It is difficult for any of us to imagine a living room without a sofa. This soft component of the interior gives people a feeling of warmth and comfort, a sofa in any home occupies one of the most important places. On it, people relax, play, communicate with family and loved ones, as well as read, watch TV and sleep. In order to decide on his choice, you need to clearly understand what models exist and what functions they perform.

Now more and more new corner models and designs for the house are being produced all the time. In such a number of offers, it is quite difficult for the buyer to make a choice and understand which type is right for him. In most cases, a person chooses a model based on its appearance and the material from which it is created. But with such indicators it is difficult to achieve complete comfort in using the sofa. For example, such a choice is suitable for furnishing a room and giving it aesthetics, but not used often. For the same purposes, there are monolithic sofas, otherwise they are called non-folding. They can be seen in public places and shopping stores.

It is a completely different case when a sofa is bought for frequent use in everyday life. So, we can assume that such a model will be laid out every day for sleep. . To choose the right model and not to make mistakes, you should know and understand what are the mechanisms for transforming sofas.

You should also provide for other criteria for the chosen model: the size of the space required for the sofa, the ease of transformation, the availability of space where to put the bed linen. You should also determine for yourself which type of sofa is better.

The classification of all designs of sofas is carried out according to:

1. Transformations.
2. Design features of furniture.
3. Appointment.
4. Size and capacity.

Types of mechanisms

Names of sofas

Classification by purpose

All models can be divided according to their purpose:

1. Office furniture.
2. Living room furniture.
3. Kitchen furniture.
4. Hallway furniture.
5. Furniture for a children's room.

With all these varieties, sofas and their mechanisms will differ significantly from each other, so you should accurately determine the design of the sofa and its purpose. In most cases the purpose can be determined by the material of which the furniture is made.

Those sofas that are sheathed in leather or more budget materials are usually located in offices or kitchens.

Modern sofas do a good job of organizing a bed. Thanks to such an option as transformation, you can save space in the living room and provide comfortable conditions for sleeping.

Manufacturers offer many design options for upholstered furniture and various folding sofa mechanisms. Which one is better for every day? - this is the most important question with such a large assortment.

Which sofa mechanism is better for daily use (sleep), and which option to choose if the sofa is intended for the living room and will rarely be laid out? To make the right decision, we recommend that you familiarize yourself with the features of existing transformational mechanisms.

Folding sofa models have gained well-deserved popularity. Monolithic options (without a transformation mechanism) exist and can also be installed in a living space, for example, in a kitchen or hallway, but they are less functional.

If you are focused specifically on a folding sofa, then which mechanism is better to choose will be the envy of several factors. What matters is how often you plan to use it for sleep, how many square meters in the room are available for this piece of furniture and what operating period you are targeting.

Classic sofa bed. To organize a surface for sleeping, you should raise the seat, while the back will take a horizontal position. Now you need to return the seat to its original position - the "book" has opened.

Pros:

• durable and simple mechanism, it is almost impossible to break it;
• takes up little space and is suitable for small rooms;
• there is a compartment for bed linen.

• the body can be moved as close as possible to the wall, only if it will not be transformed daily into a sleeping place. The sofa can be moved apart only if there is free space behind it;
• in the area of ​​\u200b\u200bcontact between the back and the seat, a tubercle or depression may occur over time, this reduces the comfort of the bed;
• a compact (perhaps cramped for some) sleeping surface.

Important! The “book” mechanism has an elementary device, but in order to expand the sofa, force is often required. Therefore, it will not be entirely comfortable with constant use for a woman or child.

Tango

A modernized and more comfortable variation of the "book" mechanism. Some manufacturers stick to the name "click-clack".

• the backrest, in addition to the vertical and horizontal position, can be fixed at an angle and create conditions for comfortable rest (reclining);
• the mechanism is simple and adapted for regular use;
• there is a spacious box for storing bed linen.

• it will not be possible to install the sofa close to the wall, free space is required to recline the back;
• efforts must be made to transform.

The case can be moved as close as possible to the wall, the transformation is different than the standard "book". The seat extends (rolls out on rollers), creating an empty area that is equal to the height of the backrest. The backrest fits into the space that has arisen and a sleeping place is obtained.

