Abstract
Abstract A patient and infant support pad and bolster are each formed of a flexible closed cover of generally rectangular configuration forming a chamber which is filled approximately 50% to 70% of its normal volume with relatively small expanded polystyrene beads. The pad and bolster have unexpected shape conforming qualities and support characteristics which permit the maintenance of several positions for an infant including the semi Fowler's, right lateral, postural drainage, and prone positions while minimizing the prospects of flat head syndrome, or pressure sores.
