People are often faced with the need to dismantle furniture themselves. Every craftsman should know how to disassemble a sofa; this information will be useful during a move or renovation. In order to carry out dismantling without damaging any parts, you will need special skills and basic knowledge about the design of the product.
Why is it important to choose the right sofa transformation mechanism?
- The mechanism is one of the main structural components of the sofa, therefore the overall service life of the transformable sofa depends on its reliability.
- The mechanism affects the convenience and ease of converting the sofa into different positions.
- Depending on the transformation mechanism, different free spaces in the room will be required to bring the sofa into the desired positions.
- The shape of the sofa also depends on the type of transformation mechanism. After all, it is under it that the mechanism is hidden from our eyes.
Now let's get down to specifics. Next, I will present various mechanisms for transforming sofas and describe their positive and negative sides. Let's go!
Sofa book
This species is named so because of its principle of transformation. Initially, the sofa is assembled, with the backrest perpendicular to the seat. This is a classic day uniform. In this position the sofa is suitable for comfortable sitting. It can comfortably accommodate several people at once. Once opened, the sofa turns into a place to lie. It takes up more space. When opened, it is intended for sleeping.
Sofa book
During intermediate opening, a special cavity is formed in the sofa, intended for storing things. Most often, bed linen is placed in it. The size of the box is considered quite roomy. Thanks to its presence in the room, it is possible to further save space, making the book-type sofa as functional and comfortable as possible.

Transformation
For everyday use, the sofa is in the folded position. This way it takes up less space, leaving more free space in the room. The transformation mechanism of the book sofa is extremely simple. It is enough to pull the seat up until a specific click is heard. Then the back will lie perpendicular to the floor. After this, the seat can be lowered to its original position. As a result, a large platform is formed on which a person can lie down comfortably. In this form, the sofa will resemble an open book.
Mechanism for transforming a sofa-book
The intersection of the back and seat will move to the center of the base. For this reason, the sofa will take up more space in the room. Its location close to the wall of the room is unfavorable. This is due to the fact that when opening the sofa you will have to move it back each time.
Peculiarities
This type of sofa is one of the most frequently chosen. This is primarily due to the cost of such models. Book-type sofas are one of the most affordable models with a transformation mechanism. It is also worth noting the fact that the design includes a special compartment for storing bed linen, which is also a plus.
Sofa book in the interior
One of the disadvantages is the insufficient ergonomics of the model. Due to the specific layout mechanism of a book-type sofa, it is inconvenient to place it close to the wall. After all, you will have to constantly push it back. And the transformation system itself is quite simple, but you need to make an effort to open the sofa.
You can very often find a sofa book in the interior of a home. This is due to its convenience, functionality and low price. These three factors completely eliminate the shortcomings of the product. Therefore, a sofa book is an excellent purchase for a living room or recreation room.
Sofas without transformation mechanisms
By definition, such sofas do not contain transformation elements and are not capable of folding out. Sofas without mechanisms are used to create seating for two or more people. You can offer this option for a sofa in a small living room. Less often they can be found as a sofa for sleeping. Although for people who are not overweight, using a sofa in this capacity is quite acceptable.
Sofas that cannot be folded out can be used as separate sofa modules. By using several similar modules, especially of different sizes, you can change the shape of a sofa made up of modules.
A monolithic sofa is suitable for the hallway, for the living room and will 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.
Cons: no mechanism, no possibility of converting the sofa. Monolithic sofas are not suitable for organizing sleeping places, especially if you need to sleep two or more people.
Types of sofas
The nuances of the accordion mechanism make it possible to produce a wide variety of sofa formats. In addition, with the help of this system, chairs are created that you can also sleep on. For additional convenience, the design includes massive armrests - made of solid wood, or covered with fabric with a soft lining.
Pros and cons of sofas with the Sedaflex mechanism, selection criteria
Today you can find several types of sofas with an accordion mechanism:
- Straight - folds forward, creating a double space. When folded, there are three seats. This sofa is suitable for both compact and spacious rooms, it all depends on the location of the furniture.
