How are sofas laid out? Sofa layout mechanisms: which ones are the most reliable. Which sofas are by name.

The sofa is one of the most comfortable pieces of furniture. It is unlikely that something else can be compared with it in terms of comfort. It is much more functional than a bed. Due to the fact that there is a mechanism for unfolding the sofa, you can arrange an extra bed for an adult or a child.

Ideal for lovers of modern practical style.

Most apartments allow you to place such a piece of furniture without compromising free space. During the day, the sofa usually plays the role of a comfortable seat, like an armchair, but you can also “reclining” on it, and even sleep, if suddenly a dream overcame you at an inopportune time.

It is roomy with its fairly compact size, so it is appropriate in a room of any size.

Familiar to all furniture today has many modifications. It is chosen by the owners of commercial establishments, and the owners of apartments, and the inhabitants of country cottages.

Sofas are divided into a number of types, depending on the purpose:

• kitchen;
• for children;
• for the living room;
• for the office;
• for the hallway.

Quite compact, it will at the same time provide you with a full-fledged place to relax.

Mechanisms for transforming sofas for living rooms and children's rooms provide an increase in comfortable space. If necessary, it turns into a bed. The child can play on the floor, and then lie down to rest or read.

Unlike most corner models, it has a comfortable backrest for sitting and two sides with wooden armrests, which provide comfort for the whole family while watching TV or just relaxing.

Office, kitchen and hallway models usually do not have additional folding parts - there is no sofa transformation mechanism in them, because visiting these places does not involve spending the night.

Types of sofas by design features

A variety of designs allows you to choose stylish and practical sofas to your liking.

There are several types of structures that differ in shape:

• angular;
• straight classic;
• island.

A versatile sofa, because by transforming with a simple roll-out mechanism it turns into a comfortable double bed.

Corner-shaped furniture is convenient for small rooms where there is a free junction of two walls. Such sofas take up a minimum of space, may have additional modules (remove if necessary).

The spring block and the filling of polyurethane foam, an environmentally friendly material, ensures the anatomical position of the body during sleep, so that rest is complete and healthy.

The straight model is usually located against one of the wide walls. Not all models have sofa folding mechanisms with a similar design. To provide an extra bed, you need to choose furniture with a layout system.

The convenience of the sofa is added by the presence of a linen niche in which you can store bedding.

Types of island-type sofas can be different. The modules are laid out in the desired position, providing a wide area for lying down.

Long service life even with intensive use is possible thanks to the wooden frame.

Types of sofas by type of transformation

The type of sofa unfolding significantly affects the degree of comfort. If the sleeping place is planned to be large, then it is necessary to choose a design based on the area and layout of the room.

The original design of the sofa and its carefully thought-out forms will be the highlight of the room.

Sofa transformation mechanisms dictate the type of layout:

• "Book";
• "Tango";
• "Lit";
• "Dolphin";
• "Puma";
• "Pantograph";
• "Clamshell", etc.

This is one of the most popular mechanisms today.

When choosing, one must proceed from the extent to which one or another layout is within the power of family members, since tight and complex mechanisms can jam and require more physical costs for them.

At the heart of his bed is a high-quality spring block, which allows the child's spine to stay in an anatomically correct position, thus not bending

The mechanism of transformation of the sofa "Book"

One of the most popular types of sofas. Bringing the structure to a horizontal position takes a minimum of time. You need to pull the seat towards you, and lifting it until the lever is activated, you can easily lay out the sofa for sleeping.

While the child is small, the sofa can be used without unfolding.

The mechanism for transforming the sofa "Book" is reliable and simple, because it provides a sleeping place very quickly. You can use the furniture for a long time without loss of performance.

The sofa book combines the advantages of a classic sofa and modern functional solutions.

Types of sofas that transform for a comfortable position and sleep:

• straight;
• angular ("Eurobook" or "Tango").

Has practical armrests, a high and convenient back.

The latter have a shorter head part, a long (narrow) one unfolds flush with the head part - a solid area is obtained for a comfortable stay. The mechanism for transforming the sofa "tango" is similar to the mechanism for laying out a straight "book". It is necessary to pull the seat towards you and up until it clicks.

