Sofa folding mechanisms - what are they and what is better? Consider the mechanisms of modern sofas: types and purpose Types of sofas.

Apply 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 another mechanism for transforming the sofa is selected. 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.

When studying which sofa transformation mechanism 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 and 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, the simpler the better. Guest sofas, on the contrary, are not designed for the daily movements of the system, so 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. Therefore, the sofa transformation mechanism is an important factor influencing the choice.

Guest models

Sofas with "Clamshell" mechanism

The folding bed sofa transformation mechanism 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 American cot, 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 sleeping is a roll-out sofa. The 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.

Sofas with accordion mechanism

The mechanisms for transforming accordion sofas are gaining more and more popularity. It is very easy to apply in everyday life. The principle of the design device is to push the accordion. To do this, the seat is slightly raised. Next comes the click. The back of the two parts (in the normal state, it is folded with a house) is stretched. It resembles the movement of an accordion.

With the help of such a transformation, a flat surface is formed. When unfolded, the sofa looks like a regular bed. Usually "accordion" has removable covers for all soft elements. This makes the cleaning process easy. In the kit, almost all models have a linen box. In some cases, other decorative elements may be present. It is better if the basis of such furniture is a metal frame, steel frames. The mattress can be chosen orthopedic. For a small room, this option is acceptable, but you need to consider how much space the sofa will take up when disassembled. On the way of its layout there should be no extraneous things. There should be at least 0.5 m of space left to the opposite wall when the "accordion" is disassembled.

Sofas with the Dolphin mechanism

The dolphin sofa transformation mechanism can also be called a kangaroo. It is most often found in sofas in the form of an angle. The front part slides out. An additional pillow is taken out of it with the help of a loop. She forms a bed. These sofas are quite large. The storage box is hidden in the corner module. The advantage of this model is a reliable and simple mechanism. This is an option for daily sleep. It is able to withstand heavy loads (about 200 kg). When laid out, an additional part of the structure takes up a minimum of space in the room. It should also be noted that the bed is spacious and has a fairly high rise above the floor level. The cost of the presented furniture is relatively low. This makes the "dolphin" very popular.

Swivel mechanism

One of the most modern is considered a corner sofa with a swivel transformation mechanism. It works very simply. One half of the furniture is rolled to the side 90º, and then it must be rolled to the other part of the sofa. It does not require the use of significant physical force. All movements are smooth. After the transformation is completed, the turning part is fixed. This creates a comfortable and spacious bed. The simplicity of the design makes the mechanism durable. It is possible to use orthopedic sofas for sleeping. It comes with a spacious bottom drawer for storage. On sale, such varieties of sofas are still quite rare. Their prices are above average. Therefore, if you want to purchase an easy-to-use, reliable and modern sofa, which is the corner swivel mechanism, you will have to spend some time looking for a responsible, trusted supplier.

• cannot be moved close to the wall - there should be 20–30 centimeters left for free play when unfolding;
• an uneven sleeping place is obtained due to a clear separation of soft surfaces in the middle;
• transformation requires some effort.

"Eurobook", "Tick-tock", "Pantograph"

An equally popular model on the market is the eurobook sofa. He has a very simple way of unfolding: the seat is pushed forward, and the backrest fits into the vacated space.

In the “Tick-Tock” model, the transformation takes place on weight along a semicircle trajectory on springs, that is, it is not necessary to carry the retractable block along the floor. This makes such a mechanism more attractive, and the model is sometimes called the "Walking Eurobook".

The advantages of sofas include:

• reliable mechanism;
• ease of unfolding;
• spacious inner drawer;
• flat bed;
• choice of sizes.

Of the shortcomings, a deep seat can be noted, which may not always be convenient. But this problem is easily solved with the help of sofa cushions.

"Accordion"

This type of transformation of upholstered furniture has firmly won the sympathy of consumers. This can be explained by the increased reliability of the design and the ease of turning the sofa into a bed. To unfold it, you need to lift the seat and pull it towards you. At the same time, the backrest, consisting of two parts, moves forward, and all the elements are laid out like an accordion in one plane.

This is a stable and easy-to-use model, but it has one significant drawback - there is no box for linen.

Withdrawable or "Telescope"

The layout mechanism of the structure is very convenient. First, the main seat of the sofa rolls out to the stop. At the same time, the headrest of the bed extends from behind the back. An additional seat or lumbar soft part is placed in the resulting niche between the two sections of the sofa.

"Telescopes" when folded are very compact, so they can be used even in small spaces. After the transformation, a fairly wide and comfortable bed is obtained.

The disadvantages include the small height of the bed and the fact that the movable mechanism can damage the flooring.

Folding bed - French type, American (sedaflex) and Belgian

In sofas of this type, the bed is pulled out from under the seat, and then the sections are unfolded and placed on supports or legs.

