What types of sofas are there. Types of sofas

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 such 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 house 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 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, 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);
• 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.

Let's open the secret: there are no "bad" and "good" transformation mechanisms, there is a wrong approach to choosing the right model. To understand what sofas are, to find "your" option will help a review with short illustrative videos.

When choosing the type of transformation, pay attention to how the sofa unfolds, lightness and speed, contact with the floor and the presence of a linen box. The purpose of the future sofa is also important - daily use or unfolding from time to time?

Book

A mechanism familiar to many since childhood. The transformation from sofa to bed is simple and intuitive. Time-tested folding sofas are equipped with a spacious linen compartment under the seat and have an attractive price due to the simplicity and unpretentiousness of the design.

How to decompose: the seat moves up until it clicks and then goes down. The back takes a horizontal position, forming a flat surface for sleeping and relaxing.

What is good: low price, quick unfolding method, capacious laundry box.

Things to remember: the distance from the back to the wall must be at least 10 cm, for unfolding it is necessary to make an effort.

Eurobook

Reliable and easy to use sofa transformation mechanism. Due to the absence of loops at the junction, the sleeping surface is smooth and comfortable. The bed is located along the sofa, which is ideal for narrow spaces. No need to think about how to unfold or fold the "Eurobook" and there is no need to move it away from the wall every time - the design of the model moves forward.

How to decompose: Roll out the seat and lower the backrest - the place to rest is ready.

What is good: reliability and, there is no need to move the sofa every time it is unfolded, suitable for narrow rooms.

Things to remember: models without wheels may scratch the floor.

Pantograph

This variety has all the advantages of the Eurobook, and even more. Rising sofas are not equipped with rollers and move apart without touching the floor. The lifting mechanism pushes the seat up and it seems to step forward, leaving the flooring intact. The reverse folding mechanism is also effortless.

How to decompose: pull the seat up and towards you and lower the backrest.

What is good: does not interact with the floor, equipped with a linen compartment, no need to move when unfolding.

Things to remember: unfolding requires more effort than in the "Eurobook".

eurosofa

Folding systems on a metal frame are reliable and durable. Perfect for active daily use, they will easily endure rearrangements and moving.

How to decompose: press from top to bottom on the edge of the back - gently lowering, it will take a horizontal position. To reverse the transformation, pull the backrest frame up.

What is good: has a metal frame at the base, does not require moving the sofa away from the wall.

Things to remember:the only disadvantage of such systems is the relatively high cost.

Dolphin

Sofa, which includes a mechanism"dolphin" , unfolds with particular ease and speed. The device was named after the animal of the same name due to the similarity of movements.

As a rule, it is found in corner sofas. The bed frame is held by special brackets at the level of the main part of the sofa. Due to its compactness, this model will successfully fit into the interior of a small room, and a spacious laundry box under the corner part will help to hide home textiles and household items.

How to decompose: slide the frame out from under the seat and pull it up.

puma

Like a cat, laid out as quietly and accurately as possible. No scratches from the legs or dented tracks from the wheels - even the most demanding flooring will not suffer during daily unfolding. When transforming, minimal effort is needed: pull the seat up a little, and then the mechanism will do all the work.

How to decompose: pull the bed towards you by the seat, and the part below will appear behind it.

What is good:noiselessness and respect for the floor covering, it is easy to unfold.

Things to remember: straight models do not have a laundry box. For corner models, it is located behind the ottoman.

Accordion

It got its name due to the similarity of unfolding with the movement of the bellows of a musical instrument. The bed is flat and wide, without tangible joints. The model belongs to the category of sliding sofas and noticeably eats up space in length, choose it if the space allows such room for manipulation.

How to decompose: pull the loop and the seat will move forward, and the back will turn around and split into two parts.

What is good: ease of unfolding.

Things to remember: requires a lot of space for unfolding, so do not place a table or other furniture in front of the seat. The mechanism needs to be looked after and regularly lubricated.

Caravan

The mechanism of unfolding on a metal frame, reliable and durable. Due to the transformation forward, it organizes a wide berth (analogous to a double bed) with a relatively small size of the “caravan” sofa.

How to decompose: pull the seat up - it will begin to describe an arc in the air. At the same time, two additional platforms will appear from under the base one after the other. When the seat is lowered onto the supports, the three functional parts form a flat sleeping surface.

What is good: design reliability and ease of transformation.