Filling - high-quality safe polyurethane foam with a spring block.

Click-clack sofa: increased comfort

Type of sofa, according to the layout principle, reminiscent of a "book". To bring the bed to a horizontal position, it is necessary to pull the seat up until a characteristic sound is heard.

The mechanism for transforming click-clack sofas is as simple as that of the previous type.

To unfold the sofa in a horizontal position for subsequent sleep, you do not need to make great efforts, unless the structure is severely deformed from long-term use.

The sofa will perfectly take its place in the living room or bedroom.

Of the mechanisms for transforming sofas, this one is one of the easiest. Often, such models can be seen in a teenager's room or bedroom.

The sofa will provide an extra bed if relatives or friends come to visit.

Sofas "Lit" and roll-out type

Two types of designs - "lit" and roll-out are also very popular due to the quick unfolding for sleep. The sofa "lit" is transformed easily. Armrests can be placed both for a children's bed and in order to arrange a comfortable sleeping place for an adult. To bring the sofa into the desired position, you need to pull the seat towards you, fixing it after the lever is activated.

Roll-out furniture does not require effort, the load goes to the rollers. When moving towards you, the parts are transformed into a horizontal position, it remains only to align them and place pillows for convenience. The sofa provides an extra bed for an adult or two for children.

Filling - high-quality safe polyurethane foam with a spring block.

Mechanisms "Puma" and "Dolphin"

The Puma layout type is also a leader among simple sofa mechanism control systems. In a horizontal position, the structure is brought in one or two movements. It is enough to pull it towards you until it stops - an additional part will appear, previously hidden inside. The third part is filled with a back.

The sofa with the Dolphin mechanism is also distinguished by a similar compactness. The difference is that the additional block extends from the bottom of the furniture, which then becomes flush with the surface. The bed is large, and when folded, the piece of furniture is very ergonomic.

With the help of the mechanism, you can easily expand the sofa, getting a full-fledged double bed, while for your convenience there is a spacious linen niche.

Choosing a sofa depending on the size of the room

When purchasing folding furniture, you need to focus on the area of ​​\u200b\u200bthe room where it is supposed to be placed.

• For children's rooms, sofas of a single layout such as "book", "lit" or roll-out are suitable. The size of the sofa also matters. For children, choose the environment in specialized departments of stores, as there products undergo strict environmental certification. Furniture will be safe from the point of view of mechanics.
• For living rooms and bedrooms of large sizes and with a square layout, sofas with a double layout are convenient. They provide, if necessary, a replacement bed, and you can stay on them with great convenience.
• Pull-out sofas are a great alternative to beds in a country house where there are several small guest rooms. During the day, you can sit on them, reading a book or watching TV, and at night you can sleep comfortably.

Elegance is added by spectacular wooden legs.

Quality of mechanical parts

When choosing a folding sofa, give preference to reputable manufacturers, and repeatedly check the mobility of the mechanisms in the store, since typical models may contain defective parts. If the mechanics are tight, there is a feeling of looseness of the guides - the question arises of little quality control on the part of the manufacturer.

The best option would be to make a sofa to order. With this approach, you can not only purchase a quality item according to individually declared sizes, but also control the progress of work. In most cases, you will also avoid overpaying. The furniture will pass careful control before you receive it in finished form.

The sofa will perfectly take its place in the living room or bedroom.

sofa operation

Despite the guarantee issued by the sofa manufacturer, under certain influences, it can become unusable much earlier. It is required to handle a folding sofa carefully - try not to pull the folding parts and not take them to the sides, loosening the transformation mechanism.

Since the hinges and levers are predominantly metal, they do not tolerate excess moisture. Therefore, when cleaning the sofa, try to use a wrung out sponge or a slightly damp brush. Contact with caustic detergents on the mechanisms can cause metal corrosion.

The base of the sofa frame is made of natural wood, the body material is high-strength fiberboard.

What elements make up the design of sofas

How sofas differ in design and purpose

What are the designs of sofas for unfolding

Usually a sofa is purchased for more than one year, therefore, it is necessary to approach its choice responsibly. New upholstered furniture should fully meet its purpose, be comfortable for the whole family and be in harmony with the interior. That is why, choosing this kind of furniture, you should pay close attention to the design of sofas.

