Abstract
The method of making a cushion assembly uses a trim layer and cushion pad with an adhesive therebetween. The adhesive is a hot melt adhesive applied to the contoured surface of the cushion pad and reheated on the cushion pad prior to use thereof in the subject process. An adhesive activator is applied to the trim layer, which had been previously placed on a mold. The cushion pad and trim layer are compressed against one another with the adhesive and activator therebetween to bond the cushion pad and trim layer together.
