Praised by doctors for its simplicity and effectiveness, this is the patented two-piece massage device that uses your bodyweight to help correct your posture and reduce or eliminate back, neck, and shoulder pain. Unlike harnesses that must be worn for hours, or electric massagers that only treat the symptoms of back pain and not the underlying causes, this simple device provides lasting relief with gentle 15-20 minute daily treatments. Users simply lie on the floor, with the triangular piece on the coccyx and the cradle under the neck. Silicone nodes at varying heights on each piece press against your body, creating a relaxing stretch and decompressing tissue to help realign your spine to its natural curvature. The compact, battery-free device can be packed along for a rejuvenating treatment anywhere.
