An inflatable enclosure useful as a matress is described which has first (bottom) and second (top) broad surfaces connected at their edges to form the enclosure, the bottom being formed of a substantially air-impermeable resilient closed-cell foam wherein the thickness and density of the closed-cell foam has been selected to provide semi-rigid characteristics between adjacent points of support and the top being formed of material selected from an air-impermeable resilient closed-cell foam and a flexible air-impervious material, said first surface being connected around its edges to a flexible air-impervious material which is in turn attached around the edges of the second surface to form the enclosure, the enclosure having at least one closable means for admitting a fluid to and releasing fluid from the enclosure. |
