The Sit-to-Stand Active Stool from Norwood Commercial Furniture keeps you moving through long periods of sitting. The pivoting, padded, saddle-style seat encourages twisting, rocking and swiveling, engaging core muscle groups to reduce fatigue and keep users focused while they work. A sturdy flat base keeps the stool stable, providing ergonomic support as users change positions. This stool offers a height adjustable frame so it works with both sitting- and standing-height desks and tables.
