There is disclosed a cushion for absorbing energy to dampen vibration, distribute pressure and absorb shock. The cushion has a deformable polyurethane bladder which defines a chamber adapted to contain a fluid, such as air. A piece of viscoelastic material, such as a highly plasticized PVC gel, may be located inside the bladder so that when air is introduced into the chamber, the cushion is capable of absorbing energy to dampen low amplitude vibration, distribute pressure and absorb high amplitude shock. The cushion has a valve in fluid communication with the chamber for selectively varying the amount of air so that the shock absorbing capability of the cushion may be varied. Various embodiments incorporating the cushion are disclosed, including a removable bicycle saddle pad, a bicycle saddle, a wheelchair seat pad and a cyclist's glove.