- Corner - designed to fill corners that are usually empty due to the complexity of building furniture. Such sofas have a main and a corner part, and they are equal in length. The main part of the seat folds out to complement the corner and create a spacious sleeping area.
- A chair-bed is not quite a sofa, but due to its compactness and the ability to create a sleeping place, this option is very popular. It is best suited for small homes that often have guests.
In stores you can often find sets of sofas and folding chairs, made in the same style.

Transformation mechanism for the sofa “Book”
The “Book” sofa can be folded out into two positions: a sitting sofa and a sofa for sleeping.
The sofa can be converted into a sleeping position by tilting the back of the sofa back.
When unfolding, you won’t have to move the sofa away from the wall, but you need to take into account 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 spring blocks, another filler can be used - foam rubber or latex. A sofa with a spring block is preferable, as it has better service life and comfort.
The “Book” sofa often contains a section for bed linen inside
Advantages : durable, reliable, time-tested mechanism. Suitable for frequent use and organizing a sleeping area.
Disadvantages : the sofa can only be reclined in two positions - sitting and lying down. During transformation, a bulge or depression may appear in the part where the folding parts of the sofa are connected, 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.
Sofas with “Telescope” transformation mechanism
If you need a small sofa that, when unfolded, would form a full-fledged sleeping place, then, undoubtedly, sofas with a “Telescope” transformation mechanism are the ideal choice. This design allows you to place two or three sections of the bed in a small compact sofa. How can this be? Surprised! But this is not a joke. Sofas with a “Telescope” device store two-thirds of the berth under the seat and another part is hidden in the back. It may seem that such a design will create a lot of trouble when unfolding. However, it is not. Telescope sofas have another advantage - efficiency and ease of transformation . It is enough to make a couple of simple movements and your cozy sofa will turn into a spacious bed. Have a nice holiday!
Happy shopping at the EkolMebel salon!
Transformation mechanism for the “Tango” sofa
When preparing this article, I came across the fact that manufacturers come up with their own names for mechanisms of the same type in terms of properties. This causes confusion. This is the case with the Tango mechanism.
The “Click-clack (clack)” mechanism has similar properties. In fact, both mechanisms are similar to the “Book” already described above.
The main difference from the “Book” is the ability of the “Tango” (“Click-clack (clack)”) to take intermediate positions of the back of the sofa when unfolding.
In addition to full horizontal folding, the backrest can be in a half-lying, half-sitting position. This opportunity creates additional comfort for relaxation.
Tango sofas have a section for storing beds
Advantages: the mechanism allows you to fix the back of the sofa in several positions, “Tango” sofas are small in size, and when folded flat, the sofa creates a surface without unevenness or bumps.
Disadvantages: it is not possible to place the sofa tightly against the wall; when transforming, the backrest needs space to fold out.
Features of the telescopic transformation mechanism
The folding mechanism is simple and convenient: disassembly and assembly is performed in a few movements, which even children can handle. When unfolded, individual elements of the sofa resemble retractable parts of a telescope. Reliable casters ensure ease of movement. Unfolding is performed in the following order:
- By pulling the seat towards you, ensure that it extends and at the same time the headrest of the bed appears from behind the backrest.
- Filling a niche with an additional seat.
To fold, you need to install the additional seat in place, and then simply push the structure back.
Telescope sofas are available in straight and angular versions. Corner models are equipped with an additional module, under which there is a deep linen drawer. The popularity of such models is explained by the thoughtfulness of the details and design, taking into account the anatomy of the human body for a comfortable rest:
- High backrest, the angle of which is selected for optimal neck support.
- Dorsal and popliteal rollers;
- Soft supporting armrests.
The secret of the convenience of telescope sofas lies inside the middle section, hidden under the drawer when folded.
Transformation mechanism for the Eurobook sofa
Mechanism operation : the seat of the sofa moves forward on roll-out rollers, forming a niche in shape and size identical to the back cushions of the sofa. The pillows are placed in a niche, resulting in a flat surface for the sleeping area.
