Without it, it is impossible to imagine a dwelling, it often decorates the design of an office, under certain conditions it is part of the design of a loggia, not to mention the arrangement of a summer residence. Among the large selection of models, sofas with the “Dolphin” mechanism are in great demand among buyers.

The design of the mechanism "Dolphin" refers to the sliding, for some manufacturers has the second name "Kangaroo".Such a transformation mechanism was originally invented for corner models, but due to high demand, trademarks began to produce linear (straight) versions with rollers.

The transformation of the mechanism occurs by pulling the lower unit, hidden inside (with the help of a secret loop, located under the seat). To expand the sofa, you need to pull the loop, push the block all the way: then it will rise to the desired height and take the correct position. In this case, the seat and back (if not equipped with special cushion-blocks) remain in place and do not move. In fact, an additional block is added to the sofa, which increases the surface of the bed.

The unit is hidden in a box, has rollers, rolls out easily. To turn the sofa into a bed, it will take a few seconds. The design is quite simple and convenient - this explains the popularity of such sofas. Folding represents the reverse procedure: first, lift the unit, taking it by the loop, then lower it down and roll it into the lower box under the seat.

Such products are included in the line of the most popular models of folding sofas. It is easy to assemble and transform, does not require a backrest lift, as in the “book” system or reversal of blocks, like an accordion. This mechanism is the main component of the design of the sofa, it affects the convenience of transformation.

There are three types of sofas with the mechanism "dolphin":

• straight;
• corner;
• modular.

Each of them has its own differences, but they are all universal and not capricious when choosing a location: you can put any of them both near the wall and in the corner, and even in the center of the room, thereby delimiting the room into zones (for example, a game room, a living room). , lunch).

Direct models with the "dolphin" system are not equipped with built-in compartments for clothes, which usually store pastels. Instead, there is a bed block in the box itself.

Such sofas are considered classics, they are both compact and large size. A feature of direct sofas of this type is the presence of additional functions and the ability to add armrests to the design.

Angular type of sliding model is relevant for rooms in which literally every centimeter of useful area is important.. These sofas very effectively involve space, as much as possible arranging a corner of the room. Often, manufacturers provide for the change of the angle, which simplifies the permutation and allows the systematic transformation of the model at his expense. In this design there is a linen box, which is located at the bottom of the added angle.

Modules - an unusual version of the sofa with the system "dolphin". With their help, you can create a variant of upholstered furniture with different functionalities depending on the number of components. In this case, different combinations are allowed, but the principle of the mechanism remains the same.

Sofas with the mechanism "dolphin" produce two types: with springs and springless unit. At the same time, folding structures in the unfolded form are not inferior to a full-fledged bed with a large berth.

That mats are responsible for the rigidity of the sofa. Depending on the choice of filler, the sofa can be:

• soft (not intended for children and people with greater weight);
• medium hardness (the optimal choice of the main part of buyers, calculated on the average weight of two people);
• tough (A special type of mat made on the principle of a combination of layers, suitable for people with diseases of the musculoskeletal system).

In the production of soft backrest and seat mats use a soft filler. Products with a rigid spring block are distinguished by a more complex structure that ensures the correct position of the spine in both sitting and lying positions (regardless of the number of people who are sitting on the sofa).

Dimensions of sofas with the dolphin system are different for each company.Each manufacturer sets its own standards. In general, sizes depend on the type of model (straight, angular) and shape. The sofa can be small and even mini, medium size or large (double and spacious).

The most sought-after design is a model with a bed dimensions of 160x200 cm and 180x200 cm. Such a space is convenient for both one and two people. These are medium-sized models, which are often purchased as a guest option. Their depth is 105 cm, height is about 85 - 90 cm, width of armrests is about 60 cm, and the height of the sleeping bed is 44 cm. When assembled, they do not take up much space and do not seem massive.

Large, double models are a bit more spacious: their parameters are 190x200 cm. Small options are close to a bed size of 90x150 cm. These sofas are not designed for two, but they are an excellent alternative to a spacious bed for one place.

In the production of sofas with the "dolphin" system, metal and wood are used for the frame, mat filler and upholstery to give a beautiful appearance.

