Two upwardly extending elongated ridge members are joined together in a substantially parallel and alined position. Each ridge member has a first end and a second end and an upper surface. The upper surface of each ridge member forms a convex curve substantially at the first end thereof that substantially corresponds to the natural lumbar curve of a human spine, forms a concave curve intermediate the first and second ends thereof that substantially corresponds to the natural thoracic curve of a human spine, and forms a convex curve substantially at the second end thereof that is slightly less than the normal cervical curve of a human spine. | |