What structural elements are sofas made of

As a rule, when purchasing a sofa, we first of all pay attention to its appearance, namely, upholstery fabric, color, shape, etc. However, when choosing a specific model, it is important to study the design of this piece of furniture, because its quality characteristics depends on how long the sofa will serve you.

What is the design of the sofa?

Armrest. Usually it is made of wood, chipboard, MDF, metal. The armrest can be upholstered in fabric or leather. When purchasing a sofa, give preference to models whose armrests are made of wear-resistant materials (wood, metal, MDF, leather).

Upholstery. It can be a special fabric, leather.

A layer of synthetic winterizer or batting.

Filler- foam rubber for furniture.

Polyurethane foam pad(PPU), which is necessary for increased wear resistance and uniform weight distribution. Such inserts give the sofa orthopedic properties.

spring block- This is the main shock-absorbing part of the sofa design.

Burlap or felt. These materials smooth out the friction of metal on plywood, thereby preventing the appearance of unpleasant sounds.

fibreboard(Fibreboard) - is the base of the sofa mattress.

sofa frame. It can be made of wood, metal or chipboard (chipboard). The frame is a structure that bears the main operational load and determines the shape of the sofa. Therefore, when choosing, pay special attention to the quality characteristics of the tree from which the frame is made. The presence of knots is undesirable, since in these places the wood can burst.

Interlining.

Roller rail. It can be located at the bottom of the box and be made of both wood and metal.

Box or niche designed for bedding.

Extendable part, which is used during the transformation.

Types of sofas by design, purpose, size and number of seats

Direct models are classics. Their main advantage is that the size of the sofa can be selected depending on the area of ​​​​the room. They come with or without armrests, transforming or stationary.

corner sofas are well known and in demand among buyers. They are comfortable and functional, can be installed in various rooms, for example, in the kitchen.

When choosing this model, the question may arise about what to do if you need to rearrange the sofa to the other side of the room, how to properly disassemble the corner sofa. The design of many models for such a case suggests the possibility of reinstalling its corner part. The sides of such a sofa can be either different or the same length.

Modular pieces of furniture can be collapsible and, like a designer, be transformed at the request of their owners. This type of sofa has such a design, thanks to which it is easily modified in accordance with the interior of the room. This advantage will save you from having to buy new furniture in case of a move. The modular sofa is perfect for rest rooms with a home theater.

Island types of sofas are initially rounded, they are most often located in the center of large rooms. Furniture of this type is able to create a unique interior. Their special form is often harmoniously complemented by other furnishings.

All types of sofas according to their purpose can be divided into:

• for the living room;

  for kitchen;

  for the hallway;

  for children.

At the same time, the types of sofa designs are different, in this regard, it is necessary to choose a specific model that will suit you exclusively. Usually the upholstery of the sofa determines its purpose.

For example, upholstered furniture, upholstered in leather or similar cheap materials, is usually intended to be placed in offices or in the kitchen.

Sofas for children's rooms in most cases are covered with colorful, rich, but quite practical fabrics, from which various stains can be easily removed.

There are compact models of sofas designed for two or three people, and large ones for five or more seats. It should be noted that there is no single standard for the size of such upholstered furniture. For example, one factory produces a two-seater sofa, the length of which is 1.6 m, while the other one will have the same length of 1.9 m.

Sofa designs according to the folding mechanism

"Book"

Sofas of this design are transformed into two positions: sitting and sleeping. In order to expand the sofa into a bed, you only need to fold its back back. When unfolding, it does not have to be moved away from the wall, because when installed, a small gap is specially left between the wall and the back.

The design of the “book” sofa consists of two frames, which are made of metal or wood, with fixed spring blocks or other soft filler. The laundry compartment is usually located at the bottom.

Advantages:

long service life;

functionality;

ease of operation;

regular use without breakage and wear.

Disadvantages:

there are only two positions - lying and sitting;

cannot be installed against a wall.

"Tango"

This model of sofas is transformed by the “click-clack” method. And it is called "tango" because the manufacturers simply want to surprise the consumer with an unusual name. Although this design is very similar to the classic "book". However, there is one difference - when laying out such a sofa, there are not only “sitting-lying” positions, but also intermediate ones. The back can be set at the level that is most convenient for you, in addition, it has a box for bedding.