Things to remember: since the place under the “caravan” seat is occupied by additional platforms, sofas of this type do not have a linen box.

French cot

French cot or"sedaflex" - light and compact European guest solution. Due to the design features, the model unfolds much longer than the “cougar” or “eurobook”, it does not have a linen box, and also such a sofa is not suitable for daily unfolding. If you need an option for frequent use, look for a French clamshell model with a wooden frame in the support base instead of fabric - this option is more beneficial for the spine.

How to decompose:lift the top seat cushion and pull the legs forward - the sleeper, folded like an accordion, is hidden under the seat.

What is good: lightness and structural strength.

Things to remember: no box for linen, too soft bed (not recommended for daily sleep), sofas with a forward-folding mechanism do not always fit well into narrow spaces.

Rich

Mechanism "Rich" or"Spartacus" - American bifold bed. In its design - a metal frame and a welded lattice, reliable and durable. The system is suitable for both guest and daily use. The main feature of the mechanism is the ability to “remove” the seat under the bed, which automatically facilitates the task of transformation.

How to decompose:lift the seat and pull the system towards you - the folded double bed will appear from under the base.

What is good: easy to fold, reliable and durable.

Things to remember: The design does not include linens.

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!

Buying a sofa is a very responsible process, because such furniture is bought for more than one year. The choice must be approached with special care so that the new sofa is comfortable for all family members, successfully harmonizes with the interior and pleases with its functionality for a long time.

First of all, the sofa is a comfortable relaxation area after a hard day, a place for friendly gatherings and watching movies. Often it is also used as a place to sleep. When buying, we usually pay attention to the appearance, but it will be much more important to make sure of the quality of the material and check the folding mechanisms of the sofas.

Before you go on a furniture shopping trip in search of a sofa, answer the following questions:

1. How much space do you intend to allocate for the sofa when folded and unfolded?
2. How often are you going to lay out the sofa?
3. In what mode will the sofa sleeper function: daily or as a guest option?
4. What load should the sofa withstand?
5. Do you need a special place to store clothes?
6. How much are you willing to spend on a purchase? Which model should you pay attention to: a budget option or a sofa with a more complex mechanism and reliable details?

Types of mechanisms, pros and cons

Types of sofas by folding mechanism:

• retractable, or withdrawable (on rollers): withdrawable, dolphin, eurobook, conrad, pantograph;
• folding: tango, book, elf;
• deployable: accordion, French cot, American cot, Spartak.

Let's consider in more detail each of the options.

Book

Having such a mechanism for transforming sofas, a piece of furniture is converted into 2 positions: a seated version and a sofa for sleeping. To turn the sofa into a sleeping place, its back is simply folded back. It will not have to be moved away from the wall during this process, since during installation it will be necessary to take into account that the design of the furniture requires a small gap between the wall and the back.

Parts of a sofa with a "book" mechanism are two metal or wooden frames with fixed or other soft filler. At the bottom, there is often a compartment for storing clothes.

Pros:

• strength;

Manufacturers of upholstered furniture use a variety of layout mechanisms for sofas. There are no universal options. Depending on the method of operation, the size of the room and some other conditions, one or the other is chosen.

In order not to make a mistake, you need to listen to the advice of experts. They will help you understand what factors you need to pay attention to in the first place. All groups of mechanisms are classified according to certain criteria. This makes it much easier to figure out which model is best suited.

studying, which mechanism for transforming sofas is better a number of recommendations should be taken into account. There is a generally accepted rule. All sofas are conditionally divided into guest types and designed for daily sleep. If the mechanism is chosen correctly, the furniture will last a long time. Its operation will be comfortable.

If the sofa will be laid out often (sleeping variety), you should not purchase products with a complex layout procedure. In this case, it would be useful to remember the golden rule: the simpler the better. Guest sofas, on the contrary, are not designed for the daily movements of the system. Therefore, their mechanism will not be as strong as that of sleeping varieties.

Attention should also be paid to such criteria as the maximum load of the bed, the orthopedic qualities of the model, its appearance, the layout procedure, the comfort of the bed, and also the convenience in the sitting position. So sofa transformation mechanism is an important factor influencing the choice.

Guest models

Guest type sofas have a design that does not take up much space. The appearance of such furniture is very unusual, interesting. Such mechanisms include "French folding bed", "Sedaflex", "Dionysus", etc. The main purpose of such furniture is to surprise guests, ensuring their maximum comfort during their stay in the hosts' house.

