Abstract: A stretching and exercising device is beneficial for torso flexibility, having a configurable structure in which the curvature of the platform is adjustable. The platform can be varied in curvature from a substantially flat configuration to a generally semi-circular configuration. The platform is supported by a gear train connected to the platform, wherein the platform has a plurality of discrete parts. An adjustment member having a manually adjustable variable length connects opposite ends of the gear train, so that the curvature of the platform is determined by the adjusted length of the adjustment member.

Abstract: An apparatus for relieving back stress composed of a body support cushion which is attached on its bottom surface to a rigid base member. The body support cushion supports the torso of a user. Attached to the rigid base member is an elevated restraint cushion which is positioned over the rear of, or behind the body cushion. The body support cushion, along with a force exerted by the restraint cushion on the thighs and pelvis of the user, allows for the immobilization of the lumbar spine in a state of flexion or extension. In addition to relieving back stress, the device can be used to perform various exercises.
