Mechanisms for the transformation of sofas: which one is better to choose

The idea of ​​a good sofa is the same for everyone - a beautiful design, a comfortable place to rest and sleep, operation without squeak, loss of functionality, subsidence for at least 10 years. To meet the expectations, you need to decide how often the back and the seat will be transformed into a bed. Fittings, transformation mechanisms of sofas affect the reliability of the design and ease of changing positions. Adaptations differ in the principle of action, not everyone can tolerate daily unfolding and regular loads.

How to choose a sofa: the main criteria

By appointment, the furniture is conventionally divided into two types. Guest sofas are used for recreation, reception of guests, rarely used as a bed. Special requirements are imposed not on the transformation systems, but on the design, the depth of the seats, the shape of the backs and armrests. The frame, upholstery, fillers should provide comfort during rest, withstand heavy loads.

In the sofa for sleeping, it is important to choose the right mattress and transformational elements, which will decompose the structure in seconds, will remain operational with daily use.

Before buying you need to determine:

• how often the bed will be laid out;
• what space can be allocated for the sofa in the unfolded form;
• whether boxes for bedding are necessary.

Types of transformation mechanisms based on the principle of action

Manufacturers offer dozens of transformational elements on which the ease and speed of transformation, the convenience of a sleeping place, depend.

Common types of sofas:

A detailed description of each mechanism will help to choose a sofa for specific conditions, needs and premises.

Eurobook

The design consists of a sliding part and a rear panel. During the folding and assembly of the sofa does not need to move away from the wall, and make an effort. The berth is created by two movements, even a child can cope with the process. Sitting moves forward, the back moves to the formed niche. When moving the back part rises towards the wall, the seat moves to the stop. Easy roll-out is provided by guides with rolling rollers. Details are not deformed, do not wear out during daily unfolding. In order not to scratch the floor, there are wheels or rubber pads on the seat. After the transformation, a wide bed of two segments is formed with a small gap that will stand two people of any build. Both halves are on the same level, do not cause inconvenience. Due to the wide seat sofa is convenient for one person to sleep in nerazlozhennom form. All models are available with large drawers that accommodate large items. Manufacturers offer eurobooks with spring block, polyurethane foam of various rigidity, metal or wood frame.

The folding speed and reliability of the design are high, the quality of the place to sleep 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 in folding, furniture is in demand due to the low price, compactness, roomy box. To create a berth, the landing zone rises to a peculiar sound, which is heard when the mechanism is triggered. After the back part lies perpendicular to the floor, the back is lowered. An even wide bed with a hollow in the middle is formed from the two halves. The operability of the transformation elements depends on the quality of the metal and the rivets. If the manufacturer used thin metal, the mechanism is deformed, worn out and regularly used; the locking pin stops working. Adding 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 against the wall for free unfolding or constantly move it back before transformation.

Dolphin

The withdrawable system consists of a steel frame with polyurethane rollers, to which the guides 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 moving part rolls out against the stop with the help of a handle or a hinge. The section inside after moving up and towards itself, as if jumps out of the bottom. Segments easily rise, difficulties arise only if the frames are made of low-grade steel. But often the blocks do not coincide in height, the retractable part is more rigid than the seat. Extendable boxes are equipped only with corner models.

When buying, check the thickness of the steel frame. "Dolphin" with thick mechanical plates, anti-perekos system, will delight in a smooth ride, will last at least 10 years with daily folding / folding.

Roll out sofa

In the case of a sofa with a stationary back, there are hidden segments that roll out forward and form a wide bed. The mechanism, located on the site of the laundry box, is activated by a strap attached to the lower unit, and quickly and effortlessly unfolds. In the extended part of the thin, not very comfortable for constant sleep sofa mattress. The additional storage system is equipped only with corner models. When buying, you need to consider that the construction is not collapsible, the back is massive, only the armrests and side blocks are removed. For skidding in the room 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 in assembled form are short; two blocks are put forward when unfolding.