French - sections are folded three times under the seat. To expand the structure, you must first remove the top cushions. Not very suitable for frequent use, as the mechanism wears out quickly.

American (sedaflex) - unlike the previous model, it has two sections and is completed with a thicker mattress. When the sofa is laid out, the low back is lowered and becomes part of the bed. Reinforced mechanism allows you to use it as an everyday place to sleep.

Belgian - can have both two and three additions. The filling and height of the mattress depends on this.

Dolphin and Kangaroo

The design of furniture with a durable reliable mechanism "Dolphin" is simple and convenient. To expand the sofa, you need to pull out a special block from under the seat, and then remove the second part of the structure from it upwards and towards yourself.

Experts consider this mechanism the most durable of all types. They are often equipped with corner models. They have a spacious and flat place to sleep, and a box for storing bed linen is installed in the side part.

The mechanism "Kangaroo" differs from the "Dolphin" in the ability to create upholstered furniture with higher legs.

"Conrad"

A sofa with such a folding mechanism is considered the most comfortable for sleeping. The design has the ability to use spring blocks. The mattress is close in parameters to orthopedic, which improves the quality of night rest.

It is not difficult to lay out such a sofa: the part located under the seat is pulled forward, and with it the rest of the sections. A distinctive feature and an undoubted plus of the sofa with the Konrad mechanism is its compactness when folded and the ability to turn into a comfortable bed.

"Lit" or "Elf"

If you need to get a small place to sleep, then you should pay attention to compact models with the Lit or Elf mechanism. When unfolding, it will be enough to lower the adjustable armrest, and the sofa will turn into a comfortable single bed. In this case, the back does not move, and the seat becomes a sleeping place.

"Puma"

The Puma design differs from other models in that it does not touch the floor when unfolded. The mechanism is equipped with a special spring system that allows you to reduce the force during transformation: you need to grab the front edge of the seat, push it up and easily pull it towards you. The middle part of the bed gently rises from the inner space and takes its position.

The designs are very durable, they can be both straight and angular, while the latter have a box for linen.

With unfolding on the floor

This is the most budgetary model of all transformation mechanisms. Two sections of the bed are laid out directly on the floor, as they do not have supports. When folded, they are inside the case. For daily use, this type is not very comfortable. It is better to use it as a guest option.

"Spartacus"

The mechanism "Spartacus" resembles the "French cot", but has a welded grille, which strengthens the entire structure. Therefore, such models can be used for everyday use. The inconveniences are the same as in all folding beds: in order to unfold, you must first remove the pillows, and there is no box for storing linen.

"Recliner"

The Recliner sofa layout mechanism is equipped with a special system that allows you to change the angle of the backrest, and a footrest. Such models are high-tech, often have vibration massage systems and remote control using a remote control.

The sofa is designed taking into account the anatomical features of a person, so it is convenient to relax on it by adjusting the position of the back and stand. The disadvantages include the high cost and the impossibility of a full-fledged layout to get a bed.

Transformer

Models "Transformer" have a swivel type of unfolding, they look stylish and modern. Turning such a sofa into a bed is very simple: one part rolls back at an angle of 90 degrees and moves back. It turns out a spacious place to sleep.

For convenient unfolding, the sofa is equipped with rubberized wheels, so moving the swivel part is not difficult. The mobile module can also be moved in the opposite direction. Some models have a fold down back and all have two large storage drawers.

"Caravan" and "Daytona"

"Caravan" allows you to transform a sofa into a bed due to a complex metal structure. The main plus is that it unfolds in just one movement, and in its normal state it takes up little space. This makes it possible to install such models in small spaces. They fit especially well in the interior of the children's room.

"Daytona" - the design of a new generation of double decomposition. To turn into a bed, you need to pull the backrest, which falls and wraps under the bed. It is very convenient that you do not need to remove the pillows during the transformation. Strength and durability is ensured by a metal welded frame and elastic straps. Great for daily use.

"Saber"

Refers to roll-out, but the design of the "Saber" is more complicated than that of similar models. The seat moves forward if the backrest is moved forward towards you. At the same time, the backrest and headrest tip over and lie on the spacious inner box. It turns out a bed on which you can sleep comfortably.

What to look for when choosing a sofa

When choosing, it is necessary to inspect the mechanism, ask the seller in detail about the pros and cons of various modifications. The service life of new furniture will depend on the correct selection of the design.

You can draw and take with you a plan of the room indicating the dimensions, so as not to be mistaken with the dimensions and accurately calculate how the model you like will be placed, whether there is enough space for unfolding.

It is worth clarifying information about the filler. Be sure to independently assemble and disassemble the sleeping system and make sure that the transformation is convenient.