Advantages:

backrest in different positions;

compact size;

after unfolding, a smooth surface is obtained.

The disadvantage is the inability to install the sofa close to the wall.

"Eurobook"

The design of the Eurobook sofa makes it easy to recognize it among the classic models: it unfolds with the help of roll-out rollers that push the seat forward. In the resulting niche fits the back of the sofa.

Advantages:

ease of transformation of the sofa into a bed;

large niche for storing various items / things;

capacity;

the strength of the sofa design.

The disadvantage is that due to the sufficiently large seats on the sofa, people of short stature and children will feel uncomfortable, because they will not be able to lean on the back.

"Dolphin"

This is the most famous mechanism for folding corner sofas. The design of the sofa "dolphin" is quite simple. To transform it, you need to pull the loops that are attached to the section under the seat. You need to pull up and down at the same time. The section moves out and stands next to the seat, creating a spacious sleeping area. The linen storage compartment is located in the stationary part of the seat.

Advantages:

comfortable place to sleep;

simple and easy to unfold.

The disadvantage is a short service life with regular use of the mechanism.

"Pantograph"

This design of sofas is also called "puma" or "tic-tac". She appeared as a kind of "Eurobook", but without rollers for rolling out the seat. Inside there is a large storage box.

In order to expand such a sofa, you do not need to make much effort - just pull the seat up, holding its edge in the middle. Thus, the mechanism will begin to operate, which pushes the seat forward and upward and opens the legs of the support. In the opened niche you need to lay the back-pillow.

Advantages:

comfortable place to sleep;

simple and easy folding mechanism;

rollers without damaging the flooring.

Disadvantages:

high cost of the working mechanism;

pretty wide seat.

"French cot"

The sleeping area of ​​this sofa consists of three sections. In order to expand them, you only need to pull the edge of the seat. For regular use as a bed, this type of furniture is not suitable, because these types of structures wear out quickly enough.

The advantage is the compactness of the sofa when folded.

Disadvantages:

uneven sleeping surface

lack of a box for storing linen;

short service life.

Advantages:

durable and reliable design;

comfortable bed;

small assembled dimensions.

Disadvantages:

rollers for rolling out a berth can scratch the floor covering;

bed is low.

"Accordion"

This type of sofa got its name for some resemblance to the musical instrument of the same name. The sleeping place of the “accordion” sofa with this design characteristically spreads forward, leaning on retractable legs. In the initial position, the sofa takes up very little space; in the area of ​​\u200b\u200bthe rear back there is a box for storing bedding.

Advantages:

strong and reliable mechanism;

long service life;

does not require any effort when unfolding.

Disadvantages:

lack of a built-in niche for linen;

The withdrawable mechanism may scratch the flooring.

"Spartacus"

To transform the sofa to sleep, you just need to pull the seat, which unfolds in three steps and stands on mobile legs. Such a mechanism was developed jointly by Russian and Italian manufacturers. This furniture is ideal for sleeping, it is the best sofa design that provides the most spacious sleeping place. In fact, this is a French clamshell, but more reliable, reinforced with a welded metal grill.

Advantages:

reliability and long service life of the unfolding device;

Advantages:

durable mechanism;

the possibility of daily use;

compact dimensions;

availability of storage space;

favorable conditions for sleep.

The disadvantage is that it is too massive due to the volumetric folding mechanism.

"Sedaflex" ("American clamshell")

Such a sofa transforms like a French folding bed, but, unlike it, it is equipped not with a three-fold, but with a two-fold design and a thicker mattress.

Advantages:

reliable mechanism;

compact size;

quality ergonomic mattress.

Disadvantage: no niche for storing linen.

Advantages:

compact size;

comfortable place to sleep;

thanks to the lamellas, an orthopedic effect is achieved;

armrest adjustment.

the place to sleep is in the same place as the seating.

Recliner

The name of this type of construction comes from the English "recline" - sit back. It unfolds through complex built-in mechanisms. Using them, you can adjust the backrest or extend the footrest. In addition, some models have special pillows with vibration massage. The most expensive samples have a remote-controlled electric motor.

