This is the heated massaging leg rest that promotes correct spinal alignment to help soothe pain caused by sciatica, arthritis, and other back and leg conditions. Offering firm support with a soft velour cover, the bolster elevates the knees and mitigates pelvic tilting to help ease pain caused by strain on the spine. Meanwhile, the comfortable heat warms the hamstrings, backs of the knees, and calves to promote blood flow, and four vibrating massage heads, at two intensity levels, knead out any knots. The wide cushion supports both legs at once, and the heat and massage settings can be enjoyed simultaneously or separately. With a removable cover and auto shut-off after 15 minutes. Gray. Plugs into AC. 24" L x 12" W x 12" D. (6 lbs.)