Advantages : ease of converting a sofa into a bed, simplicity of the mechanism itself - read its high reliability, large and flat place to sleep, large niches inside the sofa for storing things and a bed. Disadvantages : due to the wide seats, it is not comfortable to sit on the sofa leaning against its back, especially for people of short stature.
Transformation mechanism for the sofa “Pantograph” (“Tick-tock”, “Puma”, “Walking Eurobook”)
The story with the “Pantograph” is the same as with the “Tango” sofas. Apparently, for the sake of catchphrase, sellers and manufacturers came up with a number of bright names for essentially the same mechanism. So, what else did we manage to find under the guise of a “Pantograph” - “Tick-tock”, “Puma” and even “Walking Eurobook”. To avoid confusion, I will further call the mechanism “Pantograph” (it sounds somehow solid and mysterious))) .
The “Pantograph” arose as a variant of the “Eurobook” mechanism. The difference is that the “pantograph” does not have roll-out rollers. Otherwise, it has similar parameters to the “Eurobook”. It is equipped with internal niches for storage, and has a large and flat sleeping area.
Principle of operation of the mechanism : To unfold it, just pull the sofa seat up, grasping its edge in the middle. Often sofas are equipped with hinges - handles for ease of unfolding. By pulling the sofa seat up, 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 back cushion is placed in the resulting niche. The result is a flat, without visible joints, place for two people to sleep.
Advantages : sofas with “Pantograph” have a comfortable place to sleep. The mechanism is easy to unfold. Such a sofa will not spoil your floor covering because when unfolded, parts of the sofa do not move on the floor.
Disadvantages : the mechanism is expensive because of this and the cost of the sofa becomes higher. Due to the wide seat, it is not comfortable to sit on the sofa; you need to use additional pillows
The procedure for transformation to the “bed” position and back
- The assembled sofa is visually practically no different from its counterparts.
An assembled sofa with a dolphin mechanism can be quite tall - In some models, the upper cushions are removable, in others they are not at all. The transformation of upholstered furniture with the “dolphin” mechanism into the “bed” position and back is carried out literally in one movement without applying significant effort.
Removed pillows need to be placed somewhere while you sleep. - To unfold, you first need to roll out the lower part of the transformer, using the loop, handle or protrusion provided for this, depending on the specific model. The sections roll out all the way (sometimes with a characteristic click).
The hidden section moves along special guides - The lower part needs to be pulled up and towards you. The half will be fixed at the same level with the other pillow.
The loop handle is usually “disguised” as the main color - As a result of the manipulations, you get a flat and wide sleeping place, on which you can comfortably rest. The sofa is assembled in the reverse order: the pull-out part is lowered, the sections are rolled under the sofa, and the pillows are put in place.
In the “bed” position, the mechanism is securely fixed

Mechanism for transforming the sofa “French folding bed”
How the mechanism works: The sleeping surface of the sofa consists of three sections. You need to pull the edge of the seat and stretch them forward. The sections will open and stand on legs - supports. When folded, the sections are hidden inside the sofa body.
Sofas in this series are not suitable for frequent use since the mechanism is quite weak in terms of wear and tear.
It is not recommended to sleep permanently on “Folding beds” since the sleeping surface contains uneven surfaces and has poor orthopedic characteristics.
These sofas don’t even have space to store a 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 to unfold it you will need free space (at least 1.50 meters) in front of the front of the sofa
Advantages : when assembled it is small in size.
Disadvantages: uncomfortable sleeping surface, no places to store the bed, short service life (about five years)
Conclusion: you can use the “French folding bed” to organize seating and for rare use as a sleeping place - an option for unexpected guests to stay late (they won’t sleep on such a sofa for a long time and will soon run away))).
Pros and cons of the accordion mechanism in sofas
Sofas with an accordion mechanism are in great demand among consumers. They are provided by various manufacturers in a wide range, allowing each buyer to choose exactly the option that best suits the interior of the living room, nursery or bedroom.
The main advantages of the accordion sofa include:
- Ergonomic and compact when folded.
- Large sleeping place with a length of up to 2 m when unfolded.
- Durability and reliability.
