Unlike inversion tables, this patented, FDA approved apparatus gently relieves lower- and mid-back pain and stiffness without requiring you to be suspended upside down. 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 unit's shoulder pads keep your upper body properly aligned and an adjustable padded waistband lets you customize the device's range of motion. Using the apparatus for just 5-10 minutes a day can relieve back discomfort without medication. 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. yet it is lightweight and compact for convenient transport and storage. Assembles easily. 48" L x 30" W x 24" H. (23 lbs.)
