Mechanisms for transforming sofas: which is better to choose
Everyone has the same idea of a good sofa - a beautiful design, a comfortable place to relax and sleep, operate without creaking, loss of functionality, subsidence for at least 10 years. To justify the expectation, you need to decide how often the back and seat will be converted into a bed. Accessories, mechanisms for transforming sofas affect the reliability of the design and the ease of changing positions. Devices differ in the principle of action, not everyone tolerates daily folding and regular loads.
By appointment, the furniture is conditionally divided into two types. Guest sofas serve to relax, receive guests, are rarely used as a bed. Special requirements are not imposed on transformation systems, but on design, seat depth, shape of backs and armrests. Frame, upholstery, fillers should provide comfort during rest, withstand heavy loads.
In a sofa for sleeping, it is important to choose the right mattress and transformation elements that will decompose the structure in seconds, will remain operational during daily use.
Before buying, you need to determine:
how often the berth will be laid out;
what space can be allocated for the sofa when unfolded;
Do you need boxes for bedding.
Types of transformation mechanisms by the principle of action
Manufacturers offer dozens of transformation elements, on which the ease and speed of conversion, the convenience of a berth, depend.
Common types of sofas:
A type
Features
1
Folding (tango, book)
Easy to use, with a minimum of mechanical elements, compact when unfolded, serve for a long time
2
Retractable (Conrad, Eurobook, Dolphin)
The entire seat or part extends, a wide bed forms. When transforming, you don’t need to make efforts, move the sofa away from the wall
3
Unfolding (American, Italian system, Spartak)
The mattress for sleeping is removed from under the seat, unfolds, and is installed on the legs. Unfolded sofa is comfortable, but takes up a lot of space
A detailed description of each mechanism will help you choose a sofa for specific conditions, needs and premises.
Eurobook
The design consists of a sliding part and a rear panel.During unfolding and assembly, the sofa does not need to be moved away from the wall and efforts are made. A sleeping place is created in two movements, even a child can handle the process. The seat is pushed forward, the back moves into the niche formed. When shifting, the rear part rises towards the wall, the seat is pushed all the way. Guides with roll rollers provide easy roll-out. Details are not deformed, do not wear out when laid out daily. In order not to scratch the floor, wheels or rubber pads are provided on the seat. After the transformation, a wide bed of two segments is formed with a small gap that can withstand two people of any complexion. Both halves are on the same level, do not cause inconvenience. Due to the wide seating area, the sofa is comfortable for sleeping one person undeveloped. All models come with large drawers that hold large items. Manufacturers offer eurobooks with a spring block, polyurethane foam of various stiffness, a frame made of metal or wood.
The folding speed and reliability of the design are high, the quality of the sleeping place is good, the disadvantage is the gap between the two halves.
Book
The first transformation mechanism for sofas has passed the test of time. Despite the small efforts when folding, the furniture is in demand due to the low price, compactness, roomy drawer. To create a sleeping place, the landing zone rises to a peculiar sound, which is heard when the mechanism is triggered. After the back rests perpendicular to the floor, the back is lowered. Of the two halves, an even wide bed is formed with a hollow in the middle. The performance of transformation elements depends on the quality of the metal and rivets. If the manufacturer used thin metal, the mechanism during regular use is deformed, wears out, the locking finger stops working.Folding locks are inexpensive, quickly changing to new ones. The rivets of the guide bar can be replaced independently.
Advantages of the book - low price, maintainability. The disadvantage is that when placing the sofa, you need to leave a small space near the wall for free folding or constantly push it away before the transformation.
Dolphin
The withdrawable system consists of a steel frame with polyurethane rollers, to which the rails are attached. The frame is sheathed with plywood or chipboard. Retractable sections are under the seat. The transformation mechanism was named for its resemblance to a jumping dolphin. The lower movable part is rolled out to the stop with a handle or loop. The section located inside after moving up and towards itself, as if jumping out of the bottom. Segments are easy to lift, difficulties arise only if the frames are made of low quality steel. But often the blocks do not match in height, the extendable part is more rigid than the seat. Only corner models are equipped with drawers.
