How does Neck Rest work? Neck Rest is intended to help your neck and shoulder muscles relax by temporarily supporting the weight of your head. Neck Rest incorporates an innovative flex-tension response that acts like a built-in spring to provide proper support for your head. This unique feature also allows Neck Rest to conform to the shape of your neck for a comfortable fit. Made of polyurethane foam covered with nylon/spandex, Neck Rest is durable and lightweight, making it easy to carry and pack.
