<p>An inflatable cushion formed from a polygonal material blank (20) including a central body portion (24) and two foldable side panel structures (32,34) disposed laterally of a first body panel section (36) of the central body portion (24). The material blank (20) may be folded in loop fashion such that the central body portion (24) edges mate with the edges of the side panel structures (32,34) thereby permitting the formation of a poly sectional cushion including a mouth or other entrance means for introduction of an inflating medium and a body portion for holding the inflating medium.</p> |
