Many schools use the Wiggle Cushion to help students while sitting at their tables and/or desks. We purchased one to use while sitting at the counter. Our child had difficulty sitting and would tip the chair over and/or stand while eating. The Wiggle Cushion really helps her sit still and finish a meal. You can adjust the amount of air you want in the cushion and it has a smooth side and bumpy side for kids to sit on.
