Abstract
A method of making a seat (10) includes preassembling the seat by positioning a seat cover (26) over a contoured foam substrate (18) with a layer of heat activated adhesive (24) between the seat cover and the foam substrate. Securing the seat preassembly (10') in a fixture (106) and introducing heating fluid into the fixture to pressurize a flexible bladder (156) against the seat. The pressurized bladder urges the seat cover against the contoured foam substrate and heats the adhesive layer. Next, cooling fluid is introduced into the fixture to pressurize the flexible bladder against the seat, and the pressurized bladder urges the seat cover against the contoured foam substrate and cools the adhesive layer.
