Abstract

The invention discloses a sofa. The sofa comprises a framework, wherein a plurality of elastic metal plates are installed in the framework in parallel, two ends of each elastic metal plate are fixed to the framework, the elastic metal plates are covered with rubber pads, and the rubber pads are covered with sponge pads; each elastic metal plate comprises a lower concave part and an upper convex part which are arranged at an interval, a connecting part is arranged between an adjacent lower concave part and upper convex part, and the connecting parts between the adjacent elastic metal plates are connected through a connecting piece. The sofa is advantaged in that defects in the prior art can be overcome, and the service life of the sofa is effectively prolonged.

Description

technical field [0001] The present invention relates to a kind of furniture, especially a kind of sofa. Background technique [0002] Sofa is an essential kind of indoor furniture. In order to create good comfort, the existing sofa is usually realized by installing cushion springs. However, this kind of spring structure will undergo irreversible deformation after being used for a long time or subjected to a large impact force, which is manifested by the concave deformation of the sofa. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sofa, which can solve the deficiencies of the prior art and effectively prolong the service life of the sofa. [0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows. [0005] A sofa, comprising a frame, in which several elastic metal plates are installed in parallel, the two ends of the elastic metal plates...