Click-flick mechanism

The system of transformation can be compared on the principle of working with the "book". The seat rises over the edge and stretches up to the sound of a second click. During lowering, the unit pulls back. It turns out a good bed, without differences between the blocks, but with a small docking seam in the middle. In contrast to the usual "book" in the design provides the possibility of incomplete analysis. After the first click the sofa is set at an angle of 45 degrees to relax in a reclining posture. With careful operation, periodic lubrication lift element "click-klyak" will last 15 years. The couch combines high folding speed, durability of fittings, good quality of a 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 folded / unfolded, move like accordion bellows. The extendable platform is lifted and pulled out towards itself, the segments on the wheels are moved forward to 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 interfering with sleep on the mattress. To transform into a sitting position, the seat retracts from itself. Models with solid wood hull will withstand tough use, products made of chipboard is better to purchase as a guest option.

Advantages of sofas "accordion":

• quick and easy folding;
• most models have a small laundry section;
• compact, even angled.

Minus - in order to expand the sofa and walk around the room, there must be a lot of space in front.

Tango

The basis of the design is a metal frame with an orthopedic lattice. The principle of "tango", the same as in "click-klyak". The bed is formed of two soft blocks. When raising the seat up, the back is lowered and placed on the frame. To rest in a reclining position, the seat is raised to the first click.

The main difference and feature of the design - raster armrests. They are regulated separately, occupy different positions after pressing, visually change the design of the sofa. The armrest, located at a slight angle, replaces the pillow. The design and mechanisms withstand daily operation, suitable for apartments with a limited area. For folding you need to set the sofa at a distance of 15 cm from the wall.

Pantograph (tick-tac)

Due to the improved pendulum transformation "pantograph" is considered a good option for sleep. Conversion to bed occurs in two stages. The lower segment is lifted with a hand strap and pushed forward, at which time the backrest synchronously lowers to the empty seat. The folding block in a horizontal position holds the springs, eliminating loosening, creaking, distortions. The transformation takes place in an arc on the springs, the structural elements do not touch the floor covering. Durable frame and fittings withstand a weight of about 220-240 kg.

The advantages of the pantograph system:

• quick unfolding;
• the floor does not spoil the rollers;
• wide seat;
• sofas have a concise design, but always come complete with original pillows.

The disadvantage is the high price.

French cot (mixotul)

The design consists of a frame and a soft block, under which there is a transformation system and a mattress folded three times. The mechanism is lifted by the handle, moves apart in two steps. The legs of the profile pipe independently fall to the floor. Formed monolithic sleeper with a base in the form of a grid, lat or awning.

The French folding bed has strengths and shortcomings:

The spine is evenly supported by a model with a base of curved lamellae and an awning.

Spartacus

The transformation system was developed by a Russian-Italian furniture company, which is identical in principle to a French folding bed. Folded three times divanny mechanism lifted loop, which is located on the frame of the sliding part. To fold the design, the extreme part rises, the legs are folded. The assembled system with the mattress is placed in the box. The length of the sleeping bed in "Spartacus" is increased to 190 cm. The frame of steel pipes and thick rods can withstand the weight of 220-240 kg. The coarse reinforced mesh does not flex under the weight of the body. The sofa is comfortable, fairly reliable, easily transformed. But because of the thin mattress during sleep, transverse details are felt on the frame sections. The quality of the bed is not enough for daily sleep.

Conrad or Telescope

The folding system is located under the seat, consists of three parts. When unfolding the lower unit rolls forward and pulls the next segment. The upper part of the soft back fits into a niche. All elements easily and silently move, maintain frequent transformations. A sofa with a deep seat looks a bit cumbersome, a place to sleep is at a height of 45 cm. For comfort, "Conrad" with a block of independent springs is not inferior to a bed, the structure has no weak links. Sofas are available in angular and direct form, suitable for the hall, bedroom.

Advantages of structures with a telescopic mechanism:

• high folding speed;
• most models have a storage system;
• stable and durable frame.

