Types of transformations of folding sofas. Sofa transformation mechanisms

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.

A cozy living room is rarely complete without upholstered furniture. To choose a product that will bring comfort and warmth, you need to know what types of sofas exist. After all, they play an important role and are a place not only for relaxation, but also for playing with children or talking with guests. Basically, the differences are in the principle of unfolding sofas, the structure and color of the upholstery and in their design.

A cozy living room is rarely complete without upholstered furniture.

Currently, a huge number of designs and types of upholstered furniture has been developed and presented for sale. In such a variety, it is difficult for people to figure out which ones are better and decide on the choice of a sofa that is right for them. Often, buyers are based on the appearance and upholstery material of the purchased piece of furniture. But these indicators are important only when it is used infrequently. If you put a beautiful leather model in your office or living room as an additional element of the interior. For the same purposes, there are monolithic sofas, that is, non-folding ones, they can often be seen in public places.

But it is a completely different matter if the purchase of a sofa is made for use for every day and preferably not for 1 year. Usually in this case it is assumed that he will be laid out daily for sleep. In order not to make a mistake with the choice, it is important to know what are the mechanisms for transforming sofas. It is necessary to find out other features of such furniture, the required dimensions of free space, ease of unfolding, the presence of a department for linen, and decide which types of sofas are better.

Currently, a huge number of designs and types of upholstered furniture have been developed and presented for sale.

All modern models can be divided according to the following criteria:

• type of folding mechanism;
• structural features;
• purpose functions;
• overall size and number of seats.

Description of types of transformation mechanisms

The mechanism for transforming folding sofas is selected depending on its strength and frequency of use. The main types of folding mechanisms for sofas can be concluded in the following list:

• a book, this also includes “eurobook” and “click-clack”;
• folding bed - French or American;
• accordion;
• roll-out mechanism;
• scissors;
• dolphin.

Types of book type sofa mechanisms are the most famous and common. Their reliability has been tested by time. Enhanced with new technologies and unfolding in just one motion, the click-clack sofa is easy to use even for teenagers. Usually such furniture has a drawer for folding bedding. Sofa-books are moved apart by raising the horizontal surface until it clicks, after which the back is lowered. The inconvenience of such a mechanism is that you have to move the furniture away from the wall. "Eurobook" differs only in that the seat is shifted, making room for the back, so you do not need to move the sofa.

The mechanism of transformation in the form of a clamshell resembles the object of the same name. The seat unfolds in length and rests on retractable legs. The American and French versions differ only in that the former is more durable, frequent decomposition is suitable for it.

The transformation mechanism of folding sofas is selected depending on its strength and frequency of use.

The next type is called the accordion. When laying out such a sofa, one can notice a similarity with the principle of stretching furs. Accordion sofas are durable due to their simple design and are very popular. Although they require sufficient space in front of them, they are simple and easy to use. The back of the accordion sofa combines 2/3 of the bed at once, and modern sofa designs have removable covers, which makes it easier to care for them. Other advantages of furniture with an accordion type mechanism are their compactness when assembled and the rather large size of the unfolded bed.

The roll-out mechanism is the simplest and most reliable. Under the seat is the middle part of the sleeping area, which, when unfolded, extends behind it. The disadvantages of this furniture is that during operation there is a possibility of damaging the floor, and the bed is located somewhat lower than that of other models.

Pieces of furniture with a scissors mechanism are a novelty. When transformed, such a sofa turns into a comfortable double bed with a luxurious headboard and bedside tables on the sides. The seat halves move like scissors.

The sofa dolphin consists of 2 parts. This transformation mechanism is suitable for corner structures. When unfolded, the movement of the additional element resembles the jump of a dolphin emerging from the water. Under a lateral part the box for linen is located. The sleeping place is large and has a flat surface.

Types of sofas by shape, design and purpose

The choice of a sofa is based on the personal preferences of each person. Any kind of this piece of furniture has its undeniable advantages and is able to take its rightful place in the house. Types of sofas by design differ in classic straight lines, comfortable corner, modular and island.

Straight models are classics. Their main plus is that you can choose the appropriate dimensions that correspond to the size of the room. They can be with or without armrests, transforming or stationary.

Straight models are a classic

Corner upholstered furniture has gained a certain popularity among the population. Very comfortable and functional, they can be installed in any room. When choosing such a model, the question may arise of how to disassemble a corner sofa if you need to rearrange it to the other side of the room. In such a case, many models provide the possibility of reinstalling the corner part. The sides of this sofa can be different or the same in length.

