What are the sofas. Sofa transformation mechanisms: pros and cons

Buying a sofa is a very responsible process, because such furniture is bought for more than one year. The choice must be approached with particular care so that the new sofa is comfortable for all family members, successfully harmonizes with the interior and pleases with its functionality for a long time.

First of all, the sofa is a comfortable relaxation area after a hard day, a place for friendly gatherings and watching movies. Often it is also used as a place to sleep. When buying, we usually pay attention to the appearance, but it will be much more important to make sure of the quality of the material and check the folding mechanisms of the sofas.

Before you go on a furniture shopping trip in search of a sofa, answer the following questions:

1. How much space do you intend to allocate for the sofa when folded and unfolded?
2. How often are you going to lay out the sofa?
3. In what mode will the sofa sleeper function: daily or as a guest option?
4. What load should the sofa withstand?
5. Do you need a special place to store clothes?
6. How much are you willing to spend on a purchase? Which model should you pay attention to: a budget option or a sofa with a more complex mechanism and reliable details?

Types of mechanisms, pros and cons

Types of sofas by folding mechanism:

• retractable, or withdrawable (on rollers): withdrawable, dolphin, eurobook, conrad, pantograph;
• folding: tango, book, elf;
• deployable: accordion, French cot, American cot, Spartak.

Let's consider in more detail each of the options.

Book

Having such a mechanism for transforming sofas, a piece of furniture is converted into 2 positions: a seated version and a sofa for sleeping. To turn the sofa into a sleeping place, its back is simply folded back. It will not have to be moved away from the wall during this process, since during installation it will be necessary to take into account that the design of the furniture requires a small gap between the wall and the back.

Parts of a sofa with a "book" mechanism are two metal or wooden frames with fixed or other soft filler. At the bottom, there is often a compartment for storing clothes.

Pros:

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

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

Tango

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

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

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

Eurobook

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

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

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

Dolphin

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

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

• comfortable bed;
• simplicity and ease of deployment.

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

Pantograph

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

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

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

Minuses:

• the mechanism is expensive;
• very wide seat.

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

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

Plus - when assembled, this sofa is very compact.

Minuses:

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

Roll-out sofa

The bed has two segments that are hidden in the sofa body. To unfold, you need to pull the bottom part so that it rolls forward. After that, the pillow leans back into the vacant space.

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

Minuses:

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

Accordion

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

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

Minuses:

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

Spartacus

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

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

Minuses:

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

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

Conrad or Telescope

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

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

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

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

Sedaflex (American folding bed)

Such a sofa unfolds like a French folding bed, but unlike it, it has not a three-fold, but a two-fold system and a thicker mattress.

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

Minuses:

• no storage box.

Elf

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

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

Minuses:

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

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

Pros:

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

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

Sofa with unfolding on the floor

The bed has two sections. When folded, they hide inside the sofa body. To convert such a sofa, you need to pull up on the inner edge of the seat. Then make a soft jerk forward and on yourself. The sleeping place does not provide for any supports and is laid out directly on the floor.

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

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

What to choose?

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

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

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

It is difficult for any of us to imagine a living room without a sofa. This soft component of the interior gives people a feeling of warmth and comfort, a sofa in any home occupies one of the most important places. On it, people relax, play, communicate with family and loved ones, as well as read, watch TV and sleep. In order to decide on his choice, you need to clearly understand what models exist and what functions they perform.

Now more and more new corner models and designs for the house are being produced all the time. In such a number of offers, it is quite difficult for the buyer to make a choice and understand which type is right for him. In most cases, a person chooses a model based on its appearance and the material from which it is created. But with such indicators it is difficult to achieve complete comfort in using the sofa. For example, such a choice is suitable for furnishing a room and giving it aesthetics, but not used often. For the same purposes, there are monolithic sofas, otherwise they are called non-folding. They can be seen in public places and shopping stores.

It is a completely different case when a sofa is bought for frequent use in everyday life. So, we can assume that such a model will be laid out every day for sleep. . To choose the right model and not to make mistakes, you should know and understand what are the mechanisms for transforming sofas.

