The Gymnic Sit n Gym 18"
has little feet to prevent it from rolling away when used as a sitting ball chair. This type of ball is widely used in European kindergartens and classrooms as chairs and they've fast become a popular addition to classroom seating in the United States as well.

The Gymnic Sit n Gym encourages dynamic sitting. Gentle body movements improve blood circulation and increases the child's attention span which is conducive to better learning.
The Sit n Gym also promotes proper body alignment for better posture. Another great thing about the Sit n' Gym is you get twice the value - you can use it as a seat and as a regular exercise ball if you turn the little feet to the side. This Therapy Ball chair is made of super strong latex-free vinyl material and is surface washable.