Modular furniture is made collapsible and can, like a designer, change at the request of the owner. It will eliminate the need to buy a new one in case of moving, as the modular sofa can be easily reconfigured to suit different room shapes. This is a great option for rest rooms with a home theater.

Island models are initially rounded and are designed to take place in the center of spacious rooms. They are able to form a unique interior, because they create a soft cozy island in the room. Their unusual shape is often successfully complemented by other pieces of furniture.

Sofas of various shapes can be designed for an office or a living room, a kitchen or a children's room. In different situations, you need to seriously approach the choice. For children's furniture, bright colored upholstery is needed, and an easy-to-use transformation mechanism, no sharp or protruding parts.

According to the number of seats, sofas can be compact, designed for 2-3 people, or almost gigantic, which can accommodate a large company. But large models must be bought with caution, after measuring the room and making sure that the exit or balcony door is not blocked.

Transportation principles

Upholstered furniture is very comfortable for relaxing, but it will take a lot of effort to move it. When buying a sofa or moving, transportation is an important and responsible step, so in order to avoid mistakes and keep the furniture in working order, you need to follow certain rules. A good option is to hire specialists for transportation, who will quickly and professionally deal with this. But if funds do not allow, you need to rely only on your own strength.

Narrow doorways and corridors will only allow you to carry a disassembled sofa. Therefore, it will need to be disassembled, and then assembled in a new place. For this, the assembly diagram of this model, which is always attached to the purchased furniture, is useful. But if the purchase was a long time ago, and all the instructions are lost, you will need to disassemble the sofa, marking every detail, and, if possible, photographing the process.

Carefully wrap all parts in bubble wrap and carefully place them in the trunk of your car or van. To easily transport a disassembled sofa in a spacious van, you need to secure the parts so that they cannot move around the car. After transporting and unpacking furniture, you should not postpone its assembly for a long time.

The sofa is a noticeable and impressive piece of furniture in the house, which should bring comfort and coziness.

Conclusion

When purchasing upholstered furniture, you need to pay special attention to how the sofa unfolds and what mechanism is used in it. It must match the expected load. The service life and usability of the sofa will depend on this. You should not buy upholstered furniture just because you liked the color or your friends bought the same. After all, the sofa is a noticeable and impressive piece of furniture in the house, which should bring comfort and coziness.

Attention, only TODAY!

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.

• 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 is activated, and then lowered by pressing on the edge to fold the back, and slide in.

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.

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;
• reliability;
• ease of use;
• can be used frequently without the risk of breakage and wear.

• has only two positions - lying and sitting;
• the inability to move the sofa tightly against the wall.

Tango

"Tango" is the prototype of a sofa folding system called "click-clack". Many manufacturers seek to simply surprise the buyer with a beautiful new term. In general, this system is very much like a classic "book". There is only one difference - when unfolding, such a sofa can also take intermediate positions, and not just “sitting-lying”. The backrest can be adjusted to a comfortable level. These sofas are equipped with a bed storage box.

• fixation of the back in several positions;
• compact size;
• when unfolded, the sofa creates a surface without bumps.

Minus - you can not attach the back tightly to the wall.

Eurobook

Such a mechanism for unfolding classic sofas, like the Eurobook, is easy to identify by pushing the seat forward on roll-out rollers. In this case, a niche is formed in which a part of the sofa, which previously served as the back, fits.

• ease of converting the sofa into a bed;
• reliability of the mechanism;
• plenty of space to sleep;
• large niches for storage.

Minus — due to excessively large seats on the sofa, people with small stature and children will not feel comfortable, because they will not be able to lean on the back.

Dolphin

This is the most popular mechanism for transforming corner sofas. To unfold it, you need to pull the loops attached to the section under the seat. The movement should be up and towards you. The section will roll out and stand next to the seat, forming a large bed. The laundry box is located in the non-roll-out part of the seat.

Note: The dolphin mechanism exerts a heavy load on the sofa body, so you need to make sure that it is made of high-quality wood.

• comfortable bed;
• simplicity and ease of deployment.

Minus - not very long service life with the active use of the mechanism.

Pantograph

These types of folding sofas can often be found under the name "puma" or "tic-tac". This system arose as a variant of the Eurobook, only without roll-out rollers. Inside there is a spacious bed box.

To transform this sofa, you need to pull up the seat of the sofa, grabbing its edge in the middle. With this movement, you will activate the mechanism that pushes the seat up and forward and opens the legs of the support. In the resulting niche, lay the back-pillow.