Advantages:

ease of management;

the ability to customize ergonomic functions;

comfort in different positions.

Disadvantages:

high price;

no place to sleep.

Sofa with unfolding on the floor

The place to sleep consists of two compartments, which in the assembled position are located inside the sofa body. In order to unfold it, you need to pull the inner edge of the seat up, then forward and towards you. The place to sleep does not imply any supports and is located directly on the floor.

Advantages:

compactness when folded;

the cheapest type of folding sofas.

Disadvantages:

uncomfortable place to sleep;

lack of a niche for storing things.

Having studied the designs of sofas, the photos of which are presented in this article, you can determine which of the folding mechanisms has become the best in its class:

"Eurobook" - has the most durable mechanism;

"tango" - the most comfortable for sitting;

"Dolphin" - the most spacious;

"Pantograph", "accordion" and roll-out - it is most convenient to sleep on them;

"tango", "eurobook" and roll-out - equipped with special niches for storing things;

roll-out and "elf" - are considered the most compact;

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"

When 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 flat 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 with 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, the lamellas give a good orthopedic effect, the armrests are adjustable, 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.

For a rational choice of a sofa, you should first find out what types of sofas exist. What are their differences, advantages and disadvantages.

There is no strict classification of types of sofas. In this review, I will be guided by the fact that sofas can be classified depending on their design and functional (purpose of the sofa) features. So let's go.

What sofas are depending on the design

In this section, I have selected the most significant design differences between types of sofas. These can be attributed

• the ability of the sofa to change shape and size without unfolding - in this part, I divided the sofas into stationary and modular
• the ability of the sofa to transform - unfold
• types of sofas depending on the type of filler
• types of sofas depending on the fabric for upholstery sofa (I think this indicator is the least significant)

Now about each design difference of sofas in detail.

Stationary, modular and island types of sofas

On this basis, sofas can be divided into three groups - stationary, modular and island. Let's figure out which ones are better.

Stationary sofas

Stationary sofas are sofas that have a fixed size. They do not allow you to change the shape and size of the product. Usually, a stationary sofa is placed along the wall. Often, the back wall of the sofa has a more economical finish (for example, felt), which differs from the main upholstery.

In turn, stationary sofas can be divided into:

Direct sofas - usually used in small spaces. There are folding and non-folding

Corner sofas - there are also folding and not folding .Corner sofas require more space.

• To the virtues stationary sofas can be attributed to the fact that when unfolding the sofa turns into a comfortable bed. You can use this sofa for both sitting and sleeping. The prices for such sofas are also quite lifting.
• disadvantage stationary sofas is a certain massiveness and not the possibility of changing the shape and size.

Modular sofas

A modular sofa consists of parts - modules that can be combined in different orders and create a single product. You can also use sofa modules as independent furniture elements.

Of course, such models are mobile and suitable for creative individuals. You can change the configuration and general appearance of the sofa. Due to the compact size of the modules, modular sofas are easy to move and transport.

• Advantages of modular sofas mobility in every sense, transformation and change in the general appearance of the product
• To disadvantages can be attributed to the fact that such sofas often do not have a bed and have a higher price than stationary sofas, the range of modular sofas on sale is much smaller than the range of stationary sofas.

This type of sofas is used to organize places to relax. At the same time, the sofa is not placed along the walls, but far from them. The sofa forms a semblance of an island. Island sofas have an attractive look from all sides. In shape, they can be round, semi-circular, oval and rectangular. Using an island sofa requires that there is enough free space in the room. The approach to the "island" should be free from all sides. Island sofas come in a variety of sizes. From one or two local to 5-6 local versions.

• Advantages of island sofas mobility, stylish and unique appearance
• disadvantages sofas do not have a bed, require large spaces, have a high price

Conclusion: if you need a sofa to organize a sleeping place, then you need a stationary type of sofa. If you want to organize seating and daytime activities, take a look at the modular versions. An island sofa is good if there is a lot of space in the room.

The design features of the sofas allow you to create sofas of various shapes. A detailed description of the possible forms of the sofa in this article.

Types of sofas depending on the ability to transform

Sofas are folding and not folding.