When buying, check the thickness of the steel frame. "Dolphin" with thick mechanical plates, an anti-skew system, will delight you with a smooth ride, will last at least 10 years with daily folding / folding.
Roll-out sofa
In the body of the sofa with a stationary back, segments are hidden that roll forward and form a wide bed. The mechanism, located in place of the linen box, is driven by a strap attached to the lower block, and quickly and effortlessly unfolds. In the extendable part, a thin, not very comfortable for constant sleep sofa mattress. An additional storage system is equipped with only corner models. When buying, you need to consider that the design is not folding, the back is massive, only the armrests and side blocks are removed. To enter the room you need an opening of 0.8 m.
Sofas are available in two versions:
horizontal when assembled, take up more space, after transformation, the area increases by the width of one seat;
the perpendicular models assembled are short; when unfolding, two blocks are put forward.
Click-gag mechanism
The transformation system can be compared by the principle of work with the "book". The seat rises over the edge and reaches up to the sound of a second click. During lowering, the unit pulls the back. It turns out a good bed, without differences between the blocks, but with a small connecting seam in the middle. Unlike a regular “book”, the design provides for the possibility of incomplete analysis. After the first click, the sofa is set at an angle of 45 degrees to relax in a reclining position. With careful use, periodic lubrication, the click-gag lifting element will last 15 years. The couch combines high folding speed, durability of accessories, good quality berth. For sleep, it is recommended to choose models with spring mattresses or polyurethane foam with a density of 35 kg / m3.
Accordion
The transformation system consists of three parts, which when folding / unfolding move like bellows bellows. The sliding platform is lifted and extended onto itself, segments on wheels move forward until complete alignment. Models with automatic control are produced. The sleeping bed is designed for a weight of 160-180 kg; there are no height differences on the mattress on the mattress. To convert to a sitting position, the seat retracts from itself. Models with a solid wood case will withstand tough operation, it is better to purchase chipboard products as a guest option.
Advantages of the accordion sofas:
quick and easy folding;
most models have a small laundry section;
compactness, even in angular execution.
Less - to lay out the sofa and walk around the room, there should be plenty of space in front.
Tango
The basis of the design is a metal frame with orthopedic lattice. The principle of action of "tango" is the same as that of the "click-gag". The bed is made up of two soft blocks. When raising the seat up, the backrest lowers and fits onto the frame. To rest in a reclining position, the seat rises to the first click.
The main difference and design feature are raster armrests. They are individually regulated, occupy different positions after pressing, visually change the design of the sofa. A slightly angled armrest replaces the pillow. The design and mechanisms can withstand daily use, suitable for apartments with a limited area. For folding, you need to install the sofa at a distance of 15 cm from the wall.
Pantograph (tick-tack)
Due to the improved pendulum transformation mechanism, the pantograph is considered a good option for sleeping. The conversion to bed takes place in two stages. The lower segment is lifted by a hand strap and pushed forward, at this time the back is simultaneously lowered to the vacant seat. The folding block is held in a horizontal position by springs; loosening, creaking, and distortions are excluded. Transformation takes place along an arc on springs; structural elements do not touch the floor covering. The robust frame and accessories withstand a weight of about 220-240 kg.
Advantages of the pantograph system:
quick unfolding;
the floor is not damaged by rollers;
wide seat;
sofas are distinguished by a laconic design, but always come complete with original pillows.
The disadvantage is the high price.
French clamshell (mixotoyl)
The design consists of a frame and a soft block, under which there is a transformation system and a triple folded mattress. The mechanism is lifted by a handle; it is extended in two steps. Legs from a profile pipe independently fall to the floor. A monolithic berth with a base in the form of a mesh, lat or awning is formed.
The French clamshell has strengths and weaknesses:
pros
Minuses
1
Compact, space saving
Small length - 160 - 185 cm
2
Sleeping place without joints
Thin mattress - 6-10 cm
3
Wide seat
Mesh, awning sag over time
4
Does not damage the floor
In direct options there is no storage system
5
Low price
Folding mechanism wears out quickly during daily use
Evenly support the spine of the model with a base of bent glued lamellas and an awning.