You should also provide for other criteria for the model you choose: the size of the space required for the sofa, the ease of transformation, the availability of space where to put the bed linen. You should also determine for yourself which type of sofa is better.

The classification of all designs of sofas is carried out according to:

1. Transformations.
2. Design features of furniture.
3. Appointment.
4. Size and capacity.

Types of mechanisms

Names of sofas

Classification by purpose

All models can be divided according to their purpose:

1. Office furniture.
2. Living room furniture.
3. Kitchen furniture.
4. Hallway furniture.
5. Furniture for a children's room.

With all these varieties, sofas and their mechanisms will differ significantly from each other, so you should accurately determine the design of the sofa and its purpose. In most cases the purpose can be determined by the material of which the furniture is made.

Those sofas that are sheathed in leather or more budget materials are usually located in offices or kitchens.

Purchasing a new sofa is a major purchase that raises many questions and doubts. As with the choice of most pieces of furniture, the buyer wants to find a model that is equally comfortable, practical and stylish in appearance. The best way to choose the most comfortable sofa is to visit a furniture showroom and feel like the owner of a particular model.

• Some models of sofas are designed to perform only one function - they serve as a place to relax in a sitting position. These are the so-called guest sofas.
• Another variety are models that transform into a bed. When buying such a model, be sure to familiarize yourself with the mechanism of its operation to make sure that it is suitable for the conditions in which it will be operated.

Varieties

The folding mechanism of the sofa makes it easy and simple to turn it into a bed. Currently, there are many such options. However, before buying a sofa with any of the transformation mechanisms, you need to carefully study their properties, as well as find out what material they are made of. These characteristics will allow you to judge how long-term and comfortable the operation of the sofa will be. In the case of complex mechanical devices, the choice of transformation mechanisms made of reliable steel grades will be the most preferable option.

According to the type of layout, the sofa can be:

1. Turning, which is also called a transforming sofa or modular;
2. Folding, this category includes both folding sofas (French or American) and “Eurobook” sofas;
3. Withdrawable, which can be straight or angular;
4. with lifting mechanism, which happens on hinges, springs or can be carried out using a gas shock absorber system;
5. With walking mechanism, which is also called stepping; such designs include tick-tock, tango, and pantograph sofas, which are variants of the improved Eurobook model;
6. "Scissors"- most often these are corner structures;
7. "Butterfly", which is also called the "versailles" mechanism.

"Dolphin"

One of the most convenient and frequently purchased sofa layout mechanisms. The base of this sofa is on a retractable platform. While the design is in the form of a sofa, the platform is invisible, because it is hidden under its seat. In order to unfold the sofa, you need to roll out this platform and lift its edge a little up by pulling on the special loops. This will ensure that the surface of the platform is leveled at the same height as the seat. The resulting bed has an elastic base and a comfortable height.

Folding such a model is very simple: you need to pull up, holding the belt of the retractable base, it will rise and the mechanism will take it inside the roll-out platform. The platform itself then slides down under the seat. Such a mechanism is very reliable, allows you to get a comfortable resting place for two people, suitable for use every day.

Sliding sofas "dolphin" can be either straight or corner. In the latter case, they are supplied with a box for things located under the ottoman.

"Eurobook"

This layout is also known as "alternative". This folding model, in fact, does not have any mechanism that ensures its transformation, being an example of simplicity and reliability. The movement of parts of the structure occurs due to the rollers that move in the grooves of the base. This option is simple and suitable for long-term use.

To turn the eurobook into a bed, you need to remove the pillows and push the seat forward. Then it remains to lower the section, which was the back of the sofa, and you get a classic bed. To return the sofa to its original position, you need to do the same operations in reverse order: first, the backrest rises to its original position, and then the roll-out base moves towards it.

Under the seat there is always a compartment for storing bed linen, which is very convenient for the owners. Such models can be angular or straight type.