This type of sofa contains a transformation mechanism in the design, which is located inside the sofa body. There are more than a dozen sofa folding mechanisms. You can read more about all the mechanisms of transformation

When the sofa is folded, the mechanism is not visible. The mechanism allows you to convert the dimensions of the sofa. Usually folding sofas are needed to organize a place to sleep. Folding sofas can be both angular and straight.

• Advantages of folding sofas the possibility of transformation increases the functionality of the sofa - a sofa during the day, a bed at night. Pull-out sofas can contain additional drawers for linen hidden inside the sofa
• The lack of pull-out sofas associated with the reliability of the mechanism itself and the frame of the sofa. If the transformation of the sofa is frequent, then its wear increases. You need to carefully choose a reliable mechanism and a high-quality sofa frame when buying it.

Sofas are not folding

From the name it follows that this type of sofa cannot be converted into anything. Typically, these models are used to organize seating. Non-folding sofas can be used in pairs and or together with armchairs, creating a seating area, for example, around a coffee table in the living room. Normally, such a sofa will work in your kitchen or dining room. If the area allows, then you can use it in the hallway

• Advantages of non-folding sofas: compact size, low price
• Disadvantages of non-folding sofas: weak, limited functionality

Conclusion: if you need a multifunctional assistant, as in advertising all in one bottle, then you need a folding sofa. If the functions are more modest - just sit, then you can save a lot by buying a non-folding sofa.

Types of sofas depending on the type of filler

On this basis, two main groups can be distinguished.

Sofas filled with spring blocks

In such sofas, the filler is a structure made on the basis of metal springs. The springs can be connected in blocks or independent. Also, the spring block can have a common metal frame. This type of sofa is good for sleeping. Spring blocks have a long service life and are comfortable to use.

Sofas with filler without springs

As a filler without spring sofas can be:

• foam rubber
• PPU - polyurethane foam
• latex
• polystyrene balls

Conclusion: the choice of filler type depends on the functional purpose of the sofa. For sleep, it is better to use sofas based on spring blocks or with latex filler. If you want to save a lot, foam rubber will help you, but then the sofa will have to be changed very quickly. PPU occupies a middle position. It will do a good job of solving problems - a sofa for sleeping and for sitting.

There are a lot of upholstery. Read about the intricacies of choosing upholstery for sofas.

Fundamentally, upholstery can be divided into

• natural (cotton, leather, tapestry, jacquard, silk)
• semi-synthetic - consist of a combination of natural and synthetic fibers (flock, chenille)
• synthetic - consist entirely of artificial components (artificial leather)

But, I believe that among other design features of sofas, upholstery fabric plays the least importance. Because it's the easiest to replace.

General conclusion on upholstery: look at them last - the design of the sofa is more important than its appearance. The choice of upholstery type depends on the purpose of the sofa.

Look at this sofa and think about where it can be used. After a short evaluation, it turns out that there are not so many possibilities for using it.

You can find a classification by purpose, which is based on the types of premises in which the sofa will be used.

What will we get as a result

• Living room sofa
• Bedroom sofa
• Sofa for kitchen, dining room
• Sofa for children
• Sofa in the hallway
• Sofa in the office or library
• Sofa for loggia and balcony

It seems to me that such a division is not very correct. Yes, it has the right to life, but the same sofa can be put in any of the rooms. The question is different. What would you do on this sofa - sleep, eat or just sit. Do you understand what I mean? You can eat in the living room and sleep in the kitchen.

Therefore, I would single out three key groups of sofas by purpose

• Seating sofa
• Sleeping sofa
• Sofa for sitting and sleeping

Conclusion on the purpose of the sofa: look at the functions that the sofa will solve in your particular case and choose based on this understanding. Do not rush to the marketing tricks of sellers - like This sofa for the living room - buy it and you will be happy. And you want to eat and sleep on it, and in this example there will be happiness, but the seller who "sold" you an unnecessary sofa.

Video - types of sofas, what to look for when choosing

Finally, I offer a short video clip. Everything that I have already told above once again for consolidation. Only now it is already "video language".

That's probably all. I hope my findings help you.

