folding

Folding models are quite convenient to use. To make a spacious bed out of a compact sofa, you will need to spend a few seconds of free time.

Folding sofas include:

Accordion

When folded, it occupies a minimum of free space, when unfolded, it provides a spacious sleeping place. As a rule, the bedding storage compartment is located in a niche under the sofa. Its advantages include: the durability of the folding mechanism, stability and reliability, ease of transformation. Cons: since with this method the sofa unfolds forward, then there should be enough space in front for its transformation.

Dolphin

The most popular corner sofa that unfolds by pulling the loop under the seat towards you. When unfolded, it pleases consumers with a spacious bed and an additional drawer for linen. Its advantages include: the presence of a comfortable and spacious bed, ease of unfolding, aesthetic appearance.

The Dolphin mechanism exerts a heavy load on the body of the product. Therefore, it is necessary to choose products from high-quality and durable materials.

Book

When unfolding a piece of furniture, its back leans back. To do this, you do not need to move the product away from the wall, as it is immediately installed with a small margin. Book models consist of a metal or wooden frame, spring blocks or any other filler. At the bottom, they are often equipped with linen drawers. Its advantages include: strength and reliability, wear resistance ease of use.

Eurobook

It belongs to the classic models, in which, when unfolding, the seat is pushed forward, and the back is lowered in its place. Its positive qualities include: ease of unfolding and folding, reliability of the mechanism, a large bed, the presence of a niche for storing things.

Click Clack (Tango)

Refers to an improved model of a sofa-book. The product got its name because of the sounds that are made when the mechanism is unfolded.

The model has three positions: lying, sitting and reclining (relaxation).

Some products are additionally equipped with side parts that transform into armrests and headrests. Even when unfolded, upholstered furniture occupies a minimum of free space and is perfectly placed in small apartments.

Tick-tock (pantograph)

Its transformation system resembles a eurobook, only there are no roll-out rollers. Inside there is a spacious box for bedding. To unfold the Pantograph, it is necessary to pull the seat up, grabbing it by the edge in the middle. The advantages include: ease of use, the presence of a spacious bed, the absence of rollers that spoil the floor covering.

French cot (aka Spartacus)

It consists of three sections, which are laid out by pulling the product over the edge of the seat. The French folding bed model is not intended for regular unfolding, as its mechanism wears out quickly. When assembled, the sofa takes up little space.

Sedaflex (American folding bed)

It unfolds like a French folding bed, but differs not in three, but only in two sections and a thicker mattress. Among the advantages it is worth noting: the strength of the transformation mechanism, compactness, the presence of a comfortable and high-quality mattress.

Italian cot

The advantages of the model include the fact that for its unfolding there is no need to first remove the pillows. This option is one of the most reliable and easy to use.

puma

The design of the piece of furniture is original, simple and easy to use. When unfolding, the front part rises, is carried forward and mounted on supports. The rest of the product fits into the vacated space. The special synchronization of the system and the high reliability of the transformation mechanism make it possible to use the piece of furniture on a daily basis. It is worth adding to the advantages: compactness, ergonomics and original design.

Saber

Quite an easy-to-use type of construction that can be fully or partially unfolded. Features include the presence of a linen box and a high place to sleep. Depending on the chosen modification, the bed consists of two or three sections. To unfold the product, you need to roll out the seat, fold the backrest forward and lower the additional shelf.

With withdrawable mechanism

In roll-out models, one or two sections of the sofa are hidden in its body. To unfold the product, you need to pull the bottom part towards you.

Common models include:

• Venice. The principle of operation of this withdrawable mechanism (see photo above) resembles the Dolphin model. To prepare a sleeping place, it is necessary to push the section, which is located under the seat of the sofa, all the way towards you. After that, the pillow that hides inside will lean back into the vacant niche. The piece of furniture is quite simple and easy to use. Manufacturers offer straight or angular models that do not take up much free space;
• Telescope. To unfold it, you need to pull its lower part towards you. In this case, the sections will roll out one after another and stand on their legs. The advantages include: a sleeping height that is comfortable for sleeping, the reliability of the mechanism, the possibility of regular use, compact volumes, the presence of a box for linen. But keep in mind, due to the unique unfolding system, the product is quite heavy in weight.

with swivel mechanism

A feature of models with swivel mechanisms can be called the ease of unfolding - folding. In them, the entire load goes to the frame, they do not need to lift the blocks and roll out the sections to the stop. Depending on the chosen model, both one part of the sofa and each individual block can turn when unfolding.
A popular model of a sofa with a swivel mechanism is:

• Scissors. Its transformation mechanism is to rotate one section to another. At the same time, the blocks are securely fixed to each other with a metal fastener from below. When transforming sections, a bed with bedside tables is obtained.