"Pantograph"

The mechanism called "pantograph" (also known as "Tick-tock" or "Tango") is an updated and improved version of the well-known "Eurobook". To turn this model into a bed, as in the case of the Eurobook mechanism, you need to push the seat forward. However, to do this, the seat must first be lifted up slightly by pulling on the hinges. Thanks to the folding mechanism, it will automatically take the desired position. The extended seat is placed on the floor and then the back of the sofa is lowered.

It turns out a wide and elastic bed on a spring block. The reverse transformation can be done by putting the backrest in the normal position, and then lifting the seat and moving it close to the backrest. The mechanism is designed for daily use. Sofas of this type are suitable for those who have high pile carpets at home, because the transformation takes place without moving the furniture directly on the floor.

In the case when the model with the pantograph mechanism is angular, it has a box for storing bedding.

"Puma"

A very simple and softly working spring mechanism of sofa expansion, which in terms of smoothness of movement really resembles the steps of a wild cat, after which it is named. During the transformation, the seat of such a model rises and, as it were, takes a step forward. In order to do this, just pull on the loop mounted at the bottom of the seat. At the same time, an additional platform hidden there will move out of the depth of the sofa, which, having taken the vacant seat, will transform the sofa into a full-fledged bed. This transformation occurs through a single movement gently and smoothly, which is facilitated by properly selected springs, equipped with a synchronizer.

Folding this model is also very simple. The folding process is carried out in one movement, for this the same sewn-in loop is used. Raising the front of the bed with it, you need to make a slight push back to the back of the sofa, and the built-in mechanism will lower both platforms into place. This mechanism is ideal for everyday use.

A straight sofa-"puma" does not allow to have a place for storing linen in the design, however, in the corner modifications, equipped with an ottoman, such a compartment is present.

"Conrad"

This type of transformation is also called high-rise roll-out.

The mechanism consists of three fragments, folded compactly packed in the back of the sofa. The outermost part of the bed is a frame structure, the middle part is a platform, completely standing on the floor and serving as an assembled seat, the head part is in the back.

When laying out such a sofa, you do not need to remove soft pillows, they will not interfere with pushing out of the depths of the structure and installing three retractable parts. The frame part is pulled out to the level of the legs first, it pulls the seat behind it, which, moving, gives impetus to the extension of the head of the bed. Special rollers with brackets moving along hardwood guides and a well-oiled mechanism allow such a transformation to be carried out without much effort. In order to fold the “konrad”, you need to lift the frame part by the built-in loop and push it towards the back.

However, with everyday use, such a model may not seem very convenient in the layout. This will be especially problematic for a woman or a child, since the retractable parts are of considerable weight.

The advantage of this model is its compact and elegant appearance, the creation of a comfortable and reliable bed without kinks and the presence of a box for storing linen built into the back.

Since the Konrad mechanisms are not produced in the Russian Federation, this affects their cost: sofas with similar components have a fairly high price tag.

Transformer

This is a sofa with a swivel transformation mechanism, which is also called "scissors". Usually these are large corner sofas with an ottoman. Outwardly, they are not too distinguishable from corner sofas of other designs, but if you look closely, it becomes clear that the ottoman of such a model has a slightly longer length than usual. With the pillows removed, its length will be about 190 cm, thus this part of the structure can simultaneously serve as a sleeping place without any additional transformations.

If you move the main part of the seat at an angle of 90 degrees and move it close to the ottoman, you can get a full-fledged sleeping place, already designed for two people. For ease of movement on the floor, the sofa-transformer is equipped with rubberized wheels. For reliable fixation, the wheels are equipped with brakes, which are installed as needed.

You can move the seat not only close to the ottoman, but also in the opposite direction, getting a U-shaped design. For some models of transformers, the back is additionally lowered, so the buyer can choose exactly the option that seems optimal to him. Each of these models has two spacious storage drawers and is an alternative to the usual roll-out sofas.

"Accordion"

The accordion folding mechanism is strong and durable, when unfolded, it turns the sofa into a full-fledged bed. It works on the principle of an accordion, for which it received its name.

When assembled, it has a double-fold back, which, when unfolded, straightens and creates the basis of a bed. In order to unfold the "accordion", the seat is lifted slightly up (until it clicks), then the mechanism begins to move forward, stretching the back folded in half. For stability and reliability, such models are usually equipped with armrests.

