ABSTRACT:
A mattress is disclosed which eliminates components by combining structural integrity, air-impervious and insulating functions, thereby significantly reducing overall weight and increasing portability. In a particularly preferred embodiment the mattress is self-inflating. The semi-rigid cover provides the dimensional rigidity necessary to effect self-inflation. The increased thickness of the utilized cover component affords improved puncture resistance.
