A patient support includes a layer of fluid pressurized bladders, the bladders each having a chamber and an upwardly facing surface for facing and supporting a patient, and a cover over the layer of fluid pressurized bladders. Respective bladders in at least a group of the bladders each have a resilient body in its respective chamber to reform the shape of the respective bladder when a compression load on the respective bladder is removed wherein the pressure in the respective bladders is generally maintained without a powered supply of air. The cover has an upwardly facing patient surface and a bladder layer facing surface, with the patient surface for forming a patient support surface on the support, and the bladder layer facing surface for lying on the upwardly facing surfaces of the bladders. |
