Designed by a chiropractor, this natural back support system uses your body's own weight to apply controlled pressure to the spinal vertebrae. As you lie on Spine-Worx, your spine is pressed firmly against the length of its two unique padded and contoured rails, injection-molded to fit the natural shape of the mid- and lower back. The vertebrae in the spine are gradually and gently encouraged to realign into their natural positions, which helps to relieve backpain and improve overall mobility.
