The method of producing a cushion assembly includes bonding a foam pad to a cover material with a heat-activatable adhesive layer and an electrically conductive layer therebetween. The cover material is placed in a contoured mold with the adhesive layer and the electrically conductive layer placed thereover and in heat transfer relationship to each other. The foam pad is placed thereover and the electrically conductive layer is energized to heat and activate the heat-activatable adhesive layer to allow bonding between the foam pad, the cover material and the electrically conductive layer.

[ What is claimed is:] [1.] A method of joining a foam pad to a cover material having an appearance portion and a concealable portion, the method comprising:forming the foam pad such that the foam pad includes an integrally formed electrically conductive polymer;positioning a heat-activatable adhesive layer between the cover material and the foam pad such that said heat-activatable adhesive layer and said electrically conductive polymer are in heat transfer relationship to each other;energizing said electrically conductive polymer to generate heat; andjoining the cover material and the foam pad together sufficiently with said heat-activatable adhesive layer therebetween such that heat from said electrically conductive polymer activates said heat-activatable adhesive layer for adhering the concealable portion of the cover material and the foam pad to one another while exposing the appearance portion of the cover material.