Spartacus
The transformation system was developed by a furniture Russian-Italian company, by the principle of operation it is identical to the French folding bed. The sofa mechanism folded three times is lifted by a loop, which is located on the frame of the sliding part. To collapse the structure, the extreme part rises, the legs fold. The assembled system with the mattress is placed in a box. The length of the sleeping bed in Spartak has been increased to 190 cm. The frame of steel pipes and thick rods can withstand a weight of 220-240 kg. The coarse-mesh reinforced mesh does not bend under the weight of the body. The sofa is comfortable, reliable enough, easy to transform. But because of the thin mattress during sleep, transverse details are felt on the sections of the frame. The quality of the bed is insufficient for daily sleep.
Conrad or Telescope
The folding system is located under the seat, consists of three parts. When unfolding, the lower block rolls forward and pulls the next segment. The upper part of the soft back fits into a niche. All elements move easily and silently, withstand frequent transformations. A sofa with a deep seat looks a bit cumbersome, the place to sleep is at a height of 45 cm. For comfort, “Konrad” with a block of independent springs is not inferior to a bed, the design has no weak links. Sofas are available in angular and straight form, suitable for the hall, bedroom.
Advantages of designs with a telescopic mechanism:
high folding speed;
most models have a storage system;
steady and strong framework.
Sedaflex - American clamshell
The design resembles a two-folding folding bed with a reinforced frame. The mattress is fixed on a suspension, which consists of lamellas, mesh, elastic belts. This combination provides a comfortable surface for sleeping and lying down. On the retractable base, the height of the head is adjusted. During folding, the section emerges from a niche, moves forward, and is mounted on steel legs. The kit includes a mattress made of PPU with a height of 10-14 cm or spring blocks. The assembly-disassembly process takes place in the air, the legs of the extension do not scratch the floor. The transformation mechanism wears out slowly; rivets and lamellas sometimes break. Spare parts can be bought at the store and repair the base yourself. A full-fledged berth is created quickly and quietly, suitable for people with heavy weight, and can be used daily.
Elf
The sofa meets the requirements for a bedroom place.
The frame of profiled pipes and lamellas provide a flat surface.
Large items can be accommodated in the deep and high linen box.
The berth is extended by armrests, which are installed in various positions.
Highly elastic flooring does not sag during heavy use.
Wheels with polyurethane coating do not leave scuffs and scratches on the floor.
Armrests when folded and unfolded can withstand a weight of 40 kg. But it is not recommended to sit on them, jump.
Cougar
The transformation mechanism is designed for daily use. In combination with a solid frame, a spring unit guarantees 10 years of service without jamming when extending elements. When folded, the segments are under each other. For unfolding, the front mat rises, moves forward, and is mounted on a sliding support. The second half fits into the vacant niche.A 45 cm wide bed is created without a gap between the parts. The synchronizing telescopic device promotes coordination and smooth movement, tight joining of the halves at the same level. The sofa will save space in a small room, but direct models do not have a storage system.
Recliner
The mechanism creates the conditions for relieving muscle tension, adjusts the backrest at different angles, extends the footrest. The modules move independently of each other, each sitting can adjust the place to their needs. The back falls after pressing, returns to the initial position with the lever. Luxury sofas are equipped with an electric drive, all functions are activated by the remote control. The furniture is not designed for sleeping, but after folding the back, you can sleep on it. Recliner sofa is located in the lounge or reception area. The price of products is high, even with standard options.
Transformer
Transforming models are designed to save space. In IKEA you can find a wardrobe bed, complemented by shelves and a table, or bunk convertible sofas. Variable furniture is difficult to fold, but in small rooms it is impossible to place all the necessary items in a different way. A 3-in-1 convertible sofa is suitable for a hall, a guest or a children's room. Blum lifting systems and accessories work flawlessly, simplify access to the upper tier, rollback, quick assembly. In disassembled form, two berths are formed at the bottom and one at the top. Separate blocks of transforming sofas form a sleeping bed of the required size, are combined in any order, and are used separately. The main advantage of transforming structures is the replacement of 2-3 pieces of furniture. The disadvantage is that complex mechanisms are expensive.
