摘要： A vehicle seat (1) includes a seat cushion (2) and a seat back (3), in which the seat cushion (2) is given a stiffness distribution in a front-rear direction in such a way that a front part of the seat cushion is provided with a low stiffness region (PSc) which is more flexible than a rear part of the seat cushion being a high stiffness region (PHc).
