Details: This tunnel shaped pillow is designed to prevent pressure and numbness of limbs while cuddling. Inside each pillow are four arched plastic braces. These braces serve to block pressure from pressing against an arm or leg. Superior quality US made specialty suspension foam. This suspension foam cradles and softly suspends head above arm. For over twenty years, the inventor of the Coodle Pillow has experimented diligently to provide the best possible problem solving pillow. The function of the Coodle is centered around our original US patent and has been improved upon over the years. We are very proud of our foam technology. Can be used solo or with a partner.
