Mechanisms for transforming sofas. Sofa transformation mechanisms - which one is better to choose? What is the name of the sofa that does not fold out

The sofa is one of the most comfortable pieces of furniture. It is unlikely that something else can be compared with it in terms of comfort. It is much more functional than a bed. Due to the fact that there is a mechanism for unfolding the sofa, you can arrange an extra bed for an adult or a child.

Ideal for lovers of modern practical style.

Most apartments allow you to place such a piece of furniture without compromising free space. During the day, the sofa usually plays the role of a comfortable seat, like an armchair, but you can also “reclining” on it, and even sleep, if suddenly a dream overcame you at an inopportune time.

It is roomy with its fairly compact size, so it is appropriate in a room of any size.

Familiar to all furniture today has many modifications. It is chosen by the owners of commercial establishments, and the owners of apartments, and the inhabitants of country cottages.

Sofas are divided into a number of types, depending on the purpose:

• kitchen;
• for children;
• for the living room;
• for the office;
• for the hallway.

Quite compact, it will at the same time provide you with a full-fledged place to relax.

Mechanisms for transforming sofas for living rooms and children's rooms provide an increase in comfortable space. If necessary, it turns into a bed. The child can play on the floor, and then lie down to rest or read.

Unlike most corner models, it has a comfortable backrest for sitting and two sides with wooden armrests, which provide comfort for the whole family while watching TV or just relaxing.

Office, kitchen and hallway models usually do not have additional folding parts - there is no sofa transformation mechanism in them, because visiting these places does not involve spending the night.

Types of sofas by design features

A variety of designs allows you to choose stylish and practical sofas to your liking.

There are several types of structures that differ in shape:

• angular;
• straight classic;
• island.

A versatile sofa, because by transforming with a simple roll-out mechanism it turns into a comfortable double bed.

Corner-shaped furniture is convenient for small rooms where there is a free junction of two walls. Such sofas take up a minimum of space, may have additional modules (remove if necessary).

The spring block and the filling of polyurethane foam, an environmentally friendly material, ensures the anatomical position of the body during sleep, so that rest is complete and healthy.

The straight model is usually located against one of the wide walls. Not all models have sofa folding mechanisms with a similar design. To provide an extra bed, you need to choose furniture with a layout system.

The convenience of the sofa is added by the presence of a linen niche in which you can store bedding.

Types of island-type sofas can be different. The modules are laid out in the desired position, providing a wide area for lying down.

Long service life even with intensive use is possible thanks to the wooden frame.

Types of sofas by type of transformation

The type of sofa unfolding significantly affects the degree of comfort. If the sleeping place is planned to be large, then it is necessary to choose a design based on the area and layout of the room.

The original design of the sofa and its carefully thought-out forms will be the highlight of the room.

Sofa transformation mechanisms dictate the type of layout:

• "Book";
• "Tango";
• "Lit";
• "Dolphin";
• "Puma";
• "Pantograph";
• "Clamshell", etc.

This is one of the most popular mechanisms today.

When choosing, one must proceed from the extent to which one or another layout is within the power of family members, since tight and complex mechanisms can jam and require more physical costs for them.

At the heart of his bed is a high-quality spring block, which allows the child's spine to stay in an anatomically correct position, thus not bending

The mechanism of transformation of the sofa "Book"

One of the most popular types of sofas. Bringing the structure to a horizontal position takes a minimum of time. You need to pull the seat towards you, and lifting it until the lever is activated, you can easily lay out the sofa for sleeping.

While the child is small, the sofa can be used without unfolding.

The mechanism for transforming the sofa "Book" is reliable and simple, because it provides a sleeping place very quickly. You can use the furniture for a long time without loss of performance.

The sofa book combines the advantages of a classic sofa and modern functional solutions.

Types of sofas that transform for a comfortable position and sleep:

• straight;
• angular ("Eurobook" or "Tango").

Has practical armrests, a high and convenient back.

The latter have a shorter head part, a long (narrow) one unfolds flush with the head part - a solid area is obtained for a comfortable stay. The mechanism for transforming the sofa "tango" is similar to the mechanism for laying out a straight "book". It is necessary to pull the seat towards you and up until it clicks.

