Full-sponge compressible sofa

Abstract

A full-sponge compressible sofa includes a sponge mounting seat and at least one sponge sofa seat provided on the sponge mounting seat. The sponge mounting seat includes a base and two armrests symmetrically arranged on the base. Each armrest includes an armrest main body and a limiting flange provided on one side of the armrest main body. Each sponge sofa seat includes a seat cushion and a backrest provided on one end of the seat cushion. The side of either one of the armrests provided with the limiting flange faces the other armrest. When the sponge sofa seat is mounted on the sponge mounting seat, the limiting flange of each armrest abuts against the seat cushion of one sponge sofa seat, so as to limit the position of the sponge sofa seat on the sponge mounting seat.