Cheburashka
A simple and reliable sofa mechanism is translated into the position of the bed without noise, moving upwards and towards yourself. After deployment, the parts are mounted on steel supports.When folding, two sections are hidden under the seat. The transformation mechanism with frequent use does not leave rolled tracks on the floor. Convenience is provided by a flexible metal frame with a latte base and a thick layer of medium hardness filler. Furniture foam is immune to bending, does not exfoliate, and can withstand daily loads. The berth is designed for height 190 cm and weight 200 kg.
Advantages of the Cheburashka retractable system:
reliability;
small folded sizes;
flat berth, which does not sag over time;
low price.
Cons - the lack of a linen container.
Automatic gear
All actions to create a place for sleeping are performed by the electric drive after pressing the button on the remote control. The block located under the seat straightens and rolls forward in a few seconds, unfolds without distortions. Such a convenient option has a too high price, but it is justified by the long service life. Transformation mechanisms for electric sofas are made of high-strength materials, equipped with a base and a mattress with orthopedic properties. The design provides a lever in case of a power outage. After unlocking the furniture is laid out manually. In some models with automation, the relaxation position, massage devices, leg supports, adjustable head restraints are provided.
Unfolding sofa
The sleeping place is hidden in the body and moves on rollers fixed to the sofa frame. To convert to a bed, you need to pull the belt on the front of the seat. Blocks are removed without the application of physical force; they are laid immediately on the floor without backups. In the roll out half, there may be a laundry box with a durable lid, which serves as a berth. A folded double mattress is thrown back from the seat.
The simplest, most convenient and cheapest transformation has disadvantages:
low place for sleep, is at a level from the floor only 25-30 cm;
the mattress is thin, on the unfolded part it is softer to sleep than on the frame, the halves are scattered on the floor.
Swivel mechanism
The berth is formed by displacement of the movable part. She drives off to the side, adjoins the corner block of the structure, the wheels are fixed. The process takes place without complex manipulations, thanks to a smoothly sliding roller. So that the resulting bed does not move apart, a hook is provided that holds two blocks nearby.
Benefits:
spacious place with a flat surface;
in the design there are no small elements prone to breakage;
rotary transformation mechanism combined with orthopedic base;
one or two laundry boxes.
Disadvantages: high cost.
Lit
A single small-sized sofa with a wide seat is extended due to the armrests. The side parts rise to the stop and bend outward. Armrests can take a fully horizontal position, be at a certain angle. The model is suitable for a children's room, grows with a child. With two armrests spread out, the seat lengthens up to 200 cm.
Advantages of the Lit transformation mechanism:
compactness;
comfortable berth of medium hardness;
the ability to fix the armrests in 3 positions;
capacious box for a bed or toys.
How to choose a sofa by type of transformation
Before buying, you need to consider the size of the room, the number of family members, how much the layout mechanism is up to them. A small area in a disassembled form is occupied by a book, a eurobook. The folding systems are reliable, time-tested, require little effort, but intuitively, rarely break. The improved click-gag mechanism is easier to transform, is brought into half-sitting mode, but is more vulnerable. The furniture makers earned good marks from pantograph and accordion transformation mechanisms.In folding beds, frame parts are often deformed, it is better to use them as a guest option. For a child, a teenager, one person, designs with folding armrests are suitable. When assembled, the length of the couch is 1.6 m, after transformation 20 cm is added to each side part. People who have back problems should take a closer look at the reliners.
Which sofa to choose for sleep?
The sofa, which will be used as a bed, must be transformed without noticeable efforts, create a fairly rigid sleeping place with a width of at least 140 cm. Folding and extendable structures are most adapted to daily transformations. Reliable direct "books" are a bit short in width. A spacious bed is formed by angular models. Sofas are released with a different base under the mattress. It is recommended to choose a “snake” block or elastic arcuate armor, providing a springy effect. Strength and durability of furniture depends on the frame. The frames of wood, multilayer plywood, metal withstand intense loads.
