This apparatus provides gentle but firm traction to relieve lower- and mid-back pain and stiffness. As you lean forward in the fabric hammock from a kneeling position, the device uses your body weight to create a strong, steady traction that relieves pressure on the spine and helps loosen tense back muscles. The side shoulder pads keep your spine, shoulders, and hips properly aligned and an adjustable padded waistband lets you customize the device’s range of motion. In clinical trials at The University of Western Australia, the device helped reduce patients’ back pain and stiffness while improving their quality of life and mobility after only three weeks of use. The unit’s 1" tubular steel frame supports up to 350 lbs. Includes chest and hip pads. Assembly required. 41" L x 24" W x 17" D. (23 lbs.)
