The present application relates to a vehicle seat (1) comprising a seat surface (2) and at least one rest part (3.1, 3.2) at an angle to the seat surface (2). The angle between the seat surface (2) and the at least one rest part (3.1, 3.2) is movable via an adjusting device (6, 13) between a first position, in which the at least one rest part (3.1, 3.2) is substantially at right angles to the seat surface (2), and a second position, in which the seat surface (2) and the at least one rest part (3.1, 3.2) form a substantially flat surface. A second end (10.1, 10.2) of the at least one rest part (3.1, 3.2) comprises at least one pneumatic cushion (4) which is fluidically connected to a pump (7), wherein a control device is configured such that the pneumatic cushion (4) is substantially completely emptied when the at least one rest part (3.1, 3.2) moves from the first position into the second position.
