ABSTRACT:
A lightweight contoured base for a seat cushion is produced by first forming a shaped lightweight foam core with a void corresponding to the ischial tuberosities of a user and then forming a sandwich assembly by placing a layer of foam or foamable material against both upper and lower surfaces of the shaped lightweight foam core to form a sandwich assembly. The sandwich assembly is then molded to produce the finished contoured base for a seat cushion.
