Tumzee has been designed for babies, from birth to crawling age. The unique design enables babies to be propped up on their stomachs on an incline, which helps reduce the frustration babies incur during this learning experience. It has a "t" support and contoured walls which will keep them from sliding down and will keep them in place. Because Tumzee is on an include, babies are able to see their surrounding environments and play with toys while developing neck, back and arm muscles as well as fine motor skills. Tumzee is now used and recommended by doctors, chiropractors and therapists.