Sofa: with or without springs
Filler affects good sleep, well-being, health. On too hard or soft, a falling place, the spinal column is bent. Good support to all parts of the body is provided by spring blocks. They evenly take the load from the body, retain properties for a long time, and are recommended for people with high weight.
High-quality porous materials, polyester fibers, latex dampen vibration, resist stress, quickly restore shape, and support the body well. It is quickly deformed, soft foam rubber lays, the synthetic winterizer loses its shape.
Which is better?
It is impossible to answer unequivocally which internal content is better. Each material has its own characteristics.

As the reviews show, if you choose the transformation mechanism correctly, the sofa will not disappoint, it will last a long time. Rollout and folding systems are considered the most reliable. They respond well to the accordion system, which forms a berth comparable to an orthopedic bed. Among the cots, a sedaflex is distinguished, which attracts with a thick mattress and a non-sagging base. No less popular are modular designs for living rooms. With built-in cupboards, shelves. Owners of small apartments recommend 3 in 1 transformers, replacing a sofa, table and bed.
Conclusion
Transforming sofas do not need a colorful description, because with some shortcomings they are the only possible option for a room of 8 square meters. m. Longitudinal models without transverse seams are usually bought for sleep. Corner sofas are suitable for large families, zoning space, reception. Built-in storage system will save you from the trouble of finding a place for bedding, seasonal items.The choice of sofas with transformation mechanisms is large, ask questions before buying, lay out the structure, evaluate the height and rigidity of the mattress, or see the characteristics indicated in the documents.
Everyone has the same idea of a good sofa - a beautiful design, a comfortable place to relax and sleep, operate without creaking, loss of functionality, subsidence for at least 10 years. To justify the expectation, you need to decide how often the back and seat will be converted into a bed.

How to choose a sofa: basic criteria
By appointment, the furniture is conditionally divided into two types. Guest sofas serve to relax, receive guests, are rarely used as a bed. Special requirements are not imposed on transformation systems, but on design, seat depth, shape of backs and armrests. Frame, upholstery, fillers should provide comfort during rest, withstand heavy loads.

Types of transformation mechanisms by the principle of action
Manufacturers offer dozens of transformation elements, on which the ease and speed of conversion, the convenience of a berth, depend.
Common types of sofas:
A detailed description of each mechanism will help you choose a sofa for specific conditions, needs and premises.
Eurobook
The design consists of a sliding part and a rear panel.During unfolding and assembly, the sofa does not need to be moved away from the wall and efforts are made. A sleeping place is created in two movements, even a child can handle the process. The seat is pushed forward, the back moves into the niche formed. When shifting, the rear part rises towards the wall, the seat is pushed all the way. Guides with roll rollers provide easy roll-out. Details are not deformed, do not wear out when laid out daily. In order not to scratch the floor, wheels or rubber pads are provided on the seat. After the transformation, a wide bed of two segments is formed with a small gap that can withstand two people of any complexion. Both halves are on the same level, do not cause inconvenience. Due to the wide seating area, the sofa is comfortable for sleeping one person undeveloped. All models come with large drawers that hold large items. Manufacturers offer eurobooks with a spring block, polyurethane foam of various stiffness, a frame made of metal or wood.
Book
The first transformation mechanism for sofas has passed the test of time. Despite the small efforts when folding, the furniture is in demand due to the low price, compactness, roomy drawer. To create a sleeping place, the landing zone rises to a peculiar sound, which is heard when the mechanism is triggered. After the back rests perpendicular to the floor, the back is lowered. Of the two halves, an even wide bed is formed with a hollow in the middle. The performance of transformation elements depends on the quality of the metal and rivets. If the manufacturer used thin metal, the mechanism during regular use is deformed, wears out, the locking finger stops working.Folding locks are inexpensive, quickly changing to new ones. The rivets of the guide bar can be replaced independently.