Assembling the "accordion" takes place without much effort, but requires some skills. In order to start the assembly mechanism, you need to lift up the extreme part of the structure and push it towards the back: the "accordion" will curl up.

This model is usually straight, has a box for storing linen, when folded it is very compact and takes up a minimum of space. Such models are designed for daily layouts.

"French" folding bed

The transformation mechanism called the "French" clamshell has a second name: such designs are called "mixotual". This is the so-called metal frame mechanism. It consists of steel tubes of various thicknesses (in domestic designs it is 1.5 mm, in imported ones - 0.8 mm), an awning made of durable fabric (most often it is polypropylene) and equipped with transverse support strips - "armor" (made bent plywood) and equipped with a polyurethane foam mattress, which is in a fabric cover.

When laying out and folding, the mattress remains inside the structure, since it does not have its own frame. To open the "mixotual" almost no physical effort is required, for a start it is enough to pull up and forward the very frame of the mechanism, which is also the edge of the seat of the sofa. Then the whole mechanism must be lifted up and “rolled out” forward, like a regular clamshell. At the same time, sections folded into each other will straighten out, each of which is equipped with folding legs-supports made of metal semicircular tubes. Thus, a sleeping place is laid out, designed for a weight of about two hundred kilograms and dimensions of 185 * 145 cm. Sofa cushions are removed before transformation.

When assembling, the outermost segment of the structure first rises, which is “wrapped” onto the middle one, and then both of them are placed on the base of the sofa. The mattress is not removed, but bed linen, pillows and blankets must be removed to avoid damage to the mechanism.

"French folding bed" is a convenient and easy-to-transform mechanism, designed for use from time to time, the so-called guest version of the bed. In many respects, the duration of the service life of this model depends on the quality of the steel fittings located at its base, the reliability of the slats and the density of the awning.

"Sedaflex"

This mechanism has another name - it is often called the "American" clamshell.

This design is copyrighted by Sedac, hence the name "sedaflex". It is an improved version of the “mixotual”, while the mechanism is not divided into three, but only into two parts. Another innovation is the filling of the mattress with a spring block, which increases the comfort and stability of the bed. Thicker tube-legs, which have a thickness of 3 mm, also contribute to reliability.

Another advantage of the "American" is the fact that sofa cushions do not need to be removed before transformation. The design is designed in such a way that when laying out the sofa, the pillows turn over, ending up on the floor, and thereby increase stability and save time and space for the owners. Also, as an advantage of the "sedaflex", we can mention the fact that it was decided to replace the reiki-lats in it with elastic belts.

The transformation of the "American clamshell" is similar to the transformation of the "mixotual", both models are laid out forward with the help of physical effort. By pulling the edge of the seat of the folded sofa, it is lifted up a little and the entire structure is laid out with a fixed mattress.

The dimensions of the Sedaflex are somewhat larger than those of its French counterpart, which contributes to the greater popularity of this particular model.

A box for storing linen is not provided in any of them, since the entire internal space in the sofa is occupied by the mechanism itself. However, if the clamshell models come with an attached section, which can be located on either side, then in this section it is possible to place linen for storage.

"Telescope"

This mechanism got its name due to the resemblance to the unfolding of a telescope. When it is implemented, the transformation occurs as follows: first, pulling on the mounted hinges, the lower tier of the structure, previously hidden under the seat, is rolled out. This will be the basis for the bed, or rather, the part where the legs of the sleeper will be located. When extended, it will pull the platform behind it, which will become the middle part of the base of the bed.

To assemble the structure, the spring block is first returned to its original place, then the lower part of the sofa is pushed in. It is worth noting that in the first pull-out section there is a place for bed linen or clothes.

One of the disadvantages of the telescopic design is the fact that it is not suitable for a large sofa. First of all, these are two- or three-seat sofas that are good for a nursery.

How to choose?

