American folding sofa: advantages and disadvantages

Good day to all! When choosing upholstered furniture, you should always think about comfort, safety and healthy sleep on it, if it is intended for regular use. The American folding sofa is popular in our country and beyond.

This is a fairly universal design, which in everyday life is used as a regular sofa, and at night turns into a comfortable sleeping place. Moreover, visually even narrow models turn out to be spacious and roomy.

What interests us most about such folding sofas is the transformation mechanism. I propose to learn about its features, look at the varieties, and also study the list of advantages and disadvantages of such furniture. And if you have an American folding bed, leave reviews and share your personal impressions of its use.

Relax

The original mechanism for folding the seats ensures synchronous advancement of the seat and the front wall when reclining the backrest. As a result, the front wall becomes an additional retractable stand on which you can comfortably place your feet. The chair can automatically adjust to the person, providing comfortable seating and ergonomic posture. Correct posture promotes relaxation, reduced pressure in the knee joints, and even distribution of the load on the cervical vertebrae.

Advantages:

Formation of correct ergonomic posture when sitting;
Ease of transformation;
Reliability and strength of the structure.

Flaws:

The need for location away from the wall.

Varieties

American folding sofas have 2 options for a transformation or folding mechanism. Moreover, one is already outdated. The second type is an excellent replacement for an almost retired mechanism.

The first type requires removing the upper part, which acts as a seat. You can make a sleeping place out of a sofa by pulling the special handle up and then towards you. The folding bed unfolds and can be used for sleeping. The mechanism is outdated;
The second option is called sedaflex. The seat here cannot be removed, it is fixed to the base of the berth. When the sofa is folded out, the pillow ends up under the bed. It is not used for sleeping, which allows for a longer service life. Sedaflex features a folding mattress, headboard and durable frame.

If we take the design as a basis, then folding beds can be divided into angular and straight.

Straight ones will be a good choice when organizing a children's room and even an adult bedroom. Corner ones are used in living rooms, since such models are distinguished by their substantial dimensions, requiring more space for unfolding.

Before you buy an American folding bed, be sure to take a look at what the mattress itself is placed on and what base it will be on.

Since you will probably buy a sofa with the sedaflex system, you will have several options. This is an awning, lattice or armor. I strongly recommend taking furniture from only one of the last 2 types of base. The battens and lattice ensure high-quality installation of the mattress, which will not sag under the user’s weight. If the base is made in the form of an awning, you cannot count on a long and comfortable sleep in this case. The mattress will sag and your back will probably start to hurt soon. Such a sofa is harmful for the spine.

Well, the mattress itself can be orthopedic and regular. If you wish, you can make a foam mattress yourself, but here I advise you to take furniture exclusively with an orthopedic product.

What it is

A folding sofa is a type of upholstered furniture with a double-folding mechanism. If you unfold the structure, you get an impressive-sized sleeping place, which is located perpendicular to the backrest. A pair of sections are connected using hinges.

Varieties

The range of products in the furniture industry is huge. Orthopedic sofas provide healthy, sound sleep and fit well into the interior. To make your choice easier, experts regularly rank the best sofas for sleeping, which are the simplest and most comfortable for daily use. The following products are most popular among consumers: Askona Sunrise, Askona Sunset, Andersen Benedict, MOON-021, Andersen Winter Dream. These manufacturers boast the best sofas for sleeping. Their products satisfy the need for complete relaxation after a busy day. A restful, long night's sleep will be a confirmation of the quality of the product.

By shape

The size of the room in which the sofa will be installed and its design influence the choice of the shape of the product. Depending on the characteristics of the room or interior design style, furniture can have different configurations:

Direct model. It is a single plane, usually installed along the walls in large and medium-sized apartments. It has a deep, comfortable seat and is often used as a sleeping place.
Corner design. It will fit well into a small room. The seat is not soft, and not all models have a drawer for linen.

Availability of free space is not the only criterion when choosing the shape of a product. Often corner sofas for sleeping are used to zone an apartment. An original design solution sometimes makes it the main element of the interior.

