Our inflatable ball seats allow students to move and balance—reducing restlessness and improving focus while they learn! Made with sturdy, easy-clean PVC that’s lightweight enough for kids to move around the class, the seats each include 5 legs to keep them in place right where you want them. Seats require inflation and work great with our Automatic Ball Inflator (sold separately). Available in blue or green and two sizes: 17" and 22".
