Abstract

A seat assembly comprising a molded foam cushion having laterally spaced bolster portions, a molded plastic pad secured to the bottom of the cushion and having a fine grid and at least two heavy strands. There are openings in the cushion directly above the heavy strands which locate and receive hooks for securing a trim cover to the heavy strands through the cushion. The cushion is secured to a seat frame having seat surface springs.

2. Apparatus as defined in claim 1 wherein the cushion comprises a center portion of a first thickness bordered on each side of bolster portions of a second greater thickness, the junctions between the center portion and the bolsters lying vertically over and being substantially coextensive with the heavy strands.

3. Apparatus as defined in claim 2 wherein the cushion has formed in said junctions vertical openings to admit fasteners to fasten the trim to the heavy strands.
