Abstract: A method of seam location using a vacuum in which a laminate structure is formed having a cover member with a backing material bonded thereto. The cover member is comprised of multiple pieces joined together forming seams which are bound by a non-permeable binding. The cover member is placed on a holding tool and held in place by a vacuum applied to the area of the seams whereby the non-permeable binding is drawn against the holding tool, holding the cover member in place while a backing material is bonded thereto.

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.
