Fantastically responsive stool that mimics the movements you can get from a large (and awkward) yoga ball. This stool is height adjustable and can pivot, rock and turn. Great for any type of desk or other work environment. In perfect shape -- no issues and like new. Seat height range is 20”-33”
Retails for $450 and UP – this is the "factory" version that has a cover over the pivot mechanism to keep it free from dust, etc.
