1. A mattress unit comprising a hollow inflatible base support having a plurality of resilient upstanding support cells arranged on the upper surface of the base support, the tops of the cells being adapted to support a human body such that depression of one cell by weight of the human body will not depress adjacent uncontacted cells, thus avoiding substantial horizontal forces against the human body, the support cells being covered by a cover defining a gap between the support cells and the cover, said cover having a like configuration as said upper surface of said base support, and an inlet to allow gas under pressure to said gap, the cover being perforated to allow gas to escape upwardly.
