A cushioned support has a rigid base and a molded resilient cushion. The cushion is releasably attached to the base with a wrap-around lip or by means of a retaining member disposed along a periphery of the base. The retaining member, if used, may be conveniently manufactured as an extrusion with a first portion for attachment to the perimeter of the base and a second portion having a barbed cross-section for engaging the cushion.