- Long service life.
- Easy to unfold and fold.
The accordion folding sofa bed is suitable for daily use as a sleeping place.
As for the disadvantages, we should add to them:
- the presence of a thick back, which does not always look stylish and modern in interiors;
- lack of a separate backrest. That is, when the sofa is folded out, the back goes into the sleeping area;
- no wheels. If the room has laminate or other covering that is susceptible to mechanical stress, the legs of the sofa will easily scratch it;
- When unfolded frequently, metal frames may begin to creak.
Sofa transformation mechanism American folding bed (Sedaflex, Sedaflex)
The principle of operation of the mechanism: The sleeping place has three parts - sections. You need to pull the seat of the sofa, as a result of which the sections of the sleeping place will open and stand on supports. The unfolding takes place in two stages - first one section will open, followed by the next one.
In essence, this mechanism is identical to the “French clamshell” mechanism.
Its main difference can be called reliability.
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 use, has good reliability and durability.
Disadvantages: there is no place for linen, the surface of the sleeping area has seams.
Mechanism for transforming the sofa “Italian folding bed”
This transformation mechanism belongs to the double-folding mechanisms, just like the American clamshell. A double-folding mechanism is a mechanism that is brought into working position in two steps.
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).
- In the first step of unfolding, the back of the sofa, together with the pillows, tilts forward and then lies down and rests on the seat of the sofa.
- At the second stage, the inner part of the sofa structure rotates around its axis, this is reminiscent of the unwinding of a rolled mattress. After this reversal, the support legs are revealed; the previously hidden ones were hidden and folded inside the structure, and the resulting sleeping area of the sofa rests on them.
Due to 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, this became possible thanks to the use of reinforced metal pipes in the frame of the mechanism, the sofa when folded has a compact size, when unfolding there is no need to remove the pillows from the seat of the sofa, Italian folding beds have the most a thick and comfortable mattress for sleeping; in addition, the frame uses slats and belts that create an orthopedic effect.
Disadvantages: lack of storage space for linen, high price
In terms of ease of use and orthopedic properties, this type of mechanism is most suitable for a sleeping sofa for daily use.
Transformation mechanism for the sofa “Accordion”
Principle of operation of the mechanism : “Accordion” acquired its name for its similarity to the principle of operation of the bellows of an accordion (they stretch back and forth). The sleeping space of the sofa also seems to stretch, moving forward, when the sofa is brought into the sleeping position, and rests on the extended supports. After the transformation We have a flat, although with minor seams, a spacious place for rest and sleep.
The convenience of the “Accordion” sofa is in its compact size when folded. But we must not forget that to unfold the sofa you will need free space in front of its front part (you need at least 1.50 meters)
Accordion models are often equipped with an additional cabinet for storing bedding. This 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, which increases the service life of the sofa. Comes with additional storage cabinets. Ease of moving the sofa into a sleeping position.
Disadvantages: the sofa, when placed in the sleeping position, moves on the floor, so it can damage the floor covering.
Sofa "Accordion"
One of the most popular mechanisms for transforming a sofa is the “Accordion”. Its main difference is its maximum compactness. The entire main part of the opening system is built into the backrest. Therefore, the “Accordion” sofa, when unfolded, increases significantly in size. At the same time, it becomes an excellent place for a person to lie down.
Sofa “accordion”
Opening principle
The sofa itself is divided into several parts: a seat, a double back and a base. Everything is placed as compactly as possible; as a result, the entire structure does not come out in any way when closed. All system components are involved in unfolding.
In order to open the sofa, you need to pull the center of its horizontal base, first lifting the seat. Eventually it will install on him. When the structure of the sofa is almost open, you should press on the place where the two surfaces of the backrest fold.
The principle of opening the sofa “accordion”
As a result, the system will increase significantly in size. The opening principle resembles the operation of an accordion. Therefore, the sofa layout mechanism is named after a musical instrument.