Sedaflex - American folding bed

The design resembles a double folding bed with a reinforced frame. The mattress is fixed on the suspension, which consists of slats, mesh, elastic belts. This combination provides a comfortable surface for sleeping and lying. On the retractable base is regulated the height of the head. During unfolding, the section emerges from the niche, moves forward, and is mounted on steel legs. The kit includes a mattress made of polyurethane foam with a height of 10-14 cm or spring blocks. The process of assembly and disassembly occurs in the air, the legs of the sliding part do not scratch the floor. The transformation mechanism wears out slowly, sometimes rivets and lamellas break. Spare parts can be purchased at the store and independently repair the base. A full bed is created quickly and quietly, suitable for people with a large weight, can be applied daily.

Elf

The sofa meets the requirements for sleeping place.

• The frame of profiled tubes and lamellas provide a smooth surface.
• Large items are placed in a deep and tall linen box.
• The berth is extended by armrests, which are installed in different positions.
• Highly elastic flooring does not sag in intensive use.
• The wheels with polyurethane coating do not leave scuffs and scratches on the floor.

Armrests in folded and unfolded form withstand the weight of 40 kg. But it is not recommended to sit on them, jump.

Puma

The transformation mechanism is designed for daily use. In combination with a solid frame, spring block guarantees 10 years of service without jamming when extending the elements. In the folded state, the segments are under each other. For folding, the front mat is raised, carried forward, mounted on a retractable support. The second half fits into a vacant niche. It creates a wide bed with a height of 45 cm without a gap between the parts. The synchronizing telescopic device promotes consistency and smooth movement, tight coupling of the halves on 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 conditions for relieving muscular tension, regulates the back at different angles, advances the footrest. Modules move independently of each other, each person can adjust the seat to fit their needs. The back goes down after pressing, returns to the initial position with the help of a lever. Luxury sofas are equipped with electric drive, all functions are switched on with the remote control. The furniture is not designed to sleep, but after reclining the back on it you can sleep. Sofa-recliner is placed in the recreation area or reception. The price of products is high, even with standard options.

Transformer

Transforming models created to save space. In IKEA, you can find a wardrobe-bed, complemented by shelves and a table, or bunk transforming sofas. Variable furniture is difficult to put together, but in small rooms it is not possible to place all the necessary items in another way. The transforming sofa 3 in 1 will be suitable for the hall, guest or a nursery. Lifting systems and Blum fittings work smoothly, simplify access to the upper tier, rollback, quick assembly. In disassembled form, two beds are formed at the bottom and one at the top. Individual blocks of transforming sofas form a sleeping bed of the right 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 transferred to the position of the bed without noise by moving up and towards yourself. After unfolding, parts are installed on steel supports. When folded, the two sections hide under the seat. The transformation mechanism with frequent use does not leave rolled tracks on the floor covering. Convenience provides a flexible metal frame with a lattice base and a thick layer of medium hardness filler. Furniture foam rubber is resistant to bending, does not stratify, withstands daily loads. The berth is calculated on height of 190 cm and the weight of 200 kg.

Advantages of sliding system Cheburashka:

• reliability;
• small sizes when folded;
• an even berth which does not sag with time;
• low price

Cons - no laundry container.

Automatic gear

All actions to create a place to sleep performs the drive after pressing the button on the remote. The block, located under the seat, straightens and rolls forward in a few seconds, unfolds without distortions. Such a convenient option is too high a price, but it is justified by a long service life. Transformation mechanisms for electric sofas are made of high-strength materials, staffed with a base and a mattress with orthopedic properties. The design provides a lever in case of power outages. After unlocking, the furniture unfolds manually.In some models with automatics, the position of relax, massage devices, footrests, adjustable head restraints are provided.

Sofa with unfolding to the floor

The place to sleep is hidden in the cabinet and moves on rollers mounted on the sofa frame. To convert to bed you need to pull the strap on the front of the seat. The blocks are removed outside without the application of physical force, they are laid directly on the floor without supports. In the roll out half can be a box for laundry with a durable cover that serves as a berth. A double folded mattress is thrown on it from the seat.