Advantages of the book - low price, maintainability. The disadvantage is that when placing the sofa, you need to leave a small space near the wall for free folding or constantly push it away before the transformation.
Dolphin
The withdrawable system consists of a steel frame with polyurethane rollers, to which the rails are attached. The frame is sheathed with plywood or chipboard. Retractable sections are under the seat. The transformation mechanism was named for its resemblance to a jumping dolphin. The lower movable part is rolled out to the stop with a handle or loop. The section located inside after moving up and towards itself, as if jumping out of the bottom. Segments are easy to lift, difficulties arise only if the frames are made of low quality steel. But often the blocks do not match in height, the extendable part is more rigid than the seat. Only corner models are equipped with drawers.
Roll-out sofa
In the body of the sofa with a stationary back, segments are hidden that roll forward and form a wide bed. The mechanism, located in place of the linen box, is driven by a strap attached to the lower block, and quickly and effortlessly unfolds. In the extendable part, a thin, not very comfortable for constant sleep sofa mattress. An additional storage system is equipped with only corner models. When buying, you need to consider that the design is not folding, the back is massive, only the armrests and side blocks are removed. To enter the room you need an opening of 0.8 m.
Sofas are available in two versions:
Click-gag mechanism
The transformation system can be compared by the principle of work with the "book". The seat rises over the edge and reaches up to the sound of a second click. During lowering, the unit pulls the back. It turns out a good bed, without differences between the blocks, but with a small connecting seam in the middle. Unlike a regular “book”, the design provides for the possibility of incomplete analysis. After the first click, the sofa is set at an angle of 45 degrees to relax in a reclining position. With careful use, periodic lubrication, the click-gag lifting element will last 15 years. The couch combines high folding speed, durability of accessories, good quality berth. For sleep, it is recommended to choose models with spring mattresses or polyurethane foam with a density of 35 kg / m3.
Accordion
The transformation system consists of three parts, which when folding / unfolding move like bellows bellows. The sliding platform is lifted and extended onto itself, segments on wheels move forward until complete alignment. Models with automatic control are produced. The sleeping bed is designed for a weight of 160-180 kg; there are no height differences on the mattress on the mattress. To convert to a sitting position, the seat retracts from itself. Models with a solid wood case will withstand tough operation, it is better to purchase chipboard products as a guest option.
Advantages of the accordion sofas:
Less - to lay out the sofa and walk around the room, there should be plenty of space in front.
Tango
The basis of the design is a metal frame with orthopedic lattice. The principle of action of "tango" is the same as that of the "click-gag". The bed is made up of two soft blocks. When raising the seat up, the backrest lowers and fits onto the frame. To rest in a reclining position, the seat rises to the first click.
The main difference and design feature are raster armrests. They are individually regulated, occupy different positions after pressing, visually change the design of the sofa. A slightly angled armrest replaces the pillow. The design and mechanisms can withstand daily use, suitable for apartments with a limited area. For folding, you need to install the sofa at a distance of 15 cm from the wall.
Pantograph (tick-tack)
Due to the improved pendulum transformation mechanism, the pantograph is considered a good option for sleeping. The conversion to bed takes place in two stages. The lower segment is lifted by a hand strap and pushed forward, at this time the back is simultaneously lowered to the vacant seat. The folding block is held in a horizontal position by springs; loosening, creaking, and distortions are excluded. Transformation takes place along an arc on springs; structural elements do not touch the floor covering. The robust frame and accessories withstand a weight of about 220-240 kg.
Advantages of the pantograph system:
The disadvantage is the high price.
French clamshell (mixotoyl)
The design consists of a frame and a soft block, under which there is a transformation system and a triple folded mattress. The mechanism is lifted by a handle; it is extended in two steps. Legs from a profile pipe independently fall to the floor. A monolithic berth with a base in the form of a mesh, lat or awning is formed.