Angular

By folding mechanism

Modern people value multifunctional things that can satisfy a number of needs at once. Thanks to the transformation mechanism, it is easy to get a comfortable sofa for daily sleep or a comfortable seat. The following varieties are very popular:

Click-clack. In order to get a wide sofa for sleeping, you need to raise the lower section to a vertical position (you will hear a clicking sound), and then lower it to its original place. There should be a small space between the wall and the folded product for free lowering of the second half.
Eurobook. The front half moves forward, and the resulting space is filled by the back. The sofa can be transformed into a sleeping place, being in close proximity to the wall.
Accordion. It is enough to pull the lower section of the seat towards you, the part lying on it will lower with the backrest into the free space.
Dolphin. It is necessary to extend the lower section of the seat, in which the additional mattress block is placed. By pulling the rings specially built into it, you can place the block on the same level as the rest of the soft parts.
French folding bed. An additional element of the orthopedic lattice folded in half is located under the seat. If necessary, it rises, moving forward by 1.5-1.8 meters.

When choosing a sofa transformation mechanism suitable for frequent use, you should take into account priorities. A wide and flat sleeping place, for example, will be provided mainly by a click-clack or an accordion. In small apartments, compact and functional furniture is valued. Experts believe that the most reliable mechanism for transforming a sofa is a simple and durable click-clack.

To size

Furniture stores offer sofas for daily use, taking into account the age and individual characteristics of consumers. The size of a single product is 130-170 x 90-100 cm, a version designed for two people is 170-200 x 100-140 cm. A sofa for sleeping in a small apartment often has built-in shelves and wide armrests. Such models can be installed in the kitchen or office. The corner sofa in the living room for daily sleep can be four or five seats. Its dimensions reach up to 400 cm, width – up to 220 cm. Bright children's models are often made in the form of a chair with soft armrests. Standard dimensions: 95 x 100 x 85 cm.

Depending on the shape, you can choose a straight or corner sofa.

The direct modification is compact, ideal for small spaces: bedrooms, children's rooms.
The corner design has an original look, is equipped with a linen box, and will provide seating for a large company. The location of the additional module can be chosen at your discretion (left- or right-hand). Such products look good in the living room or studio apartment. The model can be habitually installed in a corner or used to zone a space.

The dimensions of the sofas are presented in the following figures:

length 190-230 cm;
depth 93-115 cm;
height 75—

Bed parameters:

length 188-196 cm;
width 75-140 cm;
height above floor level 45-50 cm.

Book transformation mechanism (click-clack)

A book sofa is one of the most common types of budget sofas. For transformation, the seat in these models is raised to characteristic clicks and lowered along with the backrest. The same actions are carried out when folding.

The click-clack mechanism is a more modern modernization of the book system. Modernization has introduced an intermediate position into the functionality of the sofa - half-sitting (relaxation). Such models are very practical (they have removable covers and drawers for linen), and even when unfolded they do not take up much space in the room.

Scheme of transformation of a sofa book, advantages and disadvantages:


Advantages of the design	Design flaws
Modern book sofas have a “relaxation zone” function - when the back is reclined at an angle, thanks to which you can take a reclining position on the sofa. The mechanism is very durable. There is a fairly spacious laundry compartment.	The width of the bed may seem insufficient to some. When transforming the sofa into a sleeping position, it must be moved away from the wall. When reassembling, the sofa moves closer to the wall. Over time, a bump, dent or gap may appear at the junction of the seat and backrest.

Sofa with American folding bed mechanism: features and advantages

The American folding sofa (geographically more accurate would be the term “Belgian bed” or “Belgian folding bed,” which is much less common) is equipped with a sedavlex mechanism developed by the Franco-Belgian concern SEDAC-MERAL.

Most models provide the ability to unfold the sofa without removing the pillows from it - they are fastened (secured with belts), so when transforming the sofa, they are wrapped under the mattress, as if “hanging” under it.

The frame is made of metal, to which bent-glued orthopedic armor is firmly attached. Initially, the base was made of a mesh (with small/large cells), but due to the sagging of the mesh, this option was completely abandoned. In the latest models of the Sedaflex mechanism, a combined base is used - in the central and head parts - a more comfortable plate base, and elastic straps are installed in the legs.

The mattress for American folding mechanisms is quite thick - there are options with a thickness of 10, 12 or 14 cm and of various types - both spring and polyurethane foam. Recently, multilayer models are more often installed, in which a spring block is located on the bottom and a soft layer of filler on top.

