Abstract
A unitary support pad constructed of synthetic foam is described especially for use as a mattress pad for hospital patients. The pad has a number of discrete upstanding projections being independently compressible and formed in the pad so as to provide a generally flat surface with voids between the projections, preferably extending entirely through the pad, formed by compressing the foam, in discrete areas, which is severed as through the action of a transverse band saw while compressed.