Any sofa, even folding, even non-folding, has similar design features that must be considered when choosing:

1. There are no standard sizes for them. The height, width and depth of such upholstered furniture vary depending on the type of sofa layout and whether it is angular, straight or modular.
2. When purchasing such furniture, you need to take into account the size of the room: the model for daily sleep should fit freely in the room in the unfolded state.
3. Types of such sofas are divided into straight and angular. The latter can have different angles: left, right or the so-called universal angle.
4. You can choose either a model for every day, or a guest option, for this you need to decide how often you need to transform the sofa into a bed.

Immediately before buying, it is advisable to visit furniture stores in order to “live” inspect various models and personally check how convenient and easy the transformation mechanisms work. At the same time, you should not stand and observe the process of unfolding the sofa by a consultant, it is better to ask the seller to show the layout principle and then do this procedure with your own hands. Only in this case, you can understand whether it will be convenient to perform such actions daily.

For every day, it is better to choose the most easy-to-transform mechanisms, such as, for example, “Eurobook”, “telescope”, “pantograph”.

The service life that a sofa will withstand without repair depends entirely on the quality of the materials from which its base, body and folding mechanism are made.

Be sure to make sure that the interior of the sofa is made of solid wood, and not chipboard or plastic, because in this case they can deform and crack. The quality and type of wood is also very important. Softwoods such as pine are cheap and are used in inexpensive sofas, but they can warp or dry out after a while, usually after five years. More expensive woods, such as kiln-dried oak, ash or beech, will make the sofa durable and keep it beautiful.

Therefore, be sure to carefully ask the consultant and carefully examine the inside of the sofa. In this case, it is worth paying attention to how the joints and joints are attached. It is important to remember that the design, in which the constituent parts will be held with screws, dowels or on special furniture pegs, will last much longer than the one whose parts are fixed to each other only with glue or fixed on simple self-tapping screws.

An important factor when buying a folding sofa, of course, is the availability of space in the apartment for its transformation. If you have limited space, but need extra beds, then instead of one huge sofa, it would be preferable to purchase two small folding sofas.

In addition, the firmness of the sofa mattress is another important factor to be taken into account when choosing a model. This largely depends on personal preference. But, as a rule, a firmer mattress will be healthier, and when using this sofa as a bed, it will make it possible to get a good night's sleep.

The next important factor is the elasticity of the sofa. It also has to do with personal preference and choice. Some people don't like bouncy sofas, and some don't. In order to evaluate the future acquisition from these positions, it is worth sitting on it even before the purchase, and it is even better to lie down.

If there are animals in the house, which, of course, will certainly be happy to lie on a brand new sofa, it is worth choose your upholstery carefully. Contaminants such as pet hair and fluff are well removed from flock and leather, but get stuck in the tapestry; on such a coating as a shinil, there are puffs left from their claws.

And finally, the weight of the sofa is another important aspect that the buyer should consider.

Folding models of upholstered furniture have practically ousted other options from the market. Their versatility and practicality form a steady consumer demand. Responsible for these characteristics are the mechanisms for transforming sofas, which are being improved every year thanks to the innovative developments of specialists. Modern upholstered furniture has become more reliable and durable. And now a fragile woman and a child can turn it into a full-fledged sleeping place without any problems.

Purpose

Folding sofas are necessary to save usable space in the room. They can be used as the main bed, and the universal model will help out if guests arrive. During the day, such furniture is usually in a folded position and performs its direct functions.

The design, dimensions and folding mechanism determine the function of the sofa in the interior. For example, "Click-clack" requires more space against the wall, and "Tango" will take over the functions of the main bed in the nursery.

You can count several dozen modern mechanisms for transforming sofas. Each of them has its own design features and advantages. At the same time, the basic device of any sofa is approximately the same. Upholstered furniture consists of several basic elements:

• back;
• seat;
• armrests;
• frame;
• filler;
• upholstery.

In addition, it can be additionally equipped with pillows or drawers for storing bed linen and other things. The transformation device is a set of parts that includes a articulated lever mechanism, guides and rollers. Its main task is to increase the area of ​​\u200b\u200bthe bed. Usually the design is placed in the back and middle blocks of the sofa.

