The seat (1) has a roller guide comprising a partly lateral open guide rail. A roll shell of a roller comprises a tread along a roll lower-side inner wall of the guide rail. The inner wall is arranged parallel or at an angle to a longitudinal extension of an axle. The roll shell is made of an elastic material deformable by seat occupancy by applying pressure. The roll shell is applied in a quiescent condition without the seat occupancy in the roll lower-side inner wall of the guide rail. Lower part (5) of the seat is connected with upper part (6) of the seat through scissor arms (7). |