• the sofa is easily converted into a comfortable bed, the sleeping surface is spacious;
• the system is durable and easily withstands regular use;
• internal niches for storage of linen are provided.

• a sufficiently deep seat, leaning on the back is most often obtained only by climbing onto the seat with legs or using additional sofa cushions;
• if there are no rollers on the exit part, the floor may be scratched.

Interesting fact! Every year they become more and more popular. All models work using a single mechanism, but there are differences in design. You can purchase a sofa without armrests, with only one or with two on the sides. There are also differences in size. For example, you can choose:

Pantograph

This mechanism is arranged by analogy with the Eurobook. To prepare the area for sleeping, you need to pull the seat up. At this point, a mechanism is activated that will move the seat up and forward, and then extend the support elements. The back is placed in the resulting empty zone.

• a wide monolithic and even surface for sleeping (the joints are not felt);
• the mechanism provides ease of transformation, no additional effort is required;
• the seat does not slide out along the floor, so the parquet or laminate will not suffer;
• there is a compartment for storing linen.

• a complicated mechanism increases the cost of the sofa;
• deep seat: in order to lean on the back, it is often necessary to use additional pillows.

puma

Comfortable to use mechanism that is activated with one movement. It is enough to pull (raise) the seat and it will automatically move forward, move to the desired area, and that part of the structure that is laid inside the body will take its place.

• minimum effort for unfolding the sleeping space;
• the movable element does not damage the flooring, since the main movement occurs on weight.

• a compartment for storing bedding is provided only in corner models.

Elf

A very simple system to organize a sleeping surface, just lower the armrests. The frame is made of metal pipes, the base of the bed is made of wood.

A distinctive feature of the sofa is that the armrests are easily adjustable and you can create comfortable conditions for relaxing in a reclining position.

• the body is compact and does not require additional space for organizing a bed;
• sleeping surface with orthopedic effect;
• There is ample storage space for linens.

• the seat is also a sleeping surface;
• the sofa is installed at a small distance from the wall, not close.

The process of unfolding the sofa takes place on the principle of the movement of accordion bellows. When assembled, the sofa is compact, but to expand it, you will need at least 1.5 m of free space in the room.

• spacious and comfortable sleeping area;
• compact body.

• the transformation of the sofa into a sleeping place is accompanied by the movement of the supporting elements along the floor, scratches may remain on the surface of the floor covering;
• you need to make an effort to unfold.

To bring the structure into the sleeping position, the seat must be rolled out and its top cushion folded onto the inner section.

• comfortable sleeping surface;
• takes up little space when assembled.

• small bed height;
• the movable element rolls out on the floor and can damage the parquet or laminate.

The berth is laid "accordion" under the seat. To transform a sofa into a bed, it is necessary to remove all decorative elements (most often pillows), pull out a folding bed and sequentially expand all three of its sections.

• neat and compact body;
• spacious sleeping area.

• not very comfortable surface for sleeping, thin mattress;
• there is no box for storing bed linen and accessories;
• the mechanism is not distinguished by strength and reliability.

Important! "French cot" is not suitable for daily sleep, but it is a spacious extra bed, which will come in handy if you have guests over.

Spartacus

The folding part is made of metal (frame and grids). The sleeping surface is completed with an orthopedic mattress. Preparation of a bed is carried out in three movements.

• stable system: the sofa can be safely laid out every day;
• comfortable and spacious bed.

• a folding bed occupies all the space in the sofa body and there are no niches for bed linen;
• metal can deform under load.

american cot

The sofa can be laid out daily, it is more resistant to stress than the French version. The seat rises and the three sections open one after the other, standing on the supports.

• spacious bed with a good mattress;
• reliable and easy to use transformation system.

• there is no compartment for linen and bedding;
• seams are felt on the sleeping surface, which are located at the junctions of the folding sections.

Sofa with unfolding on the floor

The folding design, consisting of two parts, fits entirely inside the sofa body. There are no supports for the sleeping surface, it is put forward and laid directly on the floor.