Overview of popular models

All types of sofas differ in several ways. By design, they can be angular, straight, modular. By the number of places - double, triple and more. Also, the furniture is equipped with a different mechanism for laying out sofas.

Depending on these criteria, products differ:

• dimensions;
• convenience;
• bed size;
• design.

Having studied the design features and clearly knowing your own needs, you can make a smart choice. First of all, it is necessary to take into account the regularity of operation - whether the furniture will be laid out daily or from time to time. In the first case, the most reliable mechanism is needed. And in the second, the main thing is that the furniture fits into the interior when folded.

Books

The most common type of upholstered furniture. By design, products can vary significantly, but the basic principle remains the same - the design of the sofa allows you to fold and unfold it like a book. The furniture consists of two halves moving relative to each other, which provide for two or three positions. To fix the sofa in any of them, just pull one of the parts towards you.

There are several types of this mechanism:

1. The usual "book" is the oldest of the existing models. Identical furniture options were still sold in Soviet stores. They have only two fixed positions and a simple transformation mechanism. This model is budget friendly. Inexpensive fabrics are used for upholstery, chipboards are used as a frame. The main drawback is the insufficiently even and spacious surface for sleeping. In addition, a similar mechanism for a sofa implies that the product will have to be constantly moved away from the wall. This is quite difficult, given that ordinary "books" are often equipped with storage boxes.
2. "Eurobook" differs from the usual "book" in that it does not need to be moved away from the wall. The folding mechanism allows you to roll out the front part, then the back fits into the resulting opening. The furniture is characterized by more impressive dimensions, it can comfortably accommodate two people. The sofa with the Eurobook mechanism can be used as a comfortable bed for one person, even when folded. The cost of such furniture is much higher than that of the previous model.
3. "Tango" ("click-clack") - options that are comfortable for sleeping, the main feature of which is the absence of a pronounced joint between the two halves of the "book". The furniture looks like a single whole, both folded and unfolded. The model is often equipped with armrests, which, when unfolded, can be lowered and raised at an angle in the form of a headrest. These types of sofas are often used as beds, that is, they are not folded in the morning.
4. Pantographs are the most complex mechanisms of "book" type sofas. There are several varieties of them. You can unfold the "Puma" sofa in one motion, without using rollers (which means that it is impossible to spoil the floor). The seat is pushed forward, the backrest is lowered, at the same time the legs of the support are lowered. You can fold everything back with the help of special handles. The pendulum device underlying the "walking eurobook" allows furniture to be transformed by simply pulling on the loop. To unfold the model with the tick-tock mechanism, it is enough to pull the seat towards you and slightly up and gently lower the structure to the floor.

Among the advantages of models equipped with a "pantograph" is the smoothest movement of the mechanism among the "books".

Roll-out structures

The roll-out mechanism means the presence of wheels. Part of the structure - two segments - in the folded state is inside the sofa. In order to spread out the furniture, it is necessary to roll out this half from the body, and then raise it flush with the seat. The quality of the videos is key.

Clamshells

The transformation of any "clamshell" occurs according to the principle of familiar furniture of the same name. The "French folding bed" in the unfolded state looks a bit like the Soviet model. You just need to stretch three sections forward, and it will stand on the metal supports hidden in the body. This is a lightweight, but quickly wearing mechanism, which can be mechanically damaged if the weight of the sleepers is too large.

Some of the problems were solved in the "American clamshell" model (sedaflex). It differs from the French one in that the transformer mechanism does not stretch out, namely, it unfolds according to the principle of a sandwich. First one section folds out, then another. Between them are supports. When installing sections on supports, a berth is obtained. This is one of the most convenient and reliable mechanisms for transforming sofas.

The main drawback of the "American clamshell" is the lack of a storage system. Inside the sofa is only a bed.

Accordion

In a way, this is also a clamshell. But if the latest types of transformation mechanisms hide additional sections at the bottom of a piece of furniture, then the “accordion” is in the back, which consists of two sections. For unfolding, it is necessary to push the lower part forward, and the back will decompose.

