Abstract
Abstract A pad for supporting a recumbent human being comprises a substantially planar substrate formed of a resilient material and having first and second regions of lateral grooves extending substantially thereacross. The first region of lateral grooves defines a first shoulder support area and the second region of lateral grooves defines a tail support area. The remainder of the substrate defines a general support area which may have convolutions formed thereupon. A third region of lateral grooves may extend substantially across the substrate to define a second shoulder support area such that said first and second shoulder support areas are generally symmetrical with respect to the tail support area in order to facilitate of either end of the pad as a head end. A less resilient peripheral region may optionally be formed about the periphery of the pad to provide a means for helping to prevent incapacitated persons from rolling off of the pad.
