Blue physio roll, diameter 30cm, length 50cm. For correct size measure from your child's armpit to the tip of the middle finger in centimetres, this will give you an idea of the best roll height for your child. Additional Information Physio rolls are easier to use than traditional gym balls as most of the movement is limited to forward and back, providing greater stability than a round ball. Also the saddle shape makes it easy to straddle, sit on or roll over. Designed to improve balance, gross motor skills and core strength, can also be beneficial for those with attention or movement needs.
