SOFA MECHANISMS

How should a sofa mechanism be selected?

A sofa mechanism should be selected by defining the intended function first: standard seating, deep seating, relax motion or bed function. Frame size, wall clearance, assembly method, technical drawing availability and quality standard should then be evaluated together.

How should a sofa mechanism be selected?

Which function is required?

A simple and durable frame structure can be enough for standard seating. For bed functions, opening dimensions, locking requirements and movement ergonomics become more critical.

For relax and deep-seating solutions, upholstery, foam and frame tolerances should be considered together with user comfort.

Why are technical documents important?

Technical drawings, assembly schemes and foam dimensions help manufacturers move from prototype to mass production faster. These documents reduce the risk of incorrect drilling, incompatible connections and unnecessary revisions.

How is the right product family matched?

Wall-hugger applications should be matched with zero mechanisms, comfort-focused openings with relax mechanisms, compact spaces with tekyat mechanisms and multi-function seating-bed use cases with the CSS series.
