The unique design of Tumzee enables babies to be propped up on their stomachs, 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 incline they are able to see the surrounding environment and play with toys developing neck, back and arm muscles as well fine motor skills. Tumzee has the softness required for infants to be comfortable laying on it but the stiffness necessary to support their weight. Tumzee is now used and recommended by doctors, chiropractors and therapists.