Distinctive features
The popularity of this type of opening near the sofa is due to several points. The main one is the overall ergonomics of the design. When unfolded, the sofa increases significantly in size. In this case, the rear part does not move beyond its limits. For this reason, the sofa can be installed close to the wall or even in the corner of the room. It is perfect for small rooms and spaces, as it is much smaller when folded.
A sofa with an “accordion” transformation mechanism can be installed against a wall
But along with the advantages, this model has several disadvantages that you should familiarize yourself with. Most Accordion sofa configurations do not have a drawer for bedding. This is due to the fact that almost all of the internal space is occupied by the folding mechanism. It also requires additional care and lubrication. Otherwise, the service life of the sofa will be shortened.
The “Accordion” sofa is famous for its dimensions when opened. They are much larger than when folded. Thanks to this, such a sofa is an excellent find for small rooms. After all, it can be placed even in the corner of the room; it is enough to ensure unhindered extension.
Sofa - accordion suitable for small rooms
Transformation mechanism for the Spartak sofa
Operating principle of the mechanism: Triple folding mechanism. You need to pull the seat of the sofa and it will unfold in three steps while standing on the extended legs.
The design of the mechanism was developed by Italian engineers. This mechanism belongs to the metal frame type. The frame is made of profile 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 sleeping place, which is especially important for tall people. The mechanism is very reliable because it does not contain wooden or plastic parts.
Advantages: reliability and durability, easy to unfold, can be used daily, flat and large sleeping place Disadvantages: there is no place to store bedding since the mechanism occupies the entire internal space of the sofa when assembled, you need to remove the sofa cushions before unfolding.
Sofa with fold-out floor
The principle of operation of the mechanism The berth consists of two sections. When folded, the sections are hidden inside the sofa body. To unfold the sofa, you need to pull up the inner edge of the sofa seat. Then, move the sections forward towards you. The sleeping place has no supports and folds directly onto the floor.
It cannot be said that the sofa is comfortable for sleeping since the joints of the sections are noticeable and the sleeping place itself is located very low. Therefore, such models can be used for occasional use as a bedroom. But for sitting it’s a completely acceptable option.
Advantages : compact dimensions when assembled, the cheapest type of folding sofas. Disadvantages : not comfortable to sleep, no places to store bedding
Roll-out sofa with drawer
In order to effectively use the living space, it is recommended to purchase a roll-out sofa bed with a drawer for linen. When folded, such furniture will not take up much space and this will save living space.
The presence of an additional drawer for linen allows you to dispense with a chest of drawers, which also helps to save free space. Often such drawers are located in the middle part of the sofa, but sometimes they can be found at the foot, which increases their volume.
There are models that are equipped with small niches in the armrests and some parts of the backrest. Such recesses can be used to store various small items, which is very convenient if your living room has a small area.
Roll-out furniture has many advantages. Perhaps the most important of them is the ability to optimize space. These products are easy to use and quickly fold and unfold. During their production, environmentally friendly and hypoallergenic materials are used.
When you unfold a high-quality roll-out sofa, you will see a full-fledged bed that does not have any depressions or bulges. Children's models are equipped with a mattress consisting of spring blocks, which allows the spine to be in the correct position during the night's rest.
Thanks to its durability and high quality, the roll-out sofa will take its rightful place in your living room. Reliable models at an affordable price can be found at.
Roll-out sofa
The principle of operation of the mechanism: The berth consists of two segments. When assembled, the segments are located in the sofa body. To unfold the sofa, you need to pull the lower part from the front. After which it will roll forward into the working position. All that remains is to fold the pillow into the free space. 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. Contains internal space for storing bedding.
Advantages: the most reliable, have a comfortable place to sleep and compact dimensions when assembled.
Disadvantages : the roll-out casters of the sofa can ruin the floor covering when unfolded, the sleeping place has a low height
Sofa "Eurobook"
“Eurobook” is also considered a popular mechanism for transforming a sofa. Its design is reliable, well thought out and easy to use. This is an advanced version of the book sofa. It is distinguished by greater comfort when opening, as well as an increased volume of the linen drawer.