Without folding mechanism

These pieces of furniture do not contain any transformation mechanisms. That is, they do not fold out and are intended only to create comfortable seats. Such options are a practical decoration of the living room, where guests will comfortably accommodate. Also, non-folding sofas are found in the interiors of hallways, kitchens and dining rooms. Their benefits include:

• lack of a transformation mechanism (hence, nothing can break in them);
• long service life;
• stylish and aesthetic appearance.

Some people use sofas without transformation mechanisms for sleeping. It will comfortably accommodate one average person.

Mechanisms for transforming corner sofas

Corner sofa models are considered practical, functional and roomy. They are a real find for small apartments. Since they are distinguished by a large number of seats and a spacious sleeping bed. They are installed in the corner of the room (left or right) and occupy a minimum of free space.

Almost all transformation mechanisms are suitable for daily use of corner models. The Dolphin is considered an ideal option, as well as the Scissors model, which unfolds in several movements, and even a child can cope with this matter.

Which sofa mechanism is better

Since all sofa transformation mechanisms differ significantly from each other, the question arises before consumers: which sofa mechanism is better. Here it is worth starting not only from personal wishes and financial possibilities, but also from the purpose of the piece of furniture.

For daily use

For daily sleep, it is better to choose the following types of folding sofa mechanisms: accordion, eurobook, tick-tock, puma, dolphin. An excellent solution for every day would be a rotary or withdrawable mechanism.

If the product is bought for the purpose of regular operation, first of all, attention is paid to its design and the quality of the frame, which will be subjected to maximum load.

When choosing a sofa, it is important to consider the type of its filler. He might be:

• spring. In such a product, twisted springs are located inside in a vertical position. They, in turn, are divided into dependent and independent. The second option is more reliable, since such a filler does not bend, and during rest the spine is maintained in the correct position;
• springless. Differs in orthopedic effect, safety and convenience in use. Such products guarantee a sound and healthy sleep.

When choosing a sofa for daily use, you should pay attention not only to its folding mechanism and how it works, but also to the degree of mattress rigidity, upholstery quality, and the ability to change covers.

As a guest option

Compact models are used as guest sofas, which are laid out from case to case. Quite often, they are equipped with not very strong unfolding mechanisms (for example, a French folding bed), and it is not always comfortable to sleep on them. In these products, the main emphasis is on the spaciousness and convenience of seats, and the function of the bed in them is secondary.

Which sofa mechanism is the most reliable

Most people argue that the most convenient and reliable transformation systems are: roll-out, as well as straight and angled models that use such a type of layout as an accordion or a telescope.

When choosing a transformation mechanism, several factors should be considered:

• how much space does upholstered furniture take when folded and unfolded;
• purpose of furniture (for daily sleep or as a guest option);
• intensive load mode;
• ease of operation;
• frame quality.

A good product will:

• have an impeccable movement of the mechanism without any jamming when folding and unfolding;
• differ in high-quality assembly;
• lined with wear-resistant upholstery;
• resistant to high mechanical loads;
• differ in a strong and reliable frame.

In conclusion, it is worth noting that the quality of the sofa transformation mechanism directly affects its durability, practicality and ease of use. It is better to give preference to proven and well-established manufacturers with an impeccable reputation. Then the newly acquired furniture will please you with high technical characteristics, aesthetics and functionality.

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 aisles 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 landing 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. That's why all sofa models are divided into four main types according to the name of the transformation mechanism.

Withdrawable

The assembly 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 - as a sleeping place, a sofa can only occasionally serve, 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 - between the sofa and the wall there should be a distance of 10-15 cm, 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.

Manufacturers of upholstered furniture use a variety of layout mechanisms for sofas. There are no universal options. Depending on the method of operation, the size of the room and some other conditions, one or the other is selected.

In order not to make a mistake, you need to listen to the advice of experts. They will help you understand what factors you need to pay attention to in the first place. All groups of mechanisms are classified according to certain criteria. This makes it much easier to figure out which model is best suited.

studying, which mechanism for transforming sofas is better a number of recommendations should be taken into account. There is a generally accepted rule. All sofas are conditionally divided into guest types and designed for daily sleep. If the mechanism is chosen correctly, the furniture will last a long time. Its operation will be comfortable.

If the sofa will be laid out often (sleeping variety), you should not purchase products with a complex layout procedure. In this case, it would be useful to remember the golden rule: the simpler the better. Guest sofas, on the contrary, are not designed for the daily movements of the system. Therefore, their mechanism will not be as strong as that of sleeping varieties.

Attention should also be paid to such criteria as the maximum load of the bed, the orthopedic qualities of the model, its appearance, the layout procedure, the comfort of the bed, and also the convenience in the sitting position. That's why sofa transformation mechanism is an important factor influencing the choice.

Guest models

Guest type sofas have a design that does not take up much space. The appearance of such furniture is very unusual, interesting. Such mechanisms include "French folding bed", "Sedaflex", "Dionysus", etc. The main purpose of such furniture is to surprise guests, ensuring their maximum comfort during their stay in the hosts' house.

