Abstract: A user device (100) is provided. The user device is a footwear device (100a), a medical device (100b), a mattress device (100c), or a seat cushion (100d), and is shaped to define a plurality of chambers (28). Apparatus for use with the user device includes circuitry (34, 152) and a pump (38, 130). The circuitry includes at least one device pressure sensor (36) that measures pressure in the chambers. The pump is couplable to the user device by a user 18, and the circuitry actuates the pump to selectively inflate or deflate the plurality of chambers to at least two different respective pressures. The pump is decouplable from the user device without the decoupling affecting the respective pressures in the chambers. Other applications are also described.
