The bodyCushion is a high-tech, high-quality body positioning system that allows a person to lie in any position without unnecessary pressure on soft tissue areas. Supporting the body on its bony structures - clavicles, ribs, sternum, pelvis - enables the body's soft structural components to relax, deeply. The bodyCushion is unmatched in enabling this effect. When the body is relaxed, all types of therapy are easier and more effective. This is the 4-piece set which includes the Face, Chest, and Pelvic, and Leg Supports. All pieces are connected with Velcro® straps. This system comes with printed instructions.
