This is the height-adjustable workstation that lets you sit or stand while working, then folds away for unobtrusive storage. Unlike sitting in a rigid or uncomfortable chair for eight hours or more a day—standing while working helps reduce backpain while increasing mood, energy levels, and circulation. The desk deploys easily without tools by simply spreading apart its frame and flipping the hinged top from a vertical to a horizontal position. Once secured, the desktop adjusts to eight different heights from 32" to 49". It has a 36" x 21" surface, bottom shelf for storage, and four locking casters. With a steel frame and a natural wood top. No assembly required. Unfolded 36" W x 20" D x 32-49" H, folded 4 1/2" W x 20" D x 36" H. (40 lbs.)
