Uncaged Ergonomics Wobble Stool Air, Rolling Balance Ball Chair with Wheels, Adjustable Height, 19-25.5 in., 250 lb. Capacity

This rolling wobble stool brings balance-ball-style movement to a compact, height-adjustable seat that fits under a standard desk. An air-filled cushion beneath the fabric seat creates gentle, responsive movement that encourages active sitting and frequent position changes. Unzip the cover and add or release air to customize the firmness and wobble level for your comfort and work style. The seat adjusts from 19-25.5 in. for standard desks, home offices, classrooms, craft rooms, studios, and shared work areas. Five rolling casters make it easy to move between tasks, while the 360-degree swivel helps you reach tools, supplies, files, or nearby work surfaces without repeatedly repositioning the stool. A 15.25 in. seat and approximately 15 in. base provide comfortable support in a space-saving footprint, and durable construction supports up to 250 lb. Best suited for standard desks when you want active movement plus the convenience of rolling between tasks. This compact balance chair offers much of the movement associated with an exercise ball chair without the size or uncontrolled rolling of a large ball. Designed for indoor, dry workspaces. Uncaged Ergonomics has designed and supported ergonomic workplace products since 2010.
