Abstract
A bolster has an axial compressibility profile chosen so that lumbar pain can be relieved when the user places the bolster under his or her spine and rolls from a softer portion of the bolster to a firmer portion of it. A preferred bolster comprises a tubular outer portion formed from a resilient closed-cell polymeric foam material such as polyurethane. This outer tubular portion serves to cushion the user and prevent discomfort. The bolster has a relatively rigid portion at one or both ends, and a transition portion between the rigid end and a softer portion some distance from the end.
