How an angular sofa unfolds: basic mechanisms, type of transformation

When purchasing a sofa, everyone buys furniture for the longest possible period. A sofa, among other things, can have a folding mechanism, which is an important part of its functionality. Today we will pay more attention to the folding mechanisms, their types and transformation.

The main mechanisms for folding sofas

There are several types of sofas, with different types of folding - these are models:

• Retractable. They work on special rollers that allow turning the sofa into a berth in one motion;
• Folding. Such structures are laid out, hiding the soft elements of the berth inside;
• Expandable. This type is similar to a folding, but with some differences: the elements of a berth can have special mechanisms for deploying and raising them to the same level as a sleeping lodging.

In addition to the main types of folding, there are “exotic” ones, but they are extremely rare and only for unitary design tasks and solutions. Sometimes furniture designers design standard types of folding furniture.

Types of sofas by type of transformation

Transformation - The completed process of converting the sofa into a berth. Estimated by the final result and depends on the type of mechanism.

There are such basic types of transformation:

• Book. This species was present in almost every Soviet couch. The furniture in this case has two positions: a sitting position and an overnight position (bed). The pluses include the fact that usually the bottom is not involved in mechanical processes, which allows you to place various accessories for sleeping. And also sometimes a gap is left between the wall and the upper part of the mattress in order to be able to lay out the sofa. This type of transformation is reliable and unpretentious details;
• Click Gag (Tango). A very similar type of transformation with a “book”, with one difference: the upper mattress can be adjusted to the angle you need. Otherwise, this is the same “book”, with its advantages and disadvantages, with its ability to store bedding in the bottom. Details for the transformation have a more complex structure, due to the presence of a tilt angle lock;
• Accordion. This type got its name because of the external similarity to the accordion of the same musical instrument. In the upper mattress there is a folding division into two parts, and in the lower - the ability to move forward, thus creating a collapsible bed. For the "accordion" will require more space for transformation, which can be attributed to the minuses. Bed linen can be placed in a special box, which can occupy exactly half the bottom, which, of course, is the positive side of the structure;
• Dolphin. How is a corner sofa laid out? Because of its design features, "Dolphin" is one of the most popular transformation mechanisms for corner sofas, it allows you to not use the upper mattress. In the bottom there is an additional mattress that extends from the bottom up, forming a solid place for the night. The disadvantages include the complete inability to use the bottom for their own purposes (except in the open condition, but this is rare and this is impractical) and some complexity of the level equation mechanism mattresses. This is compensated by the ease of use and the pleasant appearance of the folding process itself;
• Eurobook and others. “Eurobook” also has two provisions (“dream” and “sofa”), akin to the usual “book”. Only the transformation process itself is different: the lower mattress rolls forward on the rollers, forming a place for the upper mattress, which simply lowers into the formed place. As in the "book", you again have access to the bottom for using it for personal purposes. You will also need a seat in front of the sofa in order to be able to expand it, but the model can be pressed close to the wall - this will not complicate its transformation.

What is the most convenient folding mechanism?

The most convenient transformation mechanism is a mechanism that allows you to get the fastest result, without complex manipulations.

Traditionally, the “eurobook” is considered the most convenient. Its design is simple, reliable and allows you to quickly form a berth. Also, it is easy to clean and lightweight.