Unfolding the Eurobook sofa
The very principle of opening the Eurobook sofa is extremely simple. The entire seat or part of it rests on a roller base. It is not built into the product, but stands on top. To unfold the roller part of the sofa, pull it towards you until the movement limiters operate. In this position, the space for bedding located in the base of the sofa will become visible.
Unfolding the Eurobook sofa
After the roller part was pulled out, all that remained was to install the backrest. To do this, you need to press a little on its upper part. As a result, it will fall into place, flush with the extended seat. In this position, the back will close the linen drawer, and the product itself will be completely open.

In this form, the sofa will increase in size, and now it will be comfortable for a person to lie on it. The opening mechanism is very convenient, the task can be completed without much effort.
Transformation mechanism for the Eurobook sofa
Advantages and disadvantages
The Eurobook sofa has gained popularity for a number of reasons:
- Ergonomics. It can be installed either in the center of the room or close to the wall. When opened, the sofa extends only in one direction. For this reason, it will not have to be moved away from the wall.
The Eurobook sofa is distinguished by its ergonomics
- Easy to open. The mechanism for transforming the Eurobook sofa is very well thought out. The roller base is very easy to move away.
- Linen box. When opened, a large niche is formed in the sofa. It is convenient to put bed linen and related items there.

- Reliability. The opening design and internal fittings do not require additional maintenance and can withstand heavy loads.
The only thing that can put you off buying a Eurobook sofa is the price. It will be higher than most other models. This is due to solutions in the transformation mechanism and general ergonomics.
Sofa "Puma"
Such sofas are often found in the interior of modern living rooms. When folded, they take up a small amount of space, but look quite premium. The opening mechanism is reliable. And when pulled out, parts of the sofa do not scratch the floor covering of the room, since they are not on roller bases, but on a hanging structure. The product is perfect as a place for a person to sleep. After all, it can be pulled out quite simply, while increasing its size.
Corner sofa “Puma”
Transformation of the Puma sofa
The layout mechanism of the Puma sofa is quite complex. The design consists of many individual parts. Thanks to this, when opened, the product greatly increases in size. It becomes really comfortable to sleep or lie on.
To unfold a sofa of this type, you need to raise the seat. After this has been done, you need to take out the exit bottom part. You need to pull it towards yourself until it stops. Now you can pull out the seat of the exit part. There are special loops located on the sides of the center for this purpose. You must first pull them up and then back until the limiters operate. To complete the transformation, all that remains is to lower the main seat block, which was raised from the very beginning, into place.
Puma sofa transformation mechanism
After these operations, the Puma sofa was finally unfolded. After opening, the seat area will increase several times. Now it can be used for its intended purpose, that is, lying down.
After transformation, the puma sofa increases significantly in size
Sofa features
The Puma sofa is compact when folded. It can be placed in places with a small amount of free space. For example, against a wall or in a corner of a small room. And when opened, it increases significantly. Therefore, nothing should stand in its way, because it will interfere with its movement.
The puma sofa when folded is quite compact
Most modifications of the Puma sofa do not have a drawer for linen. It is only available in corner models. This is the main drawback of a product with such a layout mechanism. Plus, the sofa belongs to the high price segment.
Mechanism for folding out the sofa “Conrad” (“Telescope”)
How the mechanism works : “Conrad” 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 another. Because of this feature, the mechanism was nicknamed “Telescope.” The sections roll out and stand on supports.
"Conrad" is a subtype of a roll-out sofa. The fundamental difference is the greater height of the berth.
Advantages: reliable mechanism suitable for daily use, sofas have a compact volume, are equipped with a drawer for linen, comfortable for sleeping
Disadvantages: the mechanism and sofa are heavy
Transformation mechanism for the “Dolphin” sofa
How the mechanism works: To unfold the sofa, you need to pull the front part of the sofa from below. As a result, a section hidden inside the sofa body will roll out towards you. Inside the roll-out section there is a pillow with a strap. You need to grab the strap and pull the pillow up. It will “emerge” and stand on the same level as the sofa seat cushion. Voila, the sleeping place is ready.