• compact body;
• the most economical option among folding sofas.

• sleep almost on the floor;
• no drawers for laundry.

Conrad

Three-section folding mechanism: to spread the sleeping surface, it is necessary to pull the lower seat support and roll out the sections one after the other. Conrad differs from standard roll-out mechanisms in the height of the sleeping area.

• reliable mechanism suitable for daily use;
• comfortable high bed;
• The set includes large boxes for bedding.

• heavy weight of the body and sliding system
• The high sleeping area may not be to everyone's liking.

The mechanism is often installed on corner sofas. The lower part of the long side of the corner rolls out and a pillow is pulled up from it with the help of a special fabric or leather handle.

• spacious comfortable sleeping surface;
• easily transformed and can withstand heavy loads;
• the presence of a capacious area for storing blankets, pillows, blankets.

• with frequent use, the mechanism wears out quickly enough (will last 5-7 years);
• used mainly on corner sofas.

Consider when choosing a sofa! also used in straight and modular designs. This sofa transformation method is quite simple, but pulling out the first section can be difficult due to the floor carpet.

Kangaroo

It transforms by analogy with the "dolphin" mechanism, but has higher supports. Thus, the sofa, both assembled and unfolded, has a good height.

• easily extends and unfolds the sleeping surface;
• good bed height.

• the service life is limited;
• unreliable design.

Recliner

The name of the mechanism is of English origin. It translates as "reclining".

The sofa is equipped with a complex system that adjusts the angle of the backrest and pushes a soft footrest from below. More advanced models suggest the presence of built-in massagers and the ability to control the system remotely using a remote control.

• you can adjust the backrest and footrest to fit your parameters and create a comfortable seating area;
• solid appearance.

• the sofa does not transform into a full bed;
• high price.

Mechanisms for transforming sofas - briefly about each

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

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

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

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

Sofas without transformation mechanisms

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

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

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

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

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

The mechanism of transformation of the sofa "Book"

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

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

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

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

Sofa "Book" often contains a section for bedding inside

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

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

The mechanism of transformation of the sofa "Tango"

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

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

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

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

Sofas "Tango" have a section for storing the bed

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

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

The mechanism of transformation of the sofa "Eurobook"

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

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

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

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

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

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

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

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

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

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

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

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

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

Advantages: in the assembled state it has small dimensions.

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

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

Sofa transformation mechanism American folding bed (Sedaflex, Sedaflex)

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

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

Reliability is its main difference..

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

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

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

The mechanism of transformation of the sofa "Italian folding bed

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

The principle of operation of the mechanism

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

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

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

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

disadvantages lack of storage space for linen, high price

The mechanism of transformation of the sofa "Accordion"

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

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

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

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

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

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

The mechanism of transformation of the sofa "Spartacus"

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

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

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

Sofa with unfolding on the floor

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

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

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

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

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

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

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

The folding mechanism of the sofa "Konrad" ("Telescope")

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

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

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

Disadvantages: mechanism and sofa are heavy

The mechanism of transformation of the sofa "Dolphin"

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

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

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

disadvantages: not durable.

The mechanism of transformation of the sofa "Elf"

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

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

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

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

Sofa transformation mechanism "Recliner"

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

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

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

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

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

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

General conclusions

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

Sofa transformation mechanisms - video review

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

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

Folding models of upholstered furniture have practically ousted other options from the market. Their versatility and practicality form a steady consumer demand. Responsible for these characteristics are the mechanisms for transforming sofas, which are being improved every year thanks to the innovative developments of specialists. Modern upholstered furniture has become more reliable and durable. And now a fragile woman and a child can turn it into a full-fledged sleeping place without any problems.

Purpose

Folding sofas are necessary to save usable space in the room. They can be used as the main bed, and the universal model will help out if guests arrive. During the day, such furniture is usually in a folded position and performs its direct functions.

The design, dimensions and folding mechanism determine the function of the sofa in the interior. For example, "Click-clack" requires more space against the wall, and "Tango" will take over the functions of the main bed in the nursery.

