A seat cushion includes a seat cushion base layer which biases two base support parts in directions approaching each other, and has base support part elastic members which are elastically deformed in an up-down direction, thereby causing the seat cushion to have a configuration having a high spring characteristic. In the seat cushion and the seat back, the seat cushion is configured to be set to be larger than the seat back regarding a range of connecting an origin, a maximum displacement point, and a maximum load point, and a ratio of an area of a range including an inward curve to an area of a range including an outward curve in a predetermined load-deflection characteristic.
