This rolling office furniture provides work space and seating where you need it, and tucks out of the way when you're through. They can be used together as a standing desk and stool (a style increasingly being adopted by active executives who want a change of position during the workday), but each can play a role in your office separately: The table can provide a large mobile workspace that can be repositioned throughout the day, while the backless stool can roll out from under a desk to provide instant seating for an impromptu meeting. Desk and stool have locking wheels for stability. Any-Height Stool.

Seat range is 21 1/2" to 31 1/2", with a 22" nylon-coated cast aluminum base. Seat is 19" W x 16" D. No premium or express delivery offered on this item.