The basis of the mechanism is an American clamshell

Transformation of the American folding bed mechanism

An American folding sofa is usually equipped with a lightweight mattress that has a minimum of padding, in most cases one-sided (that is, the mattress has only one side to lie on).

To prevent back disease, they produce an orthopedic American folding sofa bed with a specialized mattress.

Other advantages we note:

ease of transformation - folding out the sofa does not require excessive effort
Quite compact when folded

ability to withstand significant (standard - up to 200 kg, but there are models with reinforced armor that can withstand loads of up to 250 kg) weight of vacationers

a sofa with such a mechanism can be installed on any floor covering without restrictions. When unfolding there is no risk that the parquet (laminate) may be scratched. Unlike roll-out models, the American folding sofa can be installed on a carpet (carpet) - if regularly unfolded, there will be no marks or dents on it

the base of the sofa is a mechanism that has its own frame, and the remaining elements of the sofa are attached to it - the sides, back, drawer. Thanks to this, the sofa can be brought into the apartment in parts and assembled directly inside. And you don’t have to look for a large truck to transport it

a seamless mattress, as well as the stability and rigidity of the structure, guaranteeing the absence of squeaks - all this will ensure a comfortable and restful sleep

large model range - the ability to choose a sofa in almost any style, from classic to hi-tech

Leather upholstery has many advantages

One of the main disadvantages of the American folding sofa bed is the lack of a linen drawer. However, this drawback can be easily compensated for - today you can find a corner version of a sofa of this type, where an additional section, made in the form of an ottoman, is equipped with a lifting mechanism, and its internal volume is sufficient for storing linen. Another rather significant drawback is the deep installation location: a distance of about 1-1.1 m will be required from the edge of the seat to the wall.

First in orthopedics

A sofa is a piece of furniture that has a place in every home. The sofa is an invariable part of the interior of the living room of a city apartment, a private mansion and a country cottage. Very often it performs another important function, providing additional sleeping space in the house. Modern manufacturers offer this type of furniture such as an American folding sofa, which can replace a full-fledged bed. This is a very comfortable sleeping place, often equipped with an orthopedic mattress, reliable and durable.

The design of such a sofa includes a mattress, which is located directly under the seat, not being part of it. To remove and unfold such a mattress, you need to first pull it up, then towards you. When folded, the American folding bed looks like an ordinary sofa. However, its main feature is the ability to turn into a wide and comfortable sleeping place in a matter of minutes.

To make unfolding the mechanism convenient, it was equipped with a metal handle. As soon as the mattress is pulled out, it is immediately automatically fixed with a reliable support. The entire structure is highly durable and reliable, so during sleep there is no fear that the mechanism will fold and the sleeping person will end up on the floor.

An American folding sofa is made in the form of a traditional or corner sofa. Thanks to this design, you can place a sleeping place in any part of the room. Such sofas come with or without armrests.

According to the type of design, American folding sofas are:

Straight - these are most often used in bedrooms and children's rooms;
Corner - as a rule, such models are installed in living rooms; they have substantial dimensions and are not suitable for small rooms.

As for the orthopedic mattress, it is installed on the following types of surfaces:

on the grill;
on the grid;
on armor;
on the awning.

The most durable are sofas equipped with bars or armor. In addition, such designs provide the mattress with increased rigidity. It is recommended for people with a lot of weight to choose a sofa of this design.

Before laying out a sofa with an American folding bed mechanism, you should remove pillows and other objects from its surface. After this, you need to take the metal handle located under the seat and pull it towards you. At this point, you need to support the retractable system with your free hand, making sure that it rises smoothly.

After the mechanism is completely outside, it must be fixed by extending the support leg. This sofa is highly reliable; the leg provides good stability and fixation of the structure. The entire process of unfolding the sofa takes no more than a minute, and even a child can cope with such a task.

It is recommended to choose a folding sofa if there is a need to equip additional sleeping places in the house. It can also easily replace a regular children's bed. However, you should not constantly use a sofa instead of a bed in the bedroom of two adults - under such weight, the mechanism will eventually begin to sag, creak and become deformed. Still, the American folding sofa is intended for periodic use as an additional, and not the main, sleeping place.

