Benefits of technology

The present invention is a unique sofa design that has a light structure, smooth folding and unfolding operation, and minimal space occupation. The sofa body is directly supported by movable front and rear support rods, and is made from a soft fabric. The seat cushion is lifted by the backrest and armrest, which makes it comfortable to sit and does not occupy collection space. The folded front and rear support rods can be nested with each other, and present a flat structure. Multiple folding sofas can be conveniently superposed for collection, which occupies less space. The invention aims to provide affordable and effective elements and arrangements for the purposes described.

Problems solved by technology

A defect of the structure is that the seat is not stable, especially when the buttock gravity moves backward, the seat will tilt backward.
In the prior art, the seat cushion of the folding chair is made from hard materials or needs reliable support, so that its structure is complex.
