Abstract: An inflatable device can be used for physical therapy, conditioning or training. The device has a support platform and a flexible member. The flexible member is attached or affixed to, and has a bowl-shaped distention projecting from one side of, the platform. This flexible member is inflatable to a pressure for supporting a person. The device is inflated in order to support at least some of the weight of a person by compressing the inflatable device at or adjacent to its center. When the person wishes to later change the characteristics of the device, the pressure in the inflatable device can be changed to change its stability.
