PURPOSE:To improve the cushionability of the seat body or the back rest without making the seat body or the back rest large in size and without raising excessively the manufacturing cost. CONSTITUTION:On one face of a base plate 3, a cloth-like or net-like elastic supporting body 6 having flexibility is extended and provided in a state separated suitably from one face of the base plate 3, and a cushion body 7 is formed integrally on the base plate 3 in a state that the elastic supporting body 6 is covered. The cushionability is improved by existence of the elastic supporting body 6. Also, since the elastic supporting body 6 is in a state embedded in the cushion body 7, the seat body 1 does not become oversize. |