The enormous popularity of the American folding sofa is due to a number of factors. Its advantages are as follows:

Thanks to the massive base, the design is reliable; when unfolded, it is stable and does not move to the side.
The sofa transformation mechanism is made of lightweight, yet durable material.
This sofa is a multifunctional item that can last for a long time.
Thanks to the wide sleeping area, the model provides maximum comfort while sleeping.
When not disassembled, such a model is a comfortable and stylish sofa that can fit perfectly into any interior.
Thanks to the orthopedic mattress, even people with spinal diseases can sleep on such a sofa.
A sofa with an “American folding bed” mechanism can withstand a weight of up to 200 kg; if necessary, the structure can be reinforced with armor.
A model of any size can be brought into the apartment disassembled and assembled on site without much effort.
Thanks to the huge range of models, it will not be difficult to choose a folding sofa that will match the overall style of the room.
The cost of such a sofa cannot be called high; it is quite affordable for the average family.

Despite a number of advantages, the American folding sofa also has some disadvantages:

This sofa has quite massive dimensions, so it is not suitable for installation in small rooms.
After prolonged use, the structure, equipped with springs, begins to creak, causing discomfort to the owners.
The folding sofa is not equipped with linen drawers, since all its “insides” are occupied by a folding mechanism with a mattress.

When choosing an American folding sofa, you should pay attention to the following parameters:

Dimensions of the model - if the room is small, you should choose a compact sofa.
Availability of space in the room sufficient to transform the sofa - in cramped rooms filled with furniture, it will not be possible to expand such a model.
The purpose of the room itself is that for the living room you should choose corner or straight models with a large number of seats. A modular design is more suitable for installation in a children's room or bedroom.
Interior style of the room - the sofa should be harmoniously combined with all the interior details.
The purpose of the sofa is that if it is installed in a children's room, then preference should be given to a springless model, which is more suitable for the child's spine.
Characteristics of the upholstery - it must be sufficiently strong and wear-resistant.

If you choose the right American sofa, it will serve its owners for many years without losing either its external characteristics or functionality.

Professional furniture makers advise cleaning the surface of the sofa from dust, pet hair, crumbs, and other small debris approximately once every three days - this can be done with a vacuum cleaner or a regular brush. Thus, the upholstery will remain clean, maintaining wear resistance and strength for a long time.

If complex stains appear on the surface of the folding sofa, they must be removed using products designed specifically for this type of fabric. General recommendations for caring for your sofa:

Cleaning movements should be carried out in the direction of the pile of the upholstery fabric.
If liquid is spilled on the surface of the folding sofa, it should be blotted rather than wiped off.
It is not recommended to use aggressive cleaners containing acids when caring for your sofa.
If the sofa has been wet cleaned, it can only be used after it has completely dried.
If the mechanical parts of the structure break down, they can be replaced with new ones and the operation of the American folding sofa can continue.

Sedaflex

Reliability and ease of folding allow us to classify the Sedaflex mechanism as one of the most popular folding systems. The mechanism is designed for intensive use - sofa beds with the Sedaflex system can be used daily. The transformation system is a double-folding system; to change the configuration of the sofa, you need to pull it up and towards you, then unfold the sections and unfold the legs. The folded mechanism does not affect the dimensions of the product or the design of the furniture. The strength and rigidity of the frame is ensured by the use of steel pipes with two transverse elements. The absence of wooden or plastic elements in the design ensures a long service life of the system and the possibility of daily use.

Advantages:

Simplicity and convenience of folding;
Spacious sleeping bed;
Orthopedic base with armor.

Flaws:

Lack of storage system for linen;
Limitation on maximum loads.

Detailed description of the Sedaflex mechanism

Types of fillers

The peculiarity of Sedaflex mechanisms is that they can be equipped with mattresses 10-14 cm high.

The following options are available as filler:

polyurethane foam;
latforms;
natural latex.

Let's look at the pros and cons of each to understand which is better for daily sleep.

Polyurethane foam with a density of 25 kg/m3 is used in budget models. It has good elasticity, is safe for humans, and is designed for a 10-year service life. There is polyurethane foam with a wavy surface, which provides a massage effect.

