A height adjustment device of a vehicle seat comprises a control valve means for governing the degree of filling of a compressed air actuator. Following an alteration in the weight to be carried by the compressed air actuator there is a relative switching over movement between a component bearing a control cam slide and a component bearing an actuating member entailing the switch over of the control valve means. The relative switching over movement is a linear movement, the two components bearing the slide and the actuating member being guided for relative sliding linear motion in the direction of the switch over movement. Furthermore a vehicle seat having such a height adjustment device is provided.
