Sofa bed mechanisms options

Pantograph and dolphin mechanisms are suitable for continuous sleep - there are no metal structures there

Pantograph

The mechanism for unfolding the sofa, called a "Pantograph," is a modified version of the popular "eurobook" design. At its core, this design features a hinge-rotary mechanism, with one side attached to the stationary frame and the other to the movable part of the sofa (the seat). The side parts of the structure rotate 180 degrees during unfolding. In the process, the legs, along with the seat, move along an arc and lower onto the floor, providing access to the storage compartment for bedding and allowing the placement of the second half of the sofa. To prevent tilting during the transformation into soft furniture, a special spring and synchronizing rod have been added.

French click-clack sofa

A "French click-clack sofa" is a term used to describe a sofa transformation mechanism in which the sleeping surface is formed by a hidden mattress located under the seat. This mattress unfolds in three stages. A modern "French click-clack sofa" can be either a regular (straight) sofa or a corner sofa. It is a versatile, comfortable, and stylish piece of furniture.

Seda-Flex

A "Seda-Flex" or "American click-clack sofa" is a transformation mechanism in which the sofa unfolds forward in two steps. The sleeping surface is formed perpendicular to the sofa's backrest. The Seda-Flex mechanism is designed for daily use and allows the sofa to transform into a double bed with minimal effort. The bed's base features orthopedic slats, and the footrest is made of elastic straps. The slats (lamellae) provide sleeping comfort, while the straps offer comfort for sitting.
