ABSTRACT:
A vacuum formed, foam-filled seat or back cushion having a covering and an inner portion comprised of a first type of foam further includes an insert comprised of a second type of a softer foam for use in high pressure areas in the support surface. The surface of the cushion is contoured in accordance with an intended user's dimensions and support surface configuration for improved user support and comfort, particularly for a non-ambulatory, handicapped person. The softer foam insert is formed integrally with the remaining foam portion of the cushion to provide a smooth, continuous, secure support surface. The cushion's covering is formed about the foam insert in a manner which prevents stretching or tearing of the covering due to the difference in firmness of the underlying foam portions. The cushion includes a rigid base formed integrally with the foam core as well as rigid internal lateral reinforcements for user support and seating stability. Provision is made during cushion formation for the inclusion of lap belt slots and an incontinence relief tube extending through a seat cushion as well as undercut front edge for a user with tight hamstrings.
