An apparatus is configured to support at least a portion of a body thereon. The apparatus includes a cover (62) having an interior region, a base (10, 50, 70, 124, 230) located within the interior region, and a three dimensional engineered material (60, 76, 106) located within the interior region above the base (10, 50, 70, 124, 230). The three dimensional engineered material (60, 76, 106) and the base (10, 50, 70, 124, 230) cooperate to provide support for the body. <IMAGE> |
