Vehicle seat, having - a seat part for seating a user of the vehicle seat, - at least one seat base for mounting the vehicle seat on a vehicle floor, - a height-adjustable connecting frame which connects the seat part to the seat base mechanically, so that the seat part can be moved in the vertical direction with respect to the seat base, wherein at least one setting device for fully automatically setting and/or limiting a seat height of the seat part during a seat loading of the seat part by the user, the setting device comprising at least one adjustable actuating means which by itself actuates a setting mechanism of the setting device as soon as the seat height, as a result of the seat loading of the seat part, undershoots or exceeds a height limit value which is predefined by the actuating means, so that the seat height is fully automatically shifted back to the height limit value, in particular in a self-regulating manner, by the setting device depending on the degree of seat loading of the seat part, wherein the setting device has - at least one valve element for aerating or deaerating a fluidic height adjustment device for setting, in particular for lowering, a vertical spacing between the seat part and the seat base, and - at least one switch element for actuating a fluid pump for increasing the vertical spacing between the seat part and the seat base, the actuating means actuating the valve element when the height limit value is exceeded, and the actuating means actuating the switch element when a height limit value is undershot, characterized in that a lever element, comprising three lever struts (210A, 210B, 210C) which protrude away from the rotational axis in a star-shaped manner, of the actuating means is mounted on the seat base or on the seat part, in a rotationally movable manner about the rotational axis which extends perpendicularly with respect to the vertical direction, so that the lever element of the actuating element is rotated about the said rotational axis by a vertical movement of the seat part relative to the seat base, so that, in a first rotational position of the lever element, a first lever strut actuates the valve element, and, in a second rotational position of a second lever strut, the said lever element actuates the switch element, wherein the actuating element has a height setting element which is fastened to a third lever strut. -
