This is the stretching aid that supports the spine’s natural curvature to help relieve back pain. Its 15 ABS molded ribs each form two raised nodes that align with the muscles of the mid and lower back without placing any direct pressure on the spine itself. One’s own body weight presses the nodes against the back, relieving fatigued muscles. Its curved shape realigns the spine back to its natural shape, countering the effects of slouching. Assembly required. For users up to 222 lbs. 22 1/2" L x 9 2/3" W x 3" H. (3 lbs.)
