These durable, inflatable spaces are made with super-strong vinyl and tough triple-welded seams for added strength. Most children can get into the PeaPod themselves, applying deep, even pressure to many sensitive areas of the body. Some children like to gently rock side-to-side for that perfect “cocooning-calm”. The velvety “pod” surface is made with comfortable flocked vinyl that is surface washable. Valves make it easy to inflate and deflate.
