Corner sofas with mechanism "Accordion"

Corner sofas with the mechanism "accordion" - is a modern upholstered furniture, which is very popular among buyers. The demand for the design is explained by a number of functions and qualitative characteristics.

The name of the mechanism "accordion" speaks for itself. The sofa is transformed according to the principle of an accordion: it is simply stretched, like the furs of an instrument. To expand the sofa, you just need to pull the seat handle. In this case, the back, consisting of two identical blocks, will drop itself. In the unfolded form, the bed will consist of three blocks of the same width and length.

The difference in angular design is the presence of an angle. Today, manufacturers produce models with a universal angular module, which can be changed in any direction. This is convenient and allows you to adapt to the particular room. The sofa can be put in the bedroom, where it will replace the bed, be placed in the living room (then it will determine the seating and reception area). If the floor space allows, a model with an accordion mechanism can be put even in the kitchen.

The advantages of such structures are many. Accordion sofas:

• mobile and not difficult to rearrange furniture;
• due to the reliable mechanism of transformation practical in operation;
• have a different degree of rigidity of the blocks;
• happen with preventive, and also with massage effect;
• differ in a wide model range and various functions;
• have a modular design system;
• suitable for adults and children;
• are an alternative to a full bed;
• with proper selection of the block, they contribute to the most comfortable and proper rest;
• differ in the sizes and height of a berth;
• have an easy-to-work transformation mechanism that even a teenager can do;
• made with different upholstery materials, so you can buy a model in the color and design you like;
• They differ in cost - depending on the filler, body and upholstery.

The disadvantages of the corner models with the accordion design include the load on the body when the mechanism is operating.

Corner models with the mechanism of "accordion" are different. They differ from each other in design, size and feature set. They are of three types (depending on the destination):

• soft;
• moderately tough;
• tough.

The first type is considered unreliable, it does not provide a full rest during sleep. The most popular options are medium hardness. They are bought more often, as they can withstand an average weight of one, two or even three people, serve about 10-12 years.

Models are also varied externally: there is a box for linen, corner sofas can be without or with armrests, with compartments located in the armrests, with additional corner tables or a bar.

Accordion designs are made in different styles (modern, classic, minimalism, neo-baroque, art deco), so they successfully complement the existing interior of the room.

The modular principle of the corner sofa is very convenient, because such furniture is not only mobile, but also multifunctional: the corner unit is often used as a chair in which you can store bed linen or other things. The main part with a box for linen unfolds, forming a smooth sleeping bed, like a bed, and the wide sides in some models can be used as tea tables.

In the production of corner sofas with the “accordion” system, companies use steel, wood, plywood, synthetic and natural fillers, and various upholstery materials.

Such designs are performed on the metal frame, this explains the reliability of such sofas.For the base often used lattice lamellae (elastic wooden products that prevent the block from bending). Plywood - a budget version of the base, however, and the most short-lived.

The block of such a sofa can be of two types: springless or on springs. In each of the categories there are good options that provide not only comfort during sleep, but also the correct position of the body - without curvature of the spine.

Such a block is made of natural or artificial latex, furniture foam rubber of two types (T and HR), struttofiber and is supplemented with coir (coconut fiber), less often with felt and padding polyester (and in decorative pillows it is holofiber and synthepooh).

The best varieties of such a mat are recognized as PU foam type HR and latex block. They are resistant to high weight loads, do not creak and do not deform. Polyurethane foam is somewhat inferior to latex, it costs less, but in itself it is rather elastic.

In addition, a great variation of the block is combined, when hard coconut fiber is added to the top and bottom of the filler. This mat has an orthopedic effect, it saves from back pain, but it is not designed for people with excess weight, as it can break.

The spring block is divided into dependent and independent types. The first springs are connected to each other, the second work separately.

In total there are three types of spring block:

• snake;
• bonnel;
• independent type (with "pockets").

Snake (or serpentine springs) are less practical and stretch faster than others. Such springs are located horizontally, they are the base of the sofa.

Bonnel consists of twisted springs, arranged vertically, interconnected with the grid frame. So that the block does not hit the body, the top, bottom and side edges are supplemented with furniture foam.

Independent springs arranged vertically. They are distinguished by the fact that each of them is dressed in an individual textile case, so the steel elements do not touch each other. The integrity of the grid unit is ensured by connecting tissue covers.

Corner models with the accordion system are made of the same materials as the entire line of upholstered furniture. The most popular upholstery options remain natural and eco-leather, leatherette:

• Leather sofa practical, such upholstery is easy to wipe, it is resistant to mechanical damage. In addition, the texture is different (it can be smooth, with a print and a relief).

• Leatherette less practical, since the layer-skin with intensive use is quickly separated from the fabric base. In this case, you need to protect furniture from dirt and moisture.

• Textile group Upholstery includes materials such as flock, velor, furniture tapestry and jacquard. Fabric upholstery is very bright, can be printed and has a rich color palette. It is easy to pick up such sofas to already available furniture. The disadvantage of textile upholstery is the collection of dust, dirt and moisture. It is impractical to use, as it forms scratches, cuts and abrasions faster than other materials.

The size of the corner sofa can be different. This is due to the fact that each manufacturer sets its own standards. On average a berth can be about 2 × 2 m, its height is 48-50 cm.

Depth varies from 1.6 m to 2 and more. Some models are very spacious, they can reach a length of 2.4 m.A large sofa allows you to place on it not only two, but also three people. This is especially true if you need to arrange guests.

It is necessary that the depth of the bed was at least 20-30 cm more than the height, otherwise you will not be able to relax on such furniture. Width is equally important, even if you purchase a small sofa. At least 20 cm on each side should be.

Corner sofas with the mechanism of "accordion" are considered good furniture. This is evidenced by the numerous reviews left on the Internet. The design mechanism is very convenient, easy and safe in transformation. The comments indicate that such sofas significantly save the usable area of ​​any room, conveniently located in the corner.

Opinions are ambiguous about the sofa block. Some prefer the spring, talking about the durability of such structures, others choose models with springless unit and orthopedic effect, which do not creak and have a long service life - up to 15 years.

Good models include Karina, Baron, Denver, Samurai, Dallas, Venice, Cardinal. These are very popular corner options made on a metal frame and having an elastic and flexible polyurethane foam block. These designs are chosen for their reliability, quality, unique design and long service life.