The French clamshell has strengths and weaknesses:
Spartacus

The sofa mechanism folded three times is lifted by a loop, which is located on the frame of the sliding part. To collapse the structure, the extreme part rises, the legs fold. The assembled system with the mattress is placed in a box. The length of the sleeping bed in Spartak has been increased to 190 cm. The frame of steel pipes and thick rods can withstand a weight of 220-240 kg. The coarse-mesh reinforced mesh does not bend under the weight of the body. The sofa is comfortable, reliable enough, easy to transform. But because of the thin mattress during sleep, transverse details are felt on the sections of the frame. The quality of the bed is insufficient for daily sleep.
Conrad or Telescope
The folding system is located under the seat, consists of three parts. When unfolding, the lower block rolls forward and pulls the next segment. The upper part of the soft back fits into a niche. All elements move easily and silently, withstand frequent transformations. A sofa with a deep seat looks a bit cumbersome, the place to sleep is at a height of 45 cm. For comfort, “Konrad” with a block of independent springs is not inferior to a bed, the design has no weak links. Sofas are available in angular and straight form, suitable for the hall, bedroom.
Advantages of designs with a telescopic mechanism:
Sedaflex - American clamshell
The design resembles a two-folding folding bed with a reinforced frame. The mattress is fixed on a suspension, which consists of lamellas, mesh, elastic belts. This combination provides a comfortable surface for sleeping and lying down. On the retractable base, the height of the head is adjusted. During folding, the section emerges from a niche, moves forward, and is mounted on steel legs. The kit includes a mattress made of PPU with a height of 10-14 cm or spring blocks. The assembly-disassembly process takes place in the air, the legs of the extension do not scratch the floor. The transformation mechanism wears out slowly; rivets and lamellas sometimes break. Spare parts can be bought at the store and repair the base yourself. A full-fledged berth is created quickly and quietly, suitable for people with heavy weight, and can be used daily.

The second half fits into the vacant niche.A 45 cm wide bed is created without a gap between the parts. The synchronizing telescopic device promotes coordination and smooth movement, tight joining of the halves at the same level. The sofa will save space in a small room, but direct models do not have a storage system.
Recliner
The mechanism creates the conditions for relieving muscle tension, adjusts the backrest at different angles, extends the footrest. The modules move independently of each other, each sitting can adjust the place to their needs. The back falls after pressing, returns to the initial position with the lever. Luxury sofas are equipped with an electric drive, all functions are activated by the remote control. The furniture is not designed for sleeping, but after folding the back, you can sleep on it. Recliner sofa is located in the lounge or reception area. The price of products is high, even with standard options.

Cheburashka
A simple and reliable sofa mechanism is translated into the position of the bed without noise, moving upwards and towards yourself. After deployment, the parts are mounted on steel supports.When folding, two sections are hidden under the seat. The transformation mechanism with frequent use does not leave rolled tracks on the floor. Convenience is provided by a flexible metal frame with a latte base and a thick layer of medium hardness filler. Furniture foam is immune to bending, does not exfoliate, and can withstand daily loads. The berth is designed for height 190 cm and weight 200 kg.
Advantages of the Cheburashka retractable system:
Cons - the lack of a linen container.
Automatic gear
All actions to create a place for sleeping are performed by the electric drive after pressing the button on the remote control. The block located under the seat straightens and rolls forward in a few seconds, unfolds without distortions.

Blocks are removed without the application of physical force; they are laid immediately on the floor without backups. In the roll out half, there may be a laundry box with a durable lid, which serves as a berth. A folded double mattress is thrown back from the seat.
The simplest, most convenient and cheapest transformation has disadvantages:
Swivel mechanism
The berth is formed by displacement of the movable part. She drives off to the side, adjoins the corner block of the structure, the wheels are fixed.

How to choose a sofa by type of transformation
Before buying, you need to consider the size of the room, the number of family members, how much the layout mechanism is up to them.

Sofas are released with a different base under the mattress. It is recommended to choose a “snake” block or elastic arcuate armor, providing a springy effect. Strength and durability of furniture depends on the frame. The frames of wood, multilayer plywood, metal withstand intense loads.
Sofa: with or without springs