The sofa is the most used element of the interior. It is often used for several purposes at once - for sitting, relaxing or sleeping. Therefore, when choosing furniture, it is necessary to take into account not only the appearance, but also the varieties of sofas: classification, technical characteristics. This will help you choose a visually beautiful model that will complement the interior, but at the same time allow you to rationally use the space of the room.

What are there?

There is no strict classification of sofas, but there are generally accepted standards and terms. When choosing a sofa, as a rule, take into account its design indicators, functional features and spaciousness. Characteristics can be selected in a separate list and rely on when choosing your individual model, which will be especially important if the furniture is made to order.

By shape

It is recommended to choose a sofa of such a shape or design that it does not take up extra space in the room. This element of furniture should be located so as to fill the unused area of ​​​​the room, and the passages or, for example, the play area in the children's room, should be free. By design, sofas are conditionally divided into four types.

• Corner. Such models successfully occupy unused corner niches, straight backs can be leaned against the walls. The corner shape is great for small, one-room apartments, small kitchens. In rooms with a large area, the corner design allows you to zone the space.

• Direct or stationary- the most popular form of furniture due to the many placement options. Straight sofas are conveniently installed along the walls, in the center and corners of the room, small compact models can be easily moved around the room. Most straight sofas are folding or pull-out. Installed in the center of the room near the wall, if necessary, they can serve as a full-fledged double bed.

• Modular sofas- the most mobile and multifunctional type of furniture, their design consists of several parts that can be used both together and separately. If necessary, the parts are combined in a different order, for example, a large corner sofa is disassembled into two straight lines or small separate modules are used as ottomans.

• Island- these models are less popular in comparison with previous forms, since they mainly involve installation in large rooms. Made in the form of islands, they are installed in the same way - in the middle of the room, or in the corner in case of zoning the area. Island models occupy a lot of usable space, but they look presentable and help to implement bold design solutions.

When choosing the shape of furniture, it is important not to forget about its volume, the total area that it will occupy.

The sofa in the hall or in the kitchen should not be too wide; in these rooms it is better to leave more space for movement. In apartments where a folding sofa is planned to be used as a sleeping place, models with a wide seat are suitable, but for rest rooms they often choose designs not only with a wide, but also with a deep seat.

By appointment

The shape and design of the sofa is also selected taking into account the purpose of the furniture, the choice of material for manufacturing, as well as the total cost of the future product, will depend on this indicator. For example, models with inexpensive upholstery are suitable for the kitchen; for sleeping places, it is advisable to order sofas made from natural materials; in work or office premises, leather-covered products are more practical. By appointment, this element of upholstered furniture is classified into five types:

• office, for working rooms;
• for the hall, living rooms;
• for kitchens and dining rooms;
• in the hallway or corridor;
• for children's and playrooms.

If additional beds are periodically needed, it is better to choose a stationary direct type of sofa, it is also suitable for office space.

In places of rest - in the living room, bedroom or dining room - a good solution would be modular version. Island models are convenient for zoning rooms- in the offices, such sofas are equipped with places for informal conversation, in the halls they are installed in front of TVs.

By size

The size of the sofa means not only its actual length and width in centimeters, but also the number of seats (or beds, in the case of a folding version). Compact models, as a rule, are designed for no more than 2-3 people, medium ones - 4-6, and huge modular sofas can accommodate a company of 7 to 10 people.

However, when choosing a finished model, where the dimensions are laid down by the manufacturer, it must be borne in mind that there is no single standard - one manufacturer can offer a double sofa 1.5 meters long, and the other 1.8 m.

An important indicator of the size of upholstered furniture is the height of the back and landing. Sofas for hallways have a low back or are produced without it at all, models with a low back wall and seating are also often installed in halls and bedrooms. In places where it is planned to only sit on the sofa - in the kitchen or in the office space, such options are selected so that the seat height is not lower than a regular chair.

The best choice for a small space would be sofa without side armrests and extra pillows, another trick to reduce the size of furniture without losing functionality is to purchase or order a structure without legs. The possibilities of use will become somewhat limited, it is difficult to clean under such a sofa, but its size will be minimized.

