To the sofa is convenient and durable, you need to choose the way to transform its transformation. We will tell all about the mechanism of Dolphin and help make the right choice!
What is Dolphin
Initially, the mechanism of transformation of the sofa dolphin was used only in angular systems, where it was very in demand, because it allowed to get the most spacious place to sleep. Later, he was successfully used to apply for direct varieties, including small bedrooms. It refers to the type of roll-out, and in the case of an angular option does not require additional free space for folding.
It consists of two elements, one of which is in the disconnected section, and the other in the seat. The transformation mechanism is a solid steel construction installed on wooden guides. It works simple enough. In the process of folding from under the seat, two blocks are rolled out, one of which is recessed in another. It is they who form a spacious mattress.
Through the levers and springs system, one of the sections rises to the level of another, where it is securely fixed. There are several variations of such structures, but the principle of their action is unchanged. The durability of the product largely depends on the quality of the material from which the frame is made. If it is cheap low-quality steel, there is a high likelihood that during operation it is deformed and fails.
Design features
Dolphin variatives and can have many modifications. Dimensions of products are different: from small transformers to multi-seat corner sofas. Armrests can be made of wood, "soft" or absent at all. The models are especially in demand by the shelves embedded in armrests, small boxes or niches. The built-in backlight is found, which is not very functional, but beautiful.
Structurally, all systems are divided into three large groups:
- Straight. Furniture of various sizes, folded forward. Its distinctive feature is the lack of a box for storing clothes, since the space under the seat occupies a roll-out platform.
- Corner. Equipped with the withdrawal angular section. Here it is necessary to have a storage compartment, which is very convenient. In some models, if necessary, the angle can be changed.
- Modular. It is assumed the presence of several blocks differing in size and purpose. With their help, you can collect functional systems, ideally suitable for certain rooms.
How the sofa dolphin unfolds
Regardless of the type of furniture, the transformation process into bed occurs equally. It is performed for three simple steps.
- Remove the pillows from the seat, if they are present in this model.
- We do for a special looting or pen and completely pump out the bottom block. In some models, the characteristic click is distributed.
- Raise the bottom of the module up and pull on yourself. As a result, the section rises and becomes one level with a seat, forming a sleeping place.
To fold the design, it is enough to do all operations in the reverse order. First you need to lower the extended element, then roll the section into place. If there are pillows, they are placed on the furniture. If the mechanism is working, all manipulations are carried out without much difficulty. True, in order to raise the retractable block you will need to make some effort. But for an adult, they are insignificant.

Why choose such furniture
A variety of variations of the donkey dolphin are very in demand. This also applies to corner models, and to straight and modular. Of the most significant advantages, it is worth noting:
- Ability to use in the room of any size. Such a sofa is compact enough, but in the unfolded form gives the most spacious space for sleep. It can be installed close to the wall or at some distance from it, thereby exercising zoning the room.
- Easily use. The transformation process is very simple. It does not need to raise the back, as for books or deploy blocks, like accordions. To decompose the dolphin, you just need to roll out the section and lift it up to the seat level. True, you will have to make a slight effort that can be too big for a child.
- Comfortable sleeping mattress. It will be such if a model with a high-quality assembly is purchased. Since the joint of the two sections is present, the height difference is possible, which will be felt by a lying person. If the assembly is carried out correctly, the differential will not and the user will receive a smooth comfortable mattress.
- Reliability and durability. Dolphin mechanism in the sofa, whose video review is easy to find on the Internet, durable and suitable for long-term operation. It is only necessary to comply with the manufacturer's recommendations and perform all manipulations with furniture very carefully. On average, the design withstands the minimum of 1000 transformation cycles. The higher the quality of the material and the assembly, the longer they will serve.
Corner and modular systems have another advantage in the view of a roomy storage box for storage of bedding. It can be located only in the angular section or in the submissive module, since the space under the seat of the standard product is fully occupied by the roll-out block.
Possible problems and how to solve them
Significant flaws in the design of a little. These include a common problem with a potential danger to spoil the flooring with the rollers of the retractable section for all roll-out products. Therefore, if the room is set to laminate, parquet and the materials similar to them need to be traced so that the videos are made of soft rubber or silicone. They will not harm the finish.
It is undesirable to put such a sofa on the carpet. The soft cloth will interfere with roll out the block. And if the pile is high, there is a possibility that the threads are wound on the axis of the rollers. It hurts them normally rotate and give an additional unwanted load on the frame. If it is made of low quality steel, it is possible to skew the frame and even its breakdown.
These are the most significant advantages and disadvantages of the design. The breakdown is also possible, like any other furniture. To prevent them, manufacturers are recommended to properly care for the product. In addition to regular cleaning of the upholstery, it is planned to carry out a whole range of events:
- Cleansing the transformation nodes from pollution and moisture. This will prevent the emergence of rust and the accumulation of dirt, which will prevent the normal operation of the mechanism.
- Lubrication of rubbing parts. They must move freely on the guides, otherwise the system can deform.
- Cleaning the rollers and axes on which they are fixed, from garbage and pile. Especially relevant for furniture, which stands on the carpet of the coating.
And a few more useful recommendations. It is impossible to place under the sofa any items, even small. They can interfere with the system normally function. If in the process of assembly or disassembling furniture suddenly some difficulties appeared, you do not need to try to finish the process at any cost. Excessive pressure, jerks and excessive efforts can lead to a breakdown of moving parts. According to the instructions, it is best to return everything to the original position and carefully repeat an attempt.
How to choose "Right" design
When choosing the optimal system for your home, it is necessary to take into account the internal filling, which determines the degree of comfort of furniture and its durability. There are two filling options: flawless and spring. The first implies the use of foam rubber or polyurethane foam of various brands. A more durable and easy-to-use last, which is a good alternative to spring systems. Porolon is less elastic and quickly loses its properties.
Filling with spring elements is also two types. Constructions with dependent details are a kind of "snake" from the springs, each of which is connected to the neighbors. Such mattresses of elastic, quite well take the form of the body, but exactly until the moment as one of the elements break. Following this, sending, loss of form appears. In some cases, sharp edges of details can penetrate the upholstery outside.
Maximum convenient and durable blocks with independent springs. Here each element is enclosed in an individual case. This allows the mattress to take a form as possible for lying on it. Such products are considered orthopedic, most comfortable for full sleep.
Dolphin sofas are considered one of the most sought-after. They are chosen for living rooms, kitchens and even bedrooms. But it is necessary to understand that they can be a full-fledged bed replacement only under the condition of the correct selection of filling. Optimally, if it is an orthopedic unit from independent springs.