• comfortable place to sleep;
• easy folding mechanism;
• does not spoil the floor covering with rollers.

Minuses:

• the mechanism is expensive;
• very wide seat.

The sleeping surface of such a sofa is represented by three sections. To straighten them into a plane, you just need to pull the edge of the seat. For frequent use as a bed, such furniture is not recommended, since these types of sofa folding mechanisms wear out very quickly.

Tip: For unfolding, you need to take care of the presence of a fairly large space.

Plus - when assembled, this sofa is very compact.

Minuses:

• the sleeping surface has irregularities;
• short service life.

Roll-out sofa

• very durable and reliable mechanism;
• comfortable place to sleep;
• compact dimensions when assembled.

Minuses:

• roll-out rollers can scratch the flooring when unfolding;
• low bed.

Accordion

"Accordion" got its name for some resemblance to the musical instrument of the same name. The sleeping space of the sofa stretches in a peculiar way, moving forward at the moment of unfolding, and then rests on the extended mobile legs. When folded, such a sofa has compact dimensions, but more space is required for transformation. The storage compartment is located in the back of the sofa.

• reliable and stable mechanism;
• long service life of the sofa;
• ease of transformation.

Minuses:

• there is no built-in place for linen;
• draw-out type of mechanism can cause scratches on the flooring.

Spartacus

To transform such a sofa into a comfortable place to sleep, you need to pull the seat so that it decomposes in three steps and stands on extended legs. This type of folding sofas was jointly developed by Russian and Italian craftsmen. Such furniture is very well suited for sleeping. The design of the mechanism provides a long berth. In fact, this is a more durable French clamshell, complemented by a welded metal grill.

• strength and durability of the mechanism;
• ease of use;
• as a bed can be used often;
• comfortable sleeping place.

Minuses:

• there is no place to store the bed;
• before unfolding the sofa, you need to remove it from it.

Note: There is also a mechanism for laying out Ifagrid sofas, which is similar to Spartak, but also has some differences.

Conrad or Telescope

To expand such a sofa, you need to pull on its lower part. The sections will roll out one after the other, like a telescope, and stand on the supports.

This type of furniture differs from classic roll-out sofas by the large height of the bed.

• reliable mechanism;
• can be used daily;
• compact volume;
• there is a box for linen;
• sleep comfortably.

Minus - the sofa is very heavy due to the massive mechanism.

Sedaflex (American folding bed)

• very strong mechanism;
• compact;
• has a quality .

Minuses:

• no storage box.

Elf

This is a sofa with a swivel transformation mechanism. The armrests at the time of the transformation of the bed are bred to the sides, and a comfortable place to sleep is obtained. The armrests in this sofa can be adjusted in height and have several positions.

• compact model;
• comfortable bed;
• due to the use of lamellas, an orthopedic effect is obtained;
• Armrests can be adjusted to suit individual needs.

Minuses:

• the sofa cannot be leaned close to the wall;
• the bed is located in the same place as the seat.

The name of this type of mechanism comes from the English "recline" - to lean back. The transformation takes place thanks to complex mechanisms hiding in the depths of the sofa. With their help, you can adjust the inclination of the backrest and push the footrest to the desired position. In some models, there are also special pillows with vibration massage. The most expensive models are equipped with an electric motor that is controlled by a remote control.

Pros:

• ease of management;
• you can adjust the sofa to the needs of your body;
• comfort in any position.

• very high cost;
• you can only sit, because there is no position for sleeping.

Sofa with unfolding on the floor

• small dimensions when folded;
• the cheapest type of folding sofas.

• not a very comfortable bed;
• there is no area for storing bedding.

What to choose?

As a result, you can determine which of the sofa folding mechanisms has become the best in its category:

• eurobook - the most reliable mechanism;
• tango is the most comfortable to sit on;
• dolphin - the most spacious;
• pantograph, accordion and roll-out - the most comfortable for sleeping;
• tango, eurobook and roll-out - have special storage compartments;
• roll-out and elf - the most compact;
• The book is the most affordable.

When buying any sofa, be sure to inspect its folding mechanism, consult the seller about this, ask questions and demand answers to them. The service life of the sofa and the convenience of its use depend very much on the correct mechanism. If the sofa will rarely be laid out, then you should pay attention to compact models, but not intended for frequent transformation.

tweet

• 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 the weight along the trajectory of a semicircle 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 floor covering.

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.