Types of transformation mechanisms

The place of possible installation will depend on the type of mechanism and the method of changing the design. Some models may take up little space themselves, but when transformed, they require much more space. The choice of how to lay out the sofa is also influenced by the purpose of the furniture, the frequency of its use - not all types of mechanisms are designed for frequent use. It is necessary to take into account the estimated weight that will be on the furniture in the unfolded state. So all sofa models are divided into four main types according to the name of the transformation mechanism.

Withdrawable

The assembled design of the roll-out model consists of three separate elements - the rear part in the folded state is a back, and after transformation into a horizontal position it becomes a place for the head. The seats pushed forward and the lower part hidden in the structure are used as the main lying place.

Such models of upholstered furniture are also called - sofas with a telescopic transformation mechanism, because the layout is done from the inside, like a telescope, individual parts are put forward and fixed one after another. Roll-out versions are mainly installed in large rooms, since in the unfolded state the width of the furniture increases by more than three times.

The transformation of the roll-out structure is carried out in several stages.

First, you need to pull the rag handle located in the lower transverse part of the seat, and push the entire seat frame outward. Then you need to level the sleeping surface of the furniture by lowering the back wall down. In some models, additional side pillows are used for these purposes - when assembled, they play the role of a second soft back. The retractable mechanism on such models, as a rule, is based on a roller system, less often - special springs are built into the design, which recline the seats after the lower part is extended.

Sliding

When assembled, sliding models are very elegant and compact, and when unfolded, they resemble a folding bed. After the transformation, the front part is installed on special folding supports, the backrest is lowered, and the assembled bed becomes three separate sections. There are several main types of sliding products.

• "French" folding bed- the classic version of sliding upholstered furniture. When assembled, it takes up little space, but when laid out, the front part moves forward by one and a half to two meters, depending on the specific model. The "French" mechanism is not recommended for frequent use - a sofa can only occasionally serve as a sleeping place, but basically such models are designed more for sitting.

• "American" folding bed. By its design, it is similar to the previous model - the beds are formed from three sections, which are put forward in turn and installed on special supports. The main difference is that the "American" version uses a more reliable and durable mechanism - the furniture is designed for frequent use. However, the cost of such sofas is much higher.

• "Italian" folding bed. Unlike the previous varieties, the “Italian” folding bed is transformed not by lifting the transverse beam of the seats, but by pushing the back wall of the sofa forward. Then the sliding mechanism is also activated, and the surface is installed on the support legs. Compared to the "American" and "French" counterparts, furniture with an "Italian" type of mechanism is equipped with more durable legs.

The most common modifications include accordion mechanism. The principle of its operation is that, moving forward, the berths seem to be stretched with the help of special springs. Metal spring elements, fixed on both sides of the structure, also help to fold the sofa - they tighten the sections inward, setting each in its place. The transformation of these models requires minimal effort - you just need to slightly raise the lower beam of the seats and push it forward.

Just like the clamshell models, the "Accordion" has a very compact size when assembled, it is conveniently installed in small rooms. Another important plus is the presence of a cabinet for linen, located in the back wall of the furniture. Sliding mechanisms "Accordion" are equipped with reliable working elements, have a long service life, withstand considerable weight, are easy to transform, but they also have a drawback - when expanding, the supports slide along the floor and can damage the coating.

lifting

Upholstered furniture with a lifting mechanism consists of two identical parts and involves only two positions - a sitting sofa and a sleeping surface. Horizontal transformation is performed by lifting the seats and folding the backrest back. It is laid on a wooden frame, and the seat beam is lowered into place, in the raised state, the rear wall is fixed with special locking mechanisms.

Before installation, it must be taken into account that between the sofa and the wall, 10-15 cm of empty space will be required for the backrest when it is in the lowered position.

Swivel

Sofas with a swivel mechanism are one of the first to appear on the upholstered furniture market, they are compact and very easy to use, so they always remain relevant. The design involves a minimum of elements, there are no fragile parts, rollers. An important plus is the presence of a box for linen. Of the minuses - there should be a distance of 10-15 cm between the sofa and the wall, which is necessary when unfolding - the seats rise, and the back wall leans back, forming a place for the head.

Thanks to the stoppers, the backrest can be deployed, fixed in the middle position, which is why the models are called swivel.