The simplest, most convenient and cheap transformation has disadvantages:

• low bedtime, only 25-30 cm from the floor;
• the mattress is thin, on the unfolded part it is softer to sleep than on the frame, the halves disperse on the floor.

Swivel mechanism

The berth is formed by displacing 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 complicated manipulations, thanks to the smoothly sliding roller. So that the resulting bed does not disperse to the sides, a hook is provided that holds two blocks nearby.

Benefits:

• spacious place with a smooth surface;
• in the design there are no small elements subject to breakage;
• the rotary transformation mechanism is combined with an orthopedic base;
• one or two laundry boxes.

Disadvantages: high cost.

Lit

Single compact sofa with a wide seat lengthened by armrests. Lateral parts rise against the stop and unbend outside. The armrests can take a completely horizontal position, be at a certain angle. The model is suitable for a nursery, grows with the child. With two unfolded armrests, the seat is extended to 200 cm.

Advantages of the Lit transformation mechanism:

• compactness;
• comfortable bed medium hardness;
• the possibility of fixing armrests in 3 positions;
• capacious box for a bed or toys.

How to choose a sofa according to the type of transformation

Before buying you need to take into account the size of the room, the number of family members, as far as the layout mechanism is within their powers. A small area in a disassembled form is occupied by a book, eurobook. The folding systems are reliable, time-tested, require little effort, but are intuitive, rarely break. The improved click-klyak mechanism is easier to transform, it is brought into the "half-sitting" mode, but it is more vulnerable. Furniture makers, the pantograph and the accordion, have earned good marks from furniture makers. The clamshell often deforms the details of the frame, they are best used as a guest option. For a child, a teenager, one person, designs with folding armrests will do. When assembled, the couch length is 1.6 m, after transformation, 20 cm is added to each side section. People who have back problems should take a closer look at the relays.

Which sofa to choose for sleeping?

The sofa, which will be used as a bed, should be transformed without noticeable efforts, create a sufficiently rigid berth with a minimum width of 140 cm. Folding and retractable structures are most adapted to daily transformations. Reliable straight "books" a little under-fit in width. Spacious bed form corner models. Sofas produced with a different base under the mattress. It is recommended to choose the block "snake" or elastic arc-shaped armor, providing a springy effect. The strength and durability of the furniture depends on the frame. They withstand intense loads made of wood, multilayer plywood, metal.

Sofa: with or without springs

Filler affects good sleep, well-being, health. On too hard or soft falling place, the spinal column is bent. Spring blocks provide good support to all parts of the body. They evenly take the load from the body, retain their properties for a long time, and are recommended for people with a lot of weight.

High-quality porous materials, polyester fibers, latex dampen vibration, resist loads, quickly restore shape, support the body well. Soft foam rubber is quickly deformed, soft foam rubber is lying, it loses the shape of a synthetic winterizer.

Which is better?

It is impossible to answer unequivocally which inner content is better. Each material has its own characteristics.

Comparison of fillers:

Owner reviews

As the reviews show, if you choose the transformation mechanism correctly, the sofa will not disappoint, it will last for a long time. The most reliable consider roll-out and folding systems. They speak well of the accordion system, which forms a sleeping place comparable to an orthopedic bed. Among the clamshells distinguished sedafleks, which attracts a thick mattress and non-sagging base. No less popular are modular designs for living rooms. With built-in side tables, shelves. Owners of small apartments recommend transformers 3 in 1, replacing the sofa, table and bed.

Conclusion

Transforming sofas do not need a colorful description, because with some drawbacks they are the only possible option for placing 8 square meters. Longitudinal models without transverse seams are usually bought for sleeping. Corner sofas are suitable for large families, zoning space, reception. Built-in storage system will eliminate the problems of finding a place for bedding, seasonal items. The choice of sofas with large transformation mechanisms, ask questions before you buy, lay out the structure, evaluate the height and rigidity of the mattress or look at the characteristics specified in the documents.