Comfort in a sitting position is important, but you won’t be able to kill two birds with one stone, you will have to sacrifice comfort when laying out. Mechanisms for transforming corner sofas require a significant investment of time and effort in order to transform furniture into a place to sleep. First you need to remove the seat cushions. After that, the mechanism is activated.

If you believe the reviews, rest in such a bed leaves much to be desired. These types of sofas are usually cheap. You can sleep on them, but not all the time.

Sleeping sofa

The second group includes furniture designed for daily sleep. When laying out, you do not need to spend a lot of time. Sleep will be comfortable. Devices of this type include the "book" and its main variations. The most famous of them are "click-clack" and "Eurobook".

This type includes angular varieties. The most popular in this group is recognized the transformation mechanism of the sofa "dolphin", well, or"puma". Also bright representatives of furniture for daily sleep are sofas "telescope" and "ribalto".

Such mechanisms are very easy to operate. Their transformation is quick and easy. The sleeping place has sufficient rigidity. It is flat and comfortable. Such mechanisms are designed for a large number of transformation cycles.

"Book" or "click-clack"

One of the simplest is sofa book. Transformation mechanism involves raising the seat. At this point, a click occurs. The sofa comes back down already unfolded.

Click-clack models are a slightly improved version of the book. Such devices have an intermediate position. At the same time, a person can be in a “relaxation” position. The back does not go all the way down. Therefore, a person is located on the sofa half-sitting.

The advantage of the presented models is reliability and durability even with daily transformation. This option is ideal for apartments with a small area. Floor covering can be anything.

The disadvantage is the limitation in design, simple appearance. The back and seat of such models must be identical in length. A variety of "click-clack" should not be placed close to the wall.

"Eurobook"

One of the most common models today is the Eurobook. The sofa transformation mechanism is considered one of the most reliable. When folding, the seat is pushed forward. Under it opens a space for storing bed linen. The back rests on the vacated space.

The advantage of such a system is the minimum number of mechanical elements. Therefore, there is practically nothing to break in such furniture. According to consumers, these are durable reliable products. The sleeping area is very spacious. In addition, there is a rather large box below. It is convenient to store bed linen and bedding here. The sofa can be installed near the wall.

As for the disadvantages of such products, people note that the seat slides on the floor. Therefore, special attention is paid to the coating. In general, the "Eurobook" is a solid reliable mechanism that will serve its owners for many years.

"Pantograph"

One of the analogues of the "Eurobook" today is the "pantograph". The sofa transformation mechanism is also quite simple. It is necessary to raise the seat at an inclination of about 45º. Then it is lowered and pulled down and towards itself. The back goes down. This is how the bed is made.

Below is a laundry compartment. Some models of the presented variety can be transformed from a direct to a corner version of upholstered furniture. And it doesn't matter if you want to turn it right or left.

The advantage of this mechanism, judging by the reviews, is that the seat does not roll out on the floor surface. It simply slides out without touching the flooring of the room. The improved design causes an increase in the cost of such sofas.

"Cot"

The "clamshell" type has several popular design options. The principle of transformation here is simple. The bed is located directly under the seat. For the front panel, which is located below, the seat moves forward. There is a French and an American folding bed. Their principle is very similar.

The French one is pulled out in the form of a scroll, which unfolds in 3 stages. This mechanism is compact in size, so it is built into even very sophisticated sofas. However, this model is not used on a daily basis.

The American clamshell is designed for heavy loads. This sofa is practical and durable. However, this feature significantly raises the price of this furniture. To transform the sofa, you need to lift it a little, and then pull it towards you. This type of mechanism does not harm the flooring, but it needs to be lubricated periodically to avoid squeaks.

Withdrawable mechanism

One of the best options for sleep is considered roll-out sofa. Transformation mechanism here is very simple. The berth is obtained by rolling out additional sections from under the base. Due to its simplicity, the presented mechanism is called one of the most reliable.

Another advantage of such products is the absence of requirements for the size of the room. It is installed even in small rooms. Moreover, in the unfolded state, the place to sleep will be long and even.

The disadvantage of such mechanisms is the exactingness of the type of flooring. It should be strong, not sag under the weight of the sofa. In the process of transformation, the base slides on the floor. Nothing should interfere with this movement. It is better if the selected model of the presented type has rubber wheels.
