The invention relates to a device for the pneumatic adjustment of a seat in a means of transport, in particular in a motor vehicle, comprising one or more cushions (3) which can be filled with air and which are connected via one or more valves (1) to a compressed-air supply (2), and a control device for the actuation of the one or more valves (1) for the purposes of changing the filling state of the one or more cushions (3). The device according to the invention is characterized in that a respective valve (1) of at least some of the valves (1) comprises one or more actuation elements (4) composed of electroactive polymer, to which an electrical voltage can be applied. By application of the electrical voltage, a respective actuation element (4) is deformed, and in this way, one or more passage openings (6, 6′) via which an exchange of compressed air with at least one cushion (3) takes place is or are opened up or shut off.