Sofa filler is of several types. It may be of natural or synthetic origin. In addition, the structure of the block is also different: it is of spring and springless type.

As fillers for sofas with the "Dolphin" system, manufacturers more often use two types of foam rubber and a spring block. In addition, depending on the model, a layer of felt, coir (coconut fiber), padding polyester and less often (for additional soft pillows) sintepukh and holofiber may be added to the design.

This type of construction is convenient, it is distinguished by a relatively moderate price, and there are two types: using standard type T foam rubber and HR foam. The first option is less practical and not intended for daily use, the second is an alternative to the spring unit.

The spring block is more reliable, it is durable, resilient and is made using dependent and independent type springs.They can be placed horizontally and vertically, resemble a metal base or a full mesh with vertical springs.

The independent type of springs is different in that each of them works by itself and does not connect with nearby ones. The block consists of springs packed in textile covers interconnected.

In the production of sofas with the mechanism "dolphin" they use the same materials as for the entire line of upholstered furniture. Genuine leather stands out from luxurious materials.. Furniture with such upholstery is very expensive, although more practical (it is easy to clean it from dirt, dust and moisture).

In addition to leather upholstery manufacturers use eco-leather and leatherette. Such furniture is beautiful, but less practical and more prone to abrasion.

The main line is made using textiles. This series includes furniture tapestry, flock, jacquard fabric. Textile upholstery is very colorful and allows you to vary any style of the room. However, it also has disadvantages: it is more susceptible to abrasion, short-lived and impractical. Therefore, when buying a sofa with textile upholstery, you can not do without protective covers or capes.

Sofas with the Dolphin system are also convenient because they can be repaired. As soon as a failure of the mechanism is noticed, a cover needs to be replaced or several springs have become unusable, the model needs to be reanimated. You can do it yourself, at home. And if you do not neglect the breakdown, you will be able to save the sofa from major repairs or buying a new one.

Disassembly instructions are simple and do not require complicated manipulations, because the mechanism itself is quite simple. First, remove the pillows (if any) and covers, then push the furniture into the middle of the room, lift the seat. Then remove the side elements, separate the parts, determine the degree of damage.

If it’s just a matter of replacing the block, it’s done like this:

• remove the brackets fixing the upholstery material;
• remove the protective cover unit;
• change the unit if it is beyond repair (cut out a new one or order it ready according to the necessary measurements);
• if the problem is in the springs, they are carefully unscrewed with pliers, then they are replaced by new ones bought in a specialty store;
• A cover is put on the block, then they are assembled in the reverse order of disassembly.

If the problem with the rollers, they are replaced by new ones. A broken mechanism needs to be completely replaced. To do this, you can contact a specialist or replace it yourself. It does not take a lot of time if you take care of the necessary system in advance by purchasing it in a store.

Repair is made as follows:

• unscrew the old broken mechanism connecting the seat and back of the sofa;
• In its place a new one is inserted, fixing the structure in the same holes.

It is necessary to try that the back and the seat were lying in the same plane, otherwise the surface of the bed will not be even.

No matter how careful and careful the operation of the furniture is, it is important to understand that you cannot do without care. This is not only cleaning upholstery, removal from not dirt, dust and moisture. It is necessary to take care of the mechanism of the sofa itself, otherwise the service life may be shortened, the system will quickly become loose or jam.

To avoid this, it is worth considering a few simple recommendations:

• the mechanism needs to be cleaned of dirt and moisture in order to eliminate the formation of rust and obstacles in the work of the transformation mechanism;
• the running gear should be lubricated from time to time.otherwise, they may act on each other, distorting the whole system;
• there should be no foreign objects under the sofa - they can disrupt the work of the transformation mechanism;
• if suddenly the system began to work with failure, it is impossible to put pressure on it, making every effort - this will lead to a breakdown of the mechanism. It is better to push the sofa and try again to expand it;
• if there is a carpet on the floor, it is worth regularly to clean the pile from the rollersOtherwise, they will quickly become unusable, which will lead to the need to repair the mechanism.

In addition, you can get stylish capes that will keep the upholstery and bring fresh colors to the interior style.
