The Portable Back Hammock with Heat and Ice Therapy helps prevent and alleviate back pain naturally. It comfortably supports your upright seated posture, delivering extra healing power and pain relief, thanks in part to its ice and heat packs. Simply wrap the unit around your body, hook the knee pads over your knees and pull on the adjustable straps to perfectly align your spine. It’s lightweight and portable, so you can take advantage of its supportive benefits in any chair you choose. The best part: wearing it just 15 minutes a day provides serious relief!
