Abstract: In a vehicle seat, a movable frame provided at a front end portion of a stationary frame is configured to be slidable frontward and rearward between a first position and a second position frontward of the first position. An outer covering provided to extend frontward from an upper side of the stationary frame is configured to wrap around a front end portion of the movable frame. First and second straps are provided to extend rearward from a front end of the outer covering and configured to pull the front end of the outer covering rearward. The front end of the outer covering from which the first and second straps extend is arranged under the stationary frame. The first strap and the second strap are in positions spaced out laterally from each other. The first strap and the second strap are being pulled laterally inward.