Block filler

Manufacturers use a variety of materials to fill the soft parts of furniture: pillows, backs, seats, armrests.

1. Spring blocks - provide additional comfort for the body during sleep, there are three types: dependent, "snake", independent.
2. Polyurethane foam (PPU) or foam rubber - highly elastic and inexpensive, environmentally friendly, has good elasticity.
3. Felt and padded jacket - natural materials, the first is obtained from sheep and goat wool, the second - from cotton wool. Felt acts as a protective layer for polyurethane foam and spring blocks, while their surface becomes more resistant to wear. The padded jacket is laid between layers of filler for increased comfort.
4. Sintepon is an inexpensive and high-quality artificial filler that gives furniture softness, elasticity, is not susceptible to the formation of fungus, but does not hold its shape well.
5. Hollofiber - looks like fluffy balls of different sizes, made from polyester fibers, quickly restores its original shape, warm and soft;
6. Holcon (strutoplast) - elastic and warm, environmentally friendly, does not absorb moisture and odors.
7. Periotek is a modern non-woven material consisting of polyester fibers, durable, resilient, breathable, fireproof.
8. Struttofiber - wear-resistant, elastic.
9. Latex is a natural material used in the manufacture of expensive models of upholstered furniture, has increased elasticity, is non-toxic, quickly restores its original shape, does not cause allergies, and has a long service life.

For sleep, it is preferable to choose models with spring blocks. They will give the body the greatest relaxation and proper rest. The main advantage of such systems is durability and strength.

Before buying, it is important to understand the features of the device of various models and choose the most suitable one depending on the purpose and frequency of use. Experts do not advise buying the cheapest options, because the quality will be low, and the service life will be short.

The sofa has become an integral and absolutely necessary part of our home life. But, if it will be used as a sleeping place, its choice becomes an even more serious task. Choosing the right sofa bed for any of the rooms of an apartment or house is very important. After all, you have to deal with him every evening and morning.

In this article we will talk about choosing a sofa folding mechanism and which layout mechanism to prefer. We will tell and show how sofas are laid out.

How to evaluate the mechanism for turning a sofa into a bed

There are four criteria for this:

1. how the bed is located relative to the back - perpendicular or parallel;
2. whether the mechanism is so reliable that it can withstand daily use, or is it only suitable as a guest sofa;
3. how convenient is it to lay out the sofa;
4. is it possible to quickly fix the mechanism if it breaks.

It should be noted that with the location of the bed parallel to the backrest, it will always be narrower than that of a sofa that unfolds forward (perpendicularly). Indeed, with an increase in the width of his bed, the depth of the seat and the height of the back of the sofa increase accordingly, and it becomes uncomfortable to sit on a folded sofa. While the width of the perpendicular berth is equal to the width of the sofa.

Eurobook

Eurobook is one of the most popular sofa folding mechanisms.

When unfolded, the bed is located parallel to the back.
To expand the sofa, the eurobook seat stretches forward.
The back rests flat and rests on the seat.

Characteristics:

• the bed is stable and comfortable;
• the eurobook sofa usually has a box for linen;
• The Eurobook sofa mechanism is reliable, can withstand loads up to 240 kg. But, if it still breaks, then it is not repaired;
• it folds out easily and quickly, but this requires the sofa to stand a short distance from the wall or it will have to be moved back and forward again daily (will this cover your floor?).

Accordion

Accordion sofas are valued for their high compactness, reliability and comfortable sleeping place.

To unfold the "accordion" sofa, its seat must be pulled out by a special strap, and the back folded in half unfolds like an accordion.
To fold the accordion sofa, the front part must be raised until the mechanism operates, and then lowered by pressing on the edge to fold the back and slide.

Characteristics:

• high and wide berth with a box for linen;
• the sofa mechanism "accordion" is easy to use and reliable;
• sofa "accordion" is inconvenient for laying out on carpets with a long pile;
• breakdowns are easily eliminated, but the mechanism requires periodic lubrication;
• at loads over 180 kg daily transformation is not recommended.

Dolphin

A popular and widely used sofa folding mechanism, especially in corner models.

click-clack

Click-clack sofas are the most comfortable for relaxing due to the presence of a relax position of the back or armrests.

The deployment is parallel.
When unfolding, the sofa is tilted onto the back and moved forward. The seat is lowered horizontally.
The back of the "click-clack" sofa can be fixed in the third position (except for lying and sitting) - half-sitting.
There are also single models of click-clack sofas, in which only the sides fall.

The spread is perpendicular.
There are several types of such mechanisms with slight differences. The most common French and American models.
The clamshell sections unfold sequentially. Each of them is mounted on metal legs.
The strongest are American folding beds. But in any case, they are not suitable for daily transformation. This is a guest sofa.

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 must 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 vacant 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, when 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.
