Varies sizes available for Gymnic Sit'n'Gym.

The Sit n Gym ball, which is designed for children and is used in the elementary schools, provides the same beneficial effects of correct posture maintenance as the classic physiotherapy ball. Thanks to its dynamic sitting, it fosters attention and concentration. Its small feet help avoiding the ball to roll in the surrounding area.
