A resilient air compressible apparatus with a resilient member formed from a hollow cylinder having a rigid disk disposed in the interior of the cylinder at each end, a second rigid disk disposed at the exterior of the cylinder at each end, and a portion of the resilient member interposed between the pairs of rigid disks. The resilient member is formed from multiple layers of resilient material, such as rubber and reinforced rubber. A bonding agent is used to bond the resilient member to the rigid disks. Compressed air enters the interior of the resilient member through an inlet member. The apparatus can be used to as a lifting device by utilizing bottom and top lifting surface members. For safety and control purposes, the lifting device can include a control valve that does not allow the user to over-inflate the lifting device.