Latform or artificial latex is an innovative material with unique characteristics:

high elasticity;
quick recovery of shape;
low level of deformation;
durability (up to 20 years without loss of properties);
environmental Safety;
ability for thermoregulation and natural ventilation.

Natural latex is considered the most expensive filler. It evenly distributes the load, ensures the correct position of the spine, does not cause allergies, is permeable to air, and will last at least 20 years.

The monolithic block of filler is enclosed in a cover made of quilted jersey or jacquard.

Multilayer mattresses come in spring and springless types.

The first group includes the Bonel system. The composition also contains felt and foam rubber. The spiral elements are connected into a single whole, therefore they are not able to react pointwise to the load, the contacting metal parts make an unpleasant sound, and over time, dents form on the mattress. This option is not suitable for daily use.

Springless mattresses combine materials of different hardness, which allows you to create comfortable sleeping conditions.

For example:

a layer of struttofiber between two blocks of polyurethane foam will give the product additional softness and elasticity;
a small layer of latex on top of polyurethane foam enhances the orthopedic properties.

By following simple steps you can extend the life of your mattress. It is enough to turn the product over once every 3 months, changing sides.

Tips for selection and operation

When choosing a sofa with a folding bed transformation mechanism, you need to start from the purpose for which and in what room this model is being purchased. If you plan to sleep on it every day, then you should purchase the “American” or “Italian” options. Purchasing “French” is allowed only on a base made in the form of a welded mesh. The first two varieties are already equipped with a thick, comfortable mattress, and the third can be used with a double orthopedic mattress up to 18 cm thick.

As a guest option, the “French” model, equipped with a lightweight tent or tent-batten clamshell mechanism, is quite suitable.

Another important selection criterion is the load-carrying capacity of the sofa. Here it should be taken into account that the “American” and “Italian” versions, as well as the “French” models equipped with a base in the form of a welded mesh, can withstand a weight load of 200 kg

You should also take into account the height of the person who will use the sofa as a place to sleep: if his height exceeds 185 cm, then you should only purchase an “Italian folding bed”

Sedaflex sofa design

This folding soft couch is a two-fold transformation mechanism, the purpose of which is to constantly use it for relaxation and sleep. The basis of the transformer is a metal frame to which bent-glued armor is attached. Fastening occurs using plastic brackets. In some models, the base for the bed is a metal mesh with cells of various sizes, which is attached around the perimeter to the frame with springs, plastic brackets or electric welding. There are also samples where the sleeping base is combined: it consists of bent-glued armor and elastic belts at the foot of the bed.

Sedaflex folding couches 100% replace stationary traditional beds, being at the same time a bed, a place to relax and spacious storage for things. The cost of this transformer is relatively low, which sets it apart from furniture of a similar class and attracts those who want to furnish their home.

What is

A sofa with a French folding bed mechanism is one of the most common and popular models of transformable upholstered furniture. The origin of the name is due to the location of the very first manufacturer of three-section folding systems - it was founded in France. The popularity of the design is explained by its compactness, ease of use, relatively affordable price, and various design options for this furniture.

The transformation mechanism consists of three sections connected to each other by a hinged fastening. The folding of the sofa is carried out in two stages, as a result of which these elements form a single plane. The service life of the product, the thickness of the mattress, and the comfort of people resting on this structure depend on the type of base.

The following is used as a support under the mattress of a French folding sofa:

A metal frame, inside of which a durable synthetic awning is fixed, or, as an option, wire mesh. The tent structure is reminiscent of Soviet-made cots. The wire mesh base is similar to the armored (spring) beds of the same era. Both options have one significant drawback: over time, the surface loses its elasticity, making it impossible to stay comfortably on the sofa. Such supports cannot withstand a load of more than 90 kg, even for short-term use. Despite the most affordable prices among possible modifications, now sofas with this type of base are practically not produced.
Lamels (armor). The mattress is supported by bent-glued wooden slats. The battens are made with a certain bend directed towards the mattress to compensate for the weight of the sleeper. The material used is inexpensive hardwood (beech, birch), glued into a curved strip 12-15 mm thick. In some designs, an awning covering is pulled over the battens to more evenly distribute the load and also reduce sagging of the mattress. Bases with more than 10 lamellas are considered orthopedic and can withstand weights of over 150 kg. The structures belong to the middle price category, mainly intended for guest use - it is in this mode that they will last longer.
Spot-soldered lattice. A reliable and durable solution, which, despite its high cost, is in demand among consumers. A metal mesh attached to springs does not stretch under a person’s weight, making it possible to create a permanent sleeping place with an orthopedic mattress, increasing the load on the structure to 200 kg. A French folding sofa with a base made of welded metal mesh is the only option suitable for everyday use as a sleeping place.

