Compressed sponge self-inflating cushion

Abstract

The present invention relates to the field of outdoor appliances, in particular to a compressed sponge self-inflating cushion. The self-inflating cushion of the present invention has a wide range of applications, and can be used both indoors and outdoors, and a sponge automatically absorbs air, so that automatic inflation is achieved. There is no complicated electronic circuit inside, so there is no need to worry about whether an inflatable cushion body cannot be inflated due to electric leakage or insufficient power supply. The surface of the sponge is provided with a plurality of parallel folding grooves for convenient folding and winding, and thus a user can conveniently wind up the inflatable cushion body.
