Body Bumper and Roller helps tone and strengthen upper and lower body. Children can build their upper body strength by kneeling in front of the bumper and roll it back and forth to exercise arms and shoulders. Alternatively the bumper can be rolled using their feet to increase thigh and calf strength. The Body Roller provides deep pressure therapy as the child crawls between the rollers. The rolls are fully padded which helps the child to relax. The tension setting can easily be adjusted.
