This tunnel shaped pillow is designed for snuggling. It was created to prevent numbness and pain while snuggling in a spooning position. This pillow can also be used by a single side sleeper to prevent those annoying pins and needles in arms, wrists and hands. Makes a great gift! Inside each Coodle® pillow, is high quality foam surrounding four arched plastic braces. These braces inside each pillow serve to block pressure from pressing against an arm or a leg. Each pillow includes a removable cream colored cover.