Roll-out mechanisms.

IMPORTANT! Pay attention to the rollers and supports on “roll-out” sofas. They must be made of soft materials - this will ensure the safety of your floor!

"Eurobook"

- This is an improved version of the “book” mechanism. It is worth saying that this is one of the most popular vacant mechanisms on the market. The model consists of two parts: a back and a seat, and also has a spacious box for linen. To unfold the sofa, you need to remove the back cushions, roll the seat towards you all the way, and lower the backrest into the free space. All parts of a sofa with such a mechanism must fit tightly to each other, but if gaps appear in the sofa, this indicates low quality of the product. Maximum load is 240 kg.

Pros:

such a sofa looks good both against the wall and in the middle of the room (it can be used to zone a room if space allows).
"Eurobook" provides a full-fledged spacious sleeping place. Cons:
when extended, the seat “rides” on the floor and can damage the floor covering.

"Dolphin"

- perhaps one of the most convenient and widespread mechanisms on the market. It unfolds very simply: just roll out the additional section from under the seat and pull the fabric handle towards you - the sofa is ready for use. The maximum load on the mechanism is 200 kg.

Pros:

Robust design guarantees longevity of the mechanism.
The sofa provides a spacious sleeping area, and there is a spacious linen drawer. Cons:
When unfolded, there is a barely noticeable joint between the seat and the roll-out section.

"Kangaroo". This mechanism is very similar to the previous one in terms of folding. Its only difference from the “dolphin” is its higher sleeping place.

Pros:

durable construction, wide berth, large linen drawer.
Cons:
when unfolded, there is a joint between the seat and the roll-out section.

"Conrad" (telescope).

This mechanism consists of three sections. To unfold, you need to pull the lower roll-out part (the first section), behind which all the others will pull out. After you have pulled out all the sections, you need to take the top of the first section and unfold it to lay it on top of the second. IMPORTANT! The “telescope” is very compact compared to other mechanisms, and also has an orthopedic grille. The maximum load on the bed is 180 kg.

Pros:

compactness when folded and space when unfolded.
Cons:
difficult to move - the mechanism and the sofa are heavy.

Advantages

The American folding sofa has many attractive qualities for the buyer, here are some of them:

A massive metal frame that prevents the bed from moving and gives a feeling of reliability and stability.
The couch has a simple, intuitive transformation device, and the folding arms are made of durable light metal alloy.
A large-sized sleeping bed that promotes comfortable sleep.
The possibility of using the couch for relaxation not only in disassembled form, but also in assembled form, which is ensured by wide comfortable seats.
The design of the transformer is durable and can withstand significant loads (200 – 250 kilograms). Does not lose its qualities over many years of use (if the operating rules are followed, the product can last ten years or more).
Most American folding sofa beds are sold with an orthopedic mattress, which allows you to rest comfortably even for those suffering from insomnia and musculoskeletal diseases.
The ability to lift the transformer up stairs or bring it into a room with a small doorway in parts with subsequent assembly.

To the numerous advantages of Sedaflex, we must also add the fact that the folding sofa does not damage the floor covering; after its use, there are no dents or scratches left on the floor. The universal design allows you to look stylish in the overall furniture ensemble of the apartment.

Brief historical background on origin

This type of folding upholstered furniture is attributed to “American citizenship,” although these interior items are indirectly related to the United States of America. In fact, this transformer was developed by engineers from the furniture company Sedac from Belgium, which was later merged with a company of a similar profile from France - Meral. And this folding sofa became “American”, apparently, due to the fact that the model was initially developed exclusively for the US market.

After sales turned out to be very successful, the management of Sedac-Meral decided to expand the geography of supplies. As a result, this upholstered furniture has become popular all over the world. In the post-Soviet space, such a transformer is also known as a Sedaflex sofa, which is a distortion of the name of the developer company Sedac.