The Dolphin mechanism is mainly used in the designs of corner sofas. Bed storage space is not located in the roll-out part of the corner sofa. The mechanism puts a significant load on the body of the sofa, so when purchasing, pay attention to the material of the body. Knots are not allowed if wood is used.
Advantages : comfortable sleeping place, ease of use
Disadvantages : not very reliable mechanism, service life is about 7 years.
Sofa "Dolphin"
The list of popular sofa transformation mechanisms includes the “Dolphin” modification. It is included in it because of its convenience, ease of opening and small size. The sofa itself is divided into two parts. One of them occupies a large area and is static. But the second one is retractable. It is located under the seat of the sofa. Because of this, its dimensions are not very large. Typically, Dolphin designs are installed in corner sofas.
Dolphin sofa
How the Dolphin sofa opens up
The folding mechanism of the “Dolphin” sofa is lever type. Therefore, it is revealed extremely simply. It is enough to pull the retractable part towards you until the limiters operate. When opened, the mattress block will be visible inside. It needs to be pulled out from there, placing it on top of the sliding part. Usually, special hinges are provided in the sofa for this purpose.
Transformation mechanism for the “dolphin” sofa
When opened, the product increases slightly. This is due to the overall compactness of the transformation mechanism.
Peculiarities
The popularity of the folding mechanism in Dolphin-type sofas is primarily due to convenience. To open it, just pull the bottom part. The process itself takes minimal time and requires almost no effort. Also, such sofas have a large drawer for storing bed linen.
Linen box in the dolphin sofa
The disadvantages include not the lowest price of the product. Basically, Dolphin sofas are corner sofas, so they are quite expensive. Also, the movable structure, when opened, is under constant load. In this regard, internal fittings require additional care and regular lubrication. Otherwise it won't last long enough.
Corner sofa “dolphin”
The fact that when opened, the “Dolphin” sofa does not take up very much space can hardly be attributed to advantages or disadvantages. Because of this, the product cannot always become a full-fledged sleeping place for a person. However, such a sofa can be placed in a place with insufficient free space. And this is a very ergonomic solution.
Transformation mechanism for the Kangaroo sofa
The principle of operation of the mechanism: completely similar to the operation of the Dolphin mechanism
The Kangaroo is a variation of the Dolphin mechanism. Due to its design, “Kangaroo” allows you to make sofa models with high legs, which increases the height of the berth. The mechanism received its name for the similarity of the trajectory of unfolding a sofa with the trajectory of a kangaroo jump.
Advantages : ease of unfolding, optimal sleeping height.
Disadvantages : not durable.
Transformation mechanism for the Elf sofa
How the mechanism works: The mechanism unfolds simply. The armrests are moved to the sides to create a sleeping area.
“Elf” refers to metal-frame mechanisms. The frame is made of metal profiled pipes. Wooden slats. The armrests are height adjustable and have several positions. This feature allows you to create the most comfortable position of the armrests for a reclining position.
Advantages: compact model of sofas, good flat sleeping place, slats give a good orthopedic effect, armrests are adjustable - you can create a sofa for yourself.
Disadvantages: you cannot place the sofa close to the wall; the sleeping area is located in the same place as the seating area.
Transformation mechanism for the “Recliner” sofa
“Recliner” got its name from the English word recline - to recline or lean back
The principle of operation of the mechanism: The transformation of the sofa is controlled using complex mechanisms hidden in the body of the sofa. With their help, you can adjust the tilt of the sofa back and extend the footrest to a given distance and at a certain angle.
Some models have vibrating 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 are capable of adjusting and remembering the mechanism settings made directly to your body.
Advantages: very easy to use, have fine settings - you can create a sofa just for you.
Disadvantages: high price, used only as a place to relax since there is no place to sleep
General conclusions
- Pay close attention to the mechanism when buying a sofa. The ease of use and service life of the sofa will depend on choosing the right mechanism.
- Match your needs with its capabilities. How often will you unfold the sofa, what space do you have allocated for installing the sofa, especially when unfolded.
- Don’t choose a sofa with a mechanism that is obviously not suitable just because the color is cool or because your neighbors have one. Choose individually for your needs.
