models are advantageous for easy unfolding, but, as a rule, they do not have a box for bedding. In addition, the backs of such models are separate pillows, which, in the mode of a place to sleep, always have nowhere to put them. Most often, this type of mechanism is on corner sofas.

7. The accordion is perhaps the most versatile model. It unfolds according to the “accordion” principle by extending the seat, which drags along and unfolds the back folded in half.

   
   

   The result is a spacious sleeping area. Whereas when folded it is very compact. But such an advantage also translates into a significant drawback: a lot of space is needed for an unfolded sofa, which will be fatal for a small room. In addition, such a mechanism requires considerable effort.

8. French folding bed - this option is hardly suitable for everyday use, but as an additional guest place it is quite suitable.

   
   

   The back of this model is usually replaced by pillows, which are removed before transformation. After that, the seat sequentially unfolds into three sections (according to the clamshell principle), forming a roomy place to relax. This type of mechanism is not reliable. In addition, there are uncomfortable gaps between the unfolded sections that interfere with comfortable rest. In addition, there is no laundry box.

9. American clamshell - unlike the "French" counterpart, this type of mechanism is more reliable and will withstand frequent transformations. It unfolds a little differently.

   
   

   First, a block with a folded component is pulled out of the sofa body. The seat of the pull-out unit rises, and the composite section unfolds forward like a clamshell and is installed on the legs. It turns out a spacious bed. However, not very comfortable seams remain between the sections. In addition, there is no compartment for linen.

10. Spartak is a stylish sofa, the unfolding mechanism of which is similar to the "American folding bed". Before starting the transformation, the pillows are removed from the seat.

    
    

    After that, a sofa block is lifted from the body, which, in turn, is decomposed into two more sections, which are installed on the legs. All sections are made of durable metal, which significantly reduces the weight of the structure in comparison with standard elements of other types of sofas. However, this design makes it impossible for the sofa to store bedding below.

11. Roll-out - another type of mechanism, characterized by both simplicity and reliability.

    
    

    At the heart of its transformation is a retractable front part, on which there is a pillow folded in half. This pillow unfolds and fits into the vacated space. A spacious, and most importantly, a sleeping place without seams is formed. However, the height from the floor of such a sofa may seem too small to someone.

12. Outdoor - perhaps the simplest and most economical type of sofa.

    
    

    The folding part, consisting of two parts, when folded, fits completely into the body of the sofa, forming its seat. Whereas, unfolding, it is placed on the floor without legs or supports. The design is simple and therefore reliable. But, of course, there can be no question of any box for linen.

13. Konrad - a model with a three-section mechanism. When assembled, this is a beautiful and stylish sofa, and when disassembled, it is a spacious place to sleep.

    
    

    It is transformed by pulling out the seat, from which, in turn, the third section with the lifting part extends. As a result, a place to relax is not only large in area, but also high. The mechanism of this model, although reliable, is quite heavy. But there are boxes for storing bedding.

14. Dolphin - a similar type of transformation is most often found in corner sofas. The principle of its operation is the extension of the lower section of the long side, followed by lifting the pillow up with a soft handle.

    
    

    As a rule, a corner sofa of this design has a backrest consisting of individual pillows. Pillows have to be removed when unfolding the bed. The mechanism is resistant to loads, but wears out rather quickly. In addition, a carpet laid on the floor will greatly complicate the extension of the section.

15. Kangaroo - the principle of operation of the mechanism is similar to the "dolphin", with the only difference being that in the unfolded state it is much higher above the floor.

    
    

    However, this design loses its reliability. And, like models with the dolphin transformation type, this sofa does not have a long service life.

16. Recliner is the most modern and progressive kind of transformation mechanism. It allows you to adjust the position of the individual parts of the sofa - backrest, armrests, footrest, etc., thus creating the perfect place for relaxation.

    
    

    On some more expensive models of such sofas, vibration massagers are installed, which are controlled using the control panel. In addition, the appearance of such sofas is the most solid and presentable. However, they also have significant drawbacks. A full bed on such a sofa is unlikely to work. And the cost of even the simplest models bites.

The choice, as we see, is huge. So a sofa with which transformation mechanism to prefer? The first thing to consider is the size of the family. For one person, a sofa with an “elf” mechanism or some kind of “book” will suffice. Singles who are not constrained in their means and who want to furnish, for example, a studio in a stylish and tasteful way, can spend money on a recliner sofa. If the family is very large, then the best option would be roomy sofas when folded - for example, corner ones. For a small family, sofas of any other types are suitable for spaciousness.

To save space, it is also worth focusing on models that, both folded and unfolded, do not take up much space. Also, preference can be given to models with a lifting mechanism for storing bedding - space for blankets, pillows and blankets will not be superfluous. This option is especially relevant for sofas with pillow backs. It is not worth dwelling on options with unreliable mechanisms. They won't live up to your expectations. Those who are accustomed to sleeping on a perfectly flat surface of the bed should also avoid folding sofas and other varieties in which irregularities form between the pillows over time.

Otherwise, the results of the choice will focus on the preferences of the person. After all, as it usually happens: you go to a store or to a website, you see a sofa and you understand that it is what you need. And all these mechanisms, advantages and disadvantages fade into the background.
