摘要：
A cushion has a main body formed of fibers including organic synthetic fibers which are stereoscopically intertwined. A cured polyurethane resion covers surfaces of the fibers and binds the fibers at their intersections. The cured polyurethane resin is obtained by curing a polyurethane prepolymer with water or steam.
