Claim:
A seat cushion comprising: a unitary foam cushion formed in a one stage foaming operation and having a body with a first foam density and a perimeter section with a second foam density higher than said first foam density, said perimeter section having an outer surface defining a periphery of the cushion; a cover disposed over the cushion and having a border extending around the periphery of the cushion; an insert molded within the cushion and having an outer wall extending along, parallel to and spaced from the periphery of the cushion thereby forming a boundary between the body and perimeter section of the cushion so that the first foam density cushion body engages one side of the insert outer wall and the second foam density perimeter section engages the other side of the insert outer wall, and said outer wall thereby defining the perimeter section as having a relatively small and generally uniform cross dimension; the cover being bonded to the periphery of the cushion; and a cushion support wall having a size and configuration to receive the cushion and cover, with the border of the cover disposed within the support wall.
