Provided is a vehicle seat capable of stably supporting buttocks of a seated occupant in an adaptive manner according to each right-to-left width of the seated occupant's body, which width is different from occupant to occupant, during a turn of a vehicle. The vehicle seat includes a seat cushion (2) having a seat surface (8) and configured to support buttocks of the seated occupant from below, and a right and left pair of side supports (9, 9) provided on right and left sides of the seat surface, which side supports bulge upward to be higher than the seat surface and allowed to laterally support the buttocks of the seated occupant from either side. Each of the right and left pair of side supports (9, 9) is movable individually in the right-to-left direction with respect to the seat surface. During a turn of the vehicle, one of the side supports on an outer side of the turn is moved inward so as to support the buttocks of the seated occupant from the outer side of the turn. When the turn of the vehicle is completed, the moved side support is returned to its original position.