You can count several dozen modern mechanisms for transforming sofas. Each of them has its own design features and advantages. At the same time, the basic device of any sofa is approximately the same. Upholstered furniture consists of several basic elements:

• back;
• seat;
• armrests;
• frame;
• filler;
• upholstery.

In addition, it can be additionally equipped with pillows or drawers for storing bed linen and other things. The transformation device is a set of parts that includes a articulated lever mechanism, guides and rollers. Its main task is to increase the area of ​​\u200b\u200bthe bed. Usually the design is placed in the back and middle blocks of the sofa.

Overview of popular models

All types of sofas differ in several ways. By design, they can be angular, straight, modular. By the number of places - double, triple and more. Also, the furniture is equipped with a different mechanism for laying out sofas.

Depending on these criteria, products differ:

• dimensions;
• convenience;
• bed size;
• design.

Having studied the design features and clearly knowing your own needs, you can make a smart choice. First of all, it is necessary to take into account the regularity of operation - whether the furniture will be laid out daily or from time to time. In the first case, the most reliable mechanism is needed. And in the second, the main thing is that the furniture fits into the interior when folded.

Books

The most common type of upholstered furniture. By design, products can vary significantly, but the basic principle remains the same - the design of the sofa allows you to fold and unfold it like a book. The furniture consists of two halves moving relative to each other, which provide for two or three positions. To fix the sofa in any of them, just pull one of the parts towards you.

There are several types of this mechanism:

1. The usual "book" is the oldest of the existing models. Identical furniture options were still sold in Soviet stores. They have only two fixed positions and a simple transformation mechanism. This model is budget friendly. Inexpensive fabrics are used for upholstery, chipboards are used as a frame. The main drawback is the insufficiently even and spacious surface for sleeping. In addition, a similar mechanism for a sofa implies that the product will have to be constantly moved away from the wall. This is quite difficult, given that ordinary "books" are often equipped with storage boxes.
2. "Eurobook" differs from the usual "book" in that it does not need to be moved away from the wall. The folding mechanism allows you to roll out the front part, then the back fits into the resulting opening. The furniture is characterized by more impressive dimensions, it can comfortably accommodate two people. The sofa with the Eurobook mechanism can be used as a comfortable bed for one person, even when folded. The cost of such furniture is much higher than that of the previous model.
3. "Tango" ("click-clack") - options that are comfortable for sleeping, the main feature of which is the absence of a pronounced joint between the two halves of the "book". The furniture looks like a single whole, both folded and unfolded. The model is often equipped with armrests, which, when unfolded, can be lowered and raised at an angle in the form of a headrest. These types of sofas are often used as beds, that is, they are not folded in the morning.
4. Pantographs are the most complex mechanisms of "book" type sofas. There are several varieties of them. You can unfold the "Puma" sofa in one motion, without using rollers (which means that it is impossible to spoil the floor). The seat is pushed forward, the backrest is lowered, at the same time the legs of the support are lowered. You can fold everything back with the help of special handles. The pendulum device underlying the "walking eurobook" allows furniture to be transformed by simply pulling on the loop. To unfold the model with the tick-tock mechanism, it is enough to pull the seat towards you and slightly up and gently lower the structure to the floor.

Among the advantages of models equipped with a "pantograph" is the smoothest movement of the mechanism among the "books".

Roll-out structures

The roll-out mechanism means the presence of wheels. Part of the structure - two segments - in the folded state is inside the sofa. In order to spread out the furniture, it is necessary to roll out this half from the body, and then raise it flush with the seat. The quality of the videos is key.

Clamshells

The transformation of any "clamshell" occurs according to the principle of familiar furniture of the same name. The "French folding bed" in the unfolded state looks a bit like the Soviet model. You just need to stretch three sections forward, and it will stand on the metal supports hidden in the body. This is a lightweight, but quickly wearing mechanism, which can be mechanically damaged if the weight of the sleepers is too large.

Some of the problems were solved in the "American clamshell" model (sedaflex). It differs from the French one in that the transformer mechanism does not stretch out, namely, it unfolds according to the principle of a sandwich. First one section folds out, then another. Between them are supports. When installing sections on supports, a berth is obtained. This is one of the most convenient and reliable mechanisms for transforming sofas.

