A vehicle seat has a scissor-type stand vibratable and adjustable in height, with a pneumatic spring and cranks, intersecting at a scissor shaft. A control device for level control and for height adjustment of the stand has a control element, a valve device controlled by the control element, for controlling the spring, a switching element movable relative to the control element or the valve device, and a bearing. The control element and valve device are kinematically assigned to different parts of the stand movable relative to one another. The control element is linked to a first crank. The bearing is spaced from the shaft and connected with a second crank. The valve device is connected with the switching element movable relative to the control element.
