Designed with a gently rounded bottom, Wobble Chair transforms the boring conventional seat into a playground for your child's imagination. Regular chairs force children's bodies to conform to an unnatural posture. The innovative Wobble Chair allows your knees, hips and back to find comfortable and ever-changing positions. Homework, drawing, eating and playing video/board games are no longer sedentary activities. Colorful choices make it a good fit for any child's room.
