In a method of manufacturing a permeable seat cushion, a seat surface covering of premeable fabric material of bag-like structure is formed by joining a seating portion to side portions, and the seating portion of the seat surface covering is pressed in a turned-over relation between a pair of dies after application of heat thereto. A skinless molded block or profile-cut slab of foamed polyurethane is then bonded to the seating portion, and the side portions are turned over to complete the seat cushion. |