Comfort in a sitting position is important, but you won’t be able to kill two birds with one stone, you will have to sacrifice comfort when laying out. Corner sofa transformation mechanisms require a significant investment of time and effort in order to transform furniture into a place to sleep. First you need to remove the seat cushions. After that, the mechanism is activated.

If you believe the reviews, rest in such a bed leaves much to be desired. These types of sofas are usually cheap. You can sleep on them, but not all the time.

Sleeping sofa

The second group includes furniture designed for daily sleep. When laying out, you do not need to spend a lot of time. Sleep will be comfortable. Devices of this type include the "book" and its main variations. The most famous of them are "click-clack" and "Eurobook".

This type includes angular varieties. The most popular in this group is recognized the transformation mechanism of the sofa "dolphin", well, or"puma". Also bright representatives of furniture for daily sleep are sofas "telescope" and "ribalto".

Such mechanisms are very easy to operate. Their transformation is quick and easy. The sleeping place has sufficient rigidity. It is flat and comfortable. Such mechanisms are designed for a large number of transformation cycles.

"Book" or "click-clack"

One of the simplest is sofa book. Transformation mechanism involves raising the seat. At this point, a click occurs. The sofa comes back down already unfolded.

Click-clack models are a slightly improved version of the book. Such devices have an intermediate position. At the same time, a person can be in a “relaxation” position. The back does not go all the way down. Therefore, a person is located on the sofa half-sitting.

The advantage of the presented models is reliability and durability even with daily transformation. This option is ideal for apartments with a small area. Floor covering can be anything.

The disadvantage is the limitation in design, simple appearance. The back and seat of such models must be identical in length. A variety of "click-clack" should not be placed close to the wall.

"Eurobook"

One of the most common models today is the Eurobook. The sofa transformation mechanism is considered one of the most reliable. When folding, the seat is pushed forward. Under it opens a space for storing bed linen. The back rests on the vacated space.

The advantage of such a system is the minimum number of mechanical elements. Therefore, there is practically nothing to break in such furniture. According to consumers, these are durable reliable products. The sleeping area is very spacious. In addition, there is a rather large box below. It is convenient to store bed linen and bedding here. The sofa can be installed near the wall.

As for the disadvantages of such products, people note that the seat slides on the floor. Therefore, special attention is paid to the coating. In general, the "Eurobook" is a solid reliable mechanism that will serve its owners for many years.

"Pantograph"

One of the analogues of the "Eurobook" today is the "pantograph". The sofa transformation mechanism is also quite simple. It is necessary to raise the seat at an inclination of about 45º. Then it is lowered and pulled down and towards itself. The back goes down. This is how the bed is made.

Below is a laundry compartment. Some models of the presented variety can be transformed from a direct to a corner version of upholstered furniture. And it doesn't matter if you want to turn it right or left.

The advantage of this mechanism, judging by the reviews, is that the seat does not roll out on the floor surface. It simply slides out without touching the flooring of the room. The improved design causes an increase in the cost of such sofas.

"Cot"

The "clamshell" type has several popular design options. The principle of transformation here is simple. The bed is located directly under the seat. For the front panel, which is located below, the seat moves forward. There is a French and an American folding bed. Their principle is very similar.

The French one is pulled out in the form of a scroll, which unfolds in 3 stages. This mechanism is compact in size, so it is built into even very sophisticated sofas. However, this model is not used on a daily basis.

The American clamshell is designed for heavy loads. This sofa is practical and durable. However, this feature significantly raises the price of this furniture. To transform the sofa, you need to lift it a little, and then pull it towards you. This type of mechanism does not harm the flooring, but it needs to be lubricated periodically to avoid squeaks.

Withdrawable mechanism

One of the best options for sleep is considered roll-out sofa. Transformation mechanism here is very simple. The berth is obtained by rolling out additional sections from under the base. Due to its simplicity, the presented mechanism is called one of the most reliable.

Another advantage of such products is the absence of requirements for the size of the room. It is installed even in small rooms. Moreover, in the unfolded state, the place to sleep will be long and even.

The disadvantage of such mechanisms is the exactingness of the type of flooring. It should be strong, not sag under the weight of the sofa. In the process of transformation, the base slides on the floor. Nothing should interfere with this movement. It is better if the selected model of the presented type has rubber wheels.

Modern technologies help to modernize furniture paraphernalia. Thanks to them, simple sofas turn into a full-fledged bed, which can accommodate from 4 to 8 people. In addition, high-quality filler makes it absolutely safe for human health.

To date, there are several types of sofa mechanisms. Each of them has characteristic differences. Here, both positive and negative sides of such a design are distinguished.

Thanks to them, the transformation allows you to save enough free space. In our material, you will learn which mechanism is better and what needs to be considered in the selection process.
