Uncaged Ergonomics Active Task Chair, Armless Office Balance Chair with Casters, Adjustable Seat Height, 19.5-25.5 in., 250 lb.

This armless office balance chair combines the familiar support of a task chair with subtle 360-degree movement hidden beneath the seat. The responsive balance mechanism creates gentle micro-movement that encourages active sitting and frequent position changes without making the chair look or feel like exercise equipment. An integrated backrest and supportive foam seat provide the familiar comfort of an office chair, while the armless design lets you sit closer to the desk and gives your upper body more freedom to move. The seat adjusts from 19.5-25.5 in. for standard desks, higher work surfaces, classrooms, studios, home offices, and shared workspaces. A 360-degree swivel and rolling casters help you turn and move between tasks, files, tools, and nearby work areas. The 16 x 18.5 in. seat is upholstered in easy-care polyurethane leather, and the compact approximately 18.5 in. base fits smaller work areas. Durable construction supports up to 250 lb. Best suited for customers who want active movement without giving up a backrest or the familiar feel of an office chair. Designed for indoor, dry workspaces. Uncaged Ergonomics has designed and supported ergonomic workplace products since 2010. We stand behind this chair with responsive customer service, available replacement parts, and a 1-year limited warranty.Color and Upholstery: Black polyurethane leather seat with foam cushioning.
