摘要：
A multilayered seat having different hardnesses, breathable face material with a good surface touch and a hardness capable of bearing a body weight of a person who sits on the seat. A seat (1) comprises a shaped body of foam covered with a breathable face material (2). The shaped body comprises a first foamed member (10), which defines a base of the body, and a second foamed member (6), which is made integral with a back surface of the face material and a surface of the first foamed member by pressurizing and compressing a liquid foaming mixture, which is projected on and laminated on the first foamed member and has undergone gaseous reaction but remains in a fluid state, by means of the first foamed member and a pressure die, which is disposed on the face material above the liquid foaming mixture, shaped to be the top portion of the seat and provided with suction ports, while performing suction through the suction ports of the pressure die.
