A pneumatic seat support (10) by itself supports a seat (16) above a floor of a vehicle. The pneumatic seat support (10) has upper and lower air chambers (14, 12). The lower air chamber (12) is a rigid cylindrical tube (30). The upper air chamber (14) is a flexible cylindrical bellows (34), with a diameter greater than the diameter of the tube (30). Three or more linear shafts (44) extending through the upper air chamber (14) and into the lower air chamber (12) provide a single-degree-of-freedom bearing support structure (42) that allows vertical motion of the seat (16) but withstands horizontal loads on the seat (16). When the seat (16) moves vertically downward, it compresses air in both chambers (12, 14), providing a seat support system with a natural oscillation frequency which is less than 2.4 Hz, and preferably in the range of 1.5-2.2 Hz.
