Helps calm and focus those in early primary school and preschool who have a hard time sitting still. It allows children to quietly move while working, enabling them to stay on task and be more productive. Flexible nubs on one side and smaller bumps on the other give a choice for just the right amount of tactile stimulation. Firmness can be customized with the easy-inflation pump (included). Effective on chairs, benches, or directly on floors.
