The mechanism of "Sedaflex": description, advantages and disadvantages

Practically in any modern sofa there is a mechanism that allows you to transform it from a place to sit in a full sleeper. In small apartments, where the area of rooms sometimes does not exceed 15 square meters, the folding sofa is the solution to the problem of inadequate living space.

The most popular devices for transformation are "Eurobook", "Dolphin", "Accordion" and "Sedaflex" mechanism. Reviews about the French clamshell (this is how the people are called "Sedaflex") have mostly positive characteristics: users find this option the most suitable for small apartments, besides it is convenient to use and relatively inexpensive.

Description

The mechanism of transformation "Sedaflex" appeared in the early 90's and immediately gained popularity. Earlier, soft furniture manufacturers used a withdrawable mechanism, which could form up to 3 cm of difference between the parts of the structure. Talk about a comfortable dream in such conditions is not necessary.

The developers of this mechanism was the Belgian company Sedac, whose name formed the basis for the name of the device.

The mechanism of Sedaflex produced a qualitative revolution in the furniture industry: the sleeping place acquired a more stable and comfortable base in the form of a spring mattress, it was easy to pull out without requiring a preliminary unfastening of the pillows. When the structure was unfolded, they were transformed into a part of a bed or hidden in special niches.

The structure of the mechanism is made of reinforced steel pipe 3 cm in diameter, and the sleeper is secured with elastic straps.

The principle of action: the mechanism of double addition, which is decomposed forward, perpendicular to the base. It is operated by hand, it is enough to pull it slightly upwards and to itself, unfolding the components of the sleeper. They rely on steel legs of increased stability.

Comparative characteristics

The American clamshell is often confused with the French. The principle of operation of these mechanisms is really similar, but there are also fundamental differences.

The mechanism of transformation "Sedaflex", as a rule, is completed with a quality thick mattress (from 10 to 14 cm) and is decomposed into two, rather than into three parts.

Since the number of joints directly affects the level of comfort, it can be said with certainty that sleeping on a two-part "American" will be much more comfortable than on a three-part "Frenchwoman".

Another significant difference is the size of the berth. The mechanism "Sedaflex" is equipped with mattresses, which are suitable for almost any height (height 195 cm), they can be used as a double bed (width up to 153 cm). For a French clamshell, a length of not more than 185 cm is available, and a width of up to 145 cm. If you subtract indents from the length parameter for placement of the pillow (about 50 cm), then you can conclude that an adult male with a height above the middle will hang his legs, which is not Too much comfortable.

The mechanism of "Sedaflex" is prepared for everyday transformations and high loads, and, therefore, is more acceptable for everyday sleep than a French clamshell.

However, he has a worthy competitor - the folding mechanism of the Tornado. Despite the higher cost, it has a number of interesting advantages:

- the maximum size of a berth 190 * 160 cm;

- The thickness of filling over the spring block is more by 1 cm, which significantly increases the comfort level of the berth;

- legs are solid, arc-shaped, provide a higher level of stability;

- the mechanism is attached to the steel frame, which avoids unintention of the mechanism after a certain period of operation.

Benefits

Among the main advantages that distinguish the mechanism of "Sedaflex" among others, we can mention the following:

- when folded, the structure occupies a small space, which is important for small apartments;

- an uncomplicated transformation system that does not require special skills and physical strength - the child can even decompose the mechanism;

- the system unfolds almost noiselessly, so that the transformation of the sofa can be carried out even in the middle of the night;

- The maximum size of a sleeping place in dimensions and weight is calculated taking into account two adults (can withstand up to 200 kg and is suitable for growth up to 190 cm);

- in the process of transformation, the mechanism does not harm the floor covering.

disadvantages

When choosing a folding sofa, you should pay special attention to the quality of the material used and the strength of the attachment, since under the guise of a convenient and practical product, a cheap forgery may be hidden. Particular attention deserves the mechanism of the sofa "Sedaflex". Customers' comments about this mechanism have a negative connotation. Why is this happening, since the original transformation mechanism was developed taking into account the basic needs of consumers, and the inventor emphasized the comfort, mobility and durability.

First of all, this is due to the work of unscrupulous producers and their desire to save on materials.

If the steel in the structure is thinner than the recommended standards, eventually it wears out and the mechanism loses stability.

The steel frame of the mechanism must be fixed to a wooden base. Some manufacturers use soft rocks, and during operation bolts loosen and fall out of the socket.

Special attention should be paid to the mattress, which is a direct indicator of the level of comfort. What springs are used? Is the thickness of the spring-loaded layer sufficient, or will you feel their turns in each part of your body? What material is used for the inner layer and upholstery? A poor-quality mattress quickly loses its shape and is rubbed along fold lines. After 5-6 years, it becomes impossible to sleep on it.
