Abstract
A pressure relief pad for use by persons suffering from or subject to the formation of decubitus ulcers or bedsores is described. The pressure relief pad is made from viscoelastic foam layers which provide for the redistribution of pressure around an affected or wounded area allowing the wound to heal faster. The contoured viscoelastic foam pad can be positioned over a separately applied dressing or an exudate absorbing material can be included in the pad. The contouring for the pad may be achieved by molding the foam as desired or by using a multiplicity of foam layers joined by adhesive to form the pad.
