Abstract
A vehicle seat assembly having a molded foam cushion body and a pair of molded foam bolster bodies covered by a cover member which is bonded to the cushion body and the bolsters during molding. The cushion body foam is poured in place onto a portion of the cover member and the foam for the bolster bodies is poured in place adjacent the cushion body preferably at the same time. The bolster bodies can thus have a density differing from the foam cushion body to provide differing deflection characteristics in the bolsters than in the cushion body.