Filling - high-quality safe polyurethane foam with a spring block.

Click-clack sofa: increased comfort

Type of sofa, according to the layout principle, reminiscent of a "book". To bring the bed to a horizontal position, it is necessary to pull the seat up until a characteristic sound is heard.

The mechanism for transforming click-clack sofas is as simple as that of the previous type.

To unfold the sofa in a horizontal position for subsequent sleep, you do not need to make great efforts, unless the structure is severely deformed from long-term use.

The sofa will perfectly take its place in the living room or bedroom.

Of the mechanisms for transforming sofas, this one is one of the easiest. Often, such models can be seen in a teenager's room or bedroom.

The sofa will provide an extra bed if relatives or friends come to visit.

Sofas "Lit" and roll-out type

Two types of designs - "lit" and roll-out are also very popular due to the quick unfolding for sleep. The sofa "lit" is transformed easily. Armrests can be placed both for a children's bed and in order to arrange a comfortable sleeping place for an adult. To bring the sofa into the desired position, you need to pull the seat towards you, fixing it after the lever is activated.

Roll-out furniture does not require effort, the load goes to the rollers. When moving towards you, the parts are transformed into a horizontal position, it remains only to align them and place pillows for convenience. The sofa provides an extra bed for an adult or two for children.

Filling - high-quality safe polyurethane foam with a spring block.

Mechanisms "Puma" and "Dolphin"

The Puma layout type is also a leader among simple sofa mechanism control systems. In a horizontal position, the structure is brought in one or two movements. It is enough to pull it towards you until it stops - an additional part will appear, previously hidden inside. The third part is filled with a back.

The sofa with the Dolphin mechanism is also distinguished by a similar compactness. The difference is that an additional block extends from the bottom of the furniture, which then becomes flush with the surface. The bed is large, and when folded, the piece of furniture is very ergonomic.

With the help of the mechanism, you can easily expand the sofa, getting a full-fledged double bed, while for your convenience there is a spacious linen niche.

Choosing a sofa depending on the size of the room

When purchasing folding furniture, you need to focus on the area of ​​\u200b\u200bthe room where it is supposed to be placed.

• For children's rooms, sofas of a single layout such as "book", "lit" or roll-out are suitable. The size of the sofa also matters. For children, choose the environment in specialized departments of stores, as there products undergo strict environmental certification. Furniture will be safe from the point of view of mechanics.
• For living rooms and bedrooms of large sizes and with a square layout, sofas with a double layout are convenient. They provide, if necessary, a replacement bed, and you can stay on them with great convenience.
• Pull-out sofas are a great alternative to beds in a country house where there are several small guest rooms. During the day, you can sit on them, reading a book or watching TV, and at night you can sleep comfortably.

Elegance is added by spectacular wooden legs.

Quality of mechanical parts

When choosing a folding sofa, give preference to reputable manufacturers, and in the store repeatedly check the mobility of the mechanisms, since typical models may contain defective parts. If the mechanics are tight, there is a feeling of looseness of the guides - the question arises of little quality control on the part of the manufacturer.

The best option would be to make a sofa to order. With this approach, you can not only purchase a quality item according to individually declared sizes, but also control the progress of work. In most cases, you will also avoid overpaying. The furniture will pass careful control before you receive it in finished form.

The sofa will perfectly take its place in the living room or bedroom.

sofa operation

Despite the guarantee issued by the sofa manufacturer, under certain influences, it can become unusable much earlier. It is required to handle a folding sofa carefully - try not to pull the folding parts and not take them to the sides, loosening the transformation mechanism.

Since the hinges and levers are predominantly metal, they do not tolerate excess moisture. Therefore, when cleaning the sofa, try to use a wrung out sponge or a slightly damp brush. Contact with caustic detergents on the mechanisms can cause metal corrosion.

The base of the sofa frame is made of natural wood, the body material is high-strength fiberboard.

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 bed 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!

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. To transform, you need to pull the seat forward with the help of the hinges, 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.

This 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 similar to a "cot" hidden under the sofa's modular seat mats. Even externally, 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 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, this 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);