When folded, the "accordion" looks attractive and compact. And the absence of a mechanism at the bottom makes the sofa more reliable. Drawers for linen are not provided in the model, so it is often equipped with additional cabinets. The sleeping surface is flat, but its size is limited by the height of the back. Another significant drawback is the possibility of damage to the flooring during the transformation process.

Sofas equipped with a mechanism such as "accordion" are not very popular, so you won't be able to immediately find a model of a suitable color and size.

Folding sofas with metal frame

Models on a metal frame are more difficult to manufacture, more expensive. But if all the connecting nodes and mechanisms fit exactly, such sofas can last longer. The frame is based on shaped pipes, and cushions are placed on a metal mesh up to 0.5 cm thick. Due to the increased strength, such a frame is the most reliable for daily use.

Spartacus

"Spartak" is equipped with a mechanism that unfolds forward. The triple folding device is somewhat reminiscent of the "American clamshell", that is, it unfolds in three stages, standing on the supports inside the frame. An additional advantage is the presence of a polyurethane foam mattress and a metal mesh base, guaranteeing a comfortable sleep. Such elements are recommended by orthopedists for people who have problems with the musculoskeletal system.

In the Spartak models, not just a reliable transformation mechanism, such sofas are designed taking into account medical recommendations.

Elf

Sofas "Elf" with a metal frame have an orthopedic effect. An additional plus - models with a stepper mechanism increase the usable area of ​​\u200b\u200bthe bed due to the sections located at the bottom of the piece of furniture or in the back. And the "Elf" is laid out due to the armrests. They are bred on the sides - the design becomes longer. The frame is made of profiled pipes. The base for the pillows are curved wooden transverse slats.

The most complex and functional products

Sophisticated models of folding sofas are equipped with universal mechanisms and electronics that allow you to give the sleeping position the most comfortable position for a particular person. Among all types of folding furniture according to the type of transformation, the most multifunctional can be called the modification options "recliner". They are equipped with a control panel that allows you to fix the footrest at the desired angle, push it only a certain distance. The backrest angle is also adjustable. Recliners are supplied with vibration massagers. Smart models with electronics can remember settings. The disadvantages of recliners are obvious. They are expensive, in the event of a breakdown, repairs will also cost a round sum. In addition, this is more of a place to relax, not to sleep - there is no full-fledged sleeping surface.

Even a superficial acquaintance with what the sofa folding mechanisms are like leads to the conclusion that there are no universal tips for choosing. It all depends on many factors:

• housing conditions;
• frequency of use;
• financial opportunities;
• the required sleeping area.

It is definitely impossible to answer which sofa mechanism is better. Each has certain advantages and disadvantages. Simplicity of design can be a plus when it comes to constantly using an inexpensive mechanism. And a disadvantage if the main criterion is the comfort for sleep.

Expensive models equipped with an electric drive and a vibration massager will help you relax after a working day. But sleeping on them is hardly more comfortable than on a regular "book", which is much cheaper. In addition, the simple mechanism of the sofa is the most reliable, because there is nothing to break.

For regular sleep, it is better to choose a reliable and comfortable model of upholstered furniture. As a guest sofa, you can use a design that occupies a minimum of usable space.

In the store, you need to check the serviceability of the transformation mechanism. It should not make extraneous sounds or jam. To determine the quality of the assembly, you need to try to expand and fold the furniture several times.

Before giving preference to a particular model, it is worth deciding how exactly it will be used, prioritizing. Only then will it be possible to make an informed and reasonable choice. A wide range will allow you to purchase a product that meets all requirements.

The choice of sofa depends on living conditions and the frequency of use of the product.

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

But it is a completely different matter if the purchase of a sofa is made for use for every day and preferably not for 1 year. Usually in this case it is assumed that he will be laid out daily for sleep. In order not to make a mistake with the choice, it is important to know what are the mechanisms for transforming sofas.

Description of types of transformation mechanisms

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

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

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

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

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

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

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

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

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

Types of sofas by shape, design and purpose

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

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

Straight models are a classic

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

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

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

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

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

Transportation principles

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

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

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

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

Conclusion

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