Abstract: ABSTRACT OF THE INVENTION           A method of manufacturing a portion of a vehicle seat assembly utilizing a stylized forming tool and bonding a seat cover to a foam seat bun having a predetermined surface contour. The seat cover is positioned exterior side down on the stylized forming tool.  A film of air impermeable material is then placed over the seat cover and a vacuum is applied between the impermeable material and the forming tool so as to draw  the  seat cover down  into substantial  conformity with style lines on the upper surface of the forming tool.   The impermeable material  is then removed and an adhesive coated foam seat bun is positioned and compressed against the seat cover on the forming tool.  Once the seat cover and the seat bun are bonded together by the adhesive, the seat assembly is removed from the forming tool.  The outer edges of the seat covers are then fastened together or to the underside of the seat bun so as to complete the assembly of the seat portion.
