A seat member providing a support structure of a seat in a vehicle is integrally formed of a synthetic resin material and includes a seat base portion and wing or flap portions. The seat base portion is formed with a plurality of openings and is partly thinner than the remainder to provide desired resiliency. The flap portions are formed with a plurality of openings or corrugations and are also partly thinner than the remainder to provide additional resiliency. Portions functioning as suspension springs may be integrally formed with the seat base portion together with a frame including upper rails of a slide rail unit. Reinforcing wires may be embedded in both the seat base portion and the flap portions.
