A cushion is obtained by impregnating an aqueous polyurethane polymer emulsion in three-dimensionally interwined fibers, removing an excessive aqueous poly- urethane polymer emulsion and hardening the resultant material with heat. The surface of each fiber is covered with a polyurethane resin, and the fibers are bonded by the polyurethane resin at intersected portions of the fibers.
