Abstract: A stroller has a frame with at least two wheels and a seat unit for supporting a person sitting on it. The seat unit has a seat surface which is designed to be driven movable and/or wherein the seat surface has a plurality of driven movable partial surfaces. A movement pattern of the seat surface and/or the partial surfaces is predetermined in such a way that the back movement of a riding animal is simulated in at least one gait. The seat unit has a kinematic unit for predetermining the movement of the seat surface or the partial surfaces, which is arranged directly below the seat surface or directly below the partial surfaces. Alternatively or additionally, the stroller has a differential connected to at least two wheels so that a combined kinetic energy of these wheels is provided for the movement of the seat surface or the partial surfaces.

Abstract: A seating/lying support (7) includes at least two seating/lying support elements (7a, 7b, 7c, 7d) which are movably interconnected, and at least one bearing element (8.1, 8.2, 8.3, 8.4). The at least one bearing element (8.1, 8.2, 8.3, 8.4) is connected to the seating/lying support elements (7a, 7b, 7c, 7d) such that a movement of the seating/lying support elements (7a, 7b, 7c, 7d) relative to one another can be produced.
