Sitting still is optional with this active-seating wobble stool that lets you rock, swivel, and tilt in every direction. The rounded base design engages core muscles while promoting proper posture, making it a favorite for classrooms, standing desks, and home offices. An octagonal silicone seat surface stays cool and comfortable, while the embossed rubber bottom grips floors securely. Height adjusts from 16.5 to 24 in to accommodate ages seven and up.