The main drawback of the "American clamshell" is the lack of a storage system. Inside the sofa is only a bed.

Accordion

In a way, this is also a clamshell. But if the latest types of transformation mechanisms hide additional sections in the lower part of a piece of furniture, then the “accordion” is in the back, which consists of two sections. For unfolding, it is necessary to push the lower part forward, and the back will decompose.

When folded, the "accordion" looks attractive and compact. And the absence of a mechanism at the bottom makes the sofa more reliable. Drawers for linen are not provided in the model, so it is often equipped with additional cabinets. The sleeping surface is flat, but its size is limited by the height of the back. Another significant drawback is the possibility of damage to the flooring during the transformation process.

Sofas equipped with a mechanism such as "accordion" are not very popular, so you won't be able to immediately find a model of a suitable color and size.

Folding sofas with metal frame

Models on a metal frame are more difficult to manufacture, more expensive. But if all the connecting nodes and mechanisms fit exactly, such sofas can last longer. The frame is based on shaped pipes, and the sofa cushions are placed on a metal mesh up to 0.5 cm thick. Due to the increased strength, such a frame is the most reliable for daily use.

Spartacus

"Spartak" is equipped with a mechanism that unfolds forward. The triple folding device is somewhat reminiscent of the "American clamshell", that is, it unfolds in three stages, standing on the supports inside the frame. An additional advantage is the presence of a polyurethane foam mattress and a metal mesh base, guaranteeing a comfortable sleep. Such elements are recommended by orthopedists for people who have problems with the musculoskeletal system.

In the Spartak models, not just a reliable transformation mechanism, such sofas are designed taking into account medical recommendations.

Elf

Sofas "Elf" with a metal frame have an orthopedic effect. An additional plus - models with a stepper mechanism increase the useful area of ​​\u200b\u200bthe bed due to the sections located at the bottom of the piece of furniture or in the back. And the "Elf" is laid out due to the armrests. They are bred on the sides - the design becomes longer. The frame is made of profiled pipes. The base for the pillows are curved wooden transverse slats.

The most complex and functional products

Sophisticated models of folding sofas are equipped with universal mechanisms and electronics that allow you to give the sleeping position the most comfortable position for a particular person. Among all types of folding furniture according to the type of transformation, the most multifunctional can be called the modification options "recliner". They are equipped with a control panel that allows you to fix the footrest at the required angle, push it out only a certain distance. The backrest angle is also adjustable. Recliners are supplied with vibration massagers. Smart models with electronics can remember settings. The disadvantages of recliners are obvious. They are expensive, in the event of a breakdown, repairs will also cost a round sum. In addition, this is more of a place to relax, not to sleep - there is no full-fledged sleeping surface.

Even a superficial acquaintance with what the sofa folding mechanisms are like leads to the conclusion that there are no universal tips for choosing. It all depends on many factors:

• housing conditions;
• frequency of use;
• financial opportunities;
• the required sleeping area.

It is definitely impossible to answer which sofa mechanism is better. Each has certain advantages and disadvantages. Simplicity of design can be a plus when it comes to constantly using an inexpensive mechanism. And a disadvantage if the main criterion is the comfort for sleep.

Expensive models equipped with an electric drive and a vibration massager will help you relax after a working day. But sleeping on them is hardly more comfortable than on a regular "book", which is much cheaper. In addition, the simple mechanism of the sofa is the most reliable, because there is nothing to break.

For regular sleep, it is better to choose a reliable and comfortable model of upholstered furniture. As a guest sofa, you can use a design that occupies a minimum of usable space.

In the store, you need to check the serviceability of the transformation mechanism. It should not make extraneous sounds or jam. To determine the quality of the assembly, you need to try to expand and fold the furniture several times.

Before giving preference to a particular model, it is worth deciding how exactly it will be used, prioritizing. Only then will it be possible to make an informed and reasonable choice. A wide range will allow you to purchase a product that meets all requirements.

The choice of sofa depends on living conditions and the frequency of use of the product.

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.
