ABSTRACT:
A method and structure for manufacture of a foam cushion article. The method of constructing the cushion article does not require the use of a conventional mold and is performed by placing a frame within the space to be filled with foam. Fabric is then disposed around the frame in a step toward the formation of a preselected geometric shape for the cushion article. Subsequently, a skeletal assembly is positioned externally against the fabric in a final step to achieve the preselected geometric shape. The method allows production of a structure which includes selected areas of fabric bonded and unbonded to foam material. The method also allows substantial degrees of freedom in generating and positioning regions of preformed cushions or of different density foam cushions and in controlling overall strength and bonding between the different cushions and the fabric.
