ABSTRACT:
A generally triangular bolster of rigid material provides firm support for persons wishing to recline or lounge upon a surface, while at the same time providing the comfort desired due to its specific structure. The bolster includes three sides which may be equilateral, with each of the sides preferably including an inward or concave curvature. The curvature not only provides additional comfort for the user, but also results in relatively sharp apex edges. The apex edges thus tend to penetrate a compliant surface, such as carpeting, grass, or sand, and thereby prevent the lateral displacement of the bolster when a person reclines upon it. The bolster may be formed of a variety of materials, such as plywood or other wood sheet, or molded or extruded from plastic. Handles near each apex edge provide easier portability, and the bolster may further include internal bracing which also provides storage shelf space within. The exterior sides may be covered with a variety of materials for greater comfort, such as carpeting for indoor use, or with a padded vinyl for outdoor use.
