Description

technical field [0001] The invention relates to a kind of furniture, in particular to a stretchable and deformable sofa bed.

The position of the sofa backrest is usually fixed or can be adjusted within a small range, so ordinary sofas can only provide the function of "sitting". In recent years, some folding sofa beds have appeared. The backrest of this type of sofa bed can be flattened to realize the function of a bed; Plates, support plates, ratchets and pawls, etc., often have complex structures, low reliability, and are easily damaged. In addition, this kind of folding sofa bed only has the functions of "bed" and "sofa", but does not have the function of lifting the legs to make them relax, so there is still room for improvement. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the...
