The ergonomic Quinn Mesh Back Task Stool features a black fabric seat with a black mesh back and black base. The backrest is made from a stretchy mesh material that moves in four directions to provide multidirectional lumbar support and is designed to cradle your spine. The contoured, high-density molded seat reduces pressure points and provides support for a variety of users. A synchro-tilt mechanism allows the back to recline at a 2-to-1 ration to the seat to maintain proper back alignment. This modern work stool has an adjustable footring that moves up and down, then locks in place to best suit users of varying heights. Other features include tilt-tension to control the rate and ease of recline, a height-adjustable and swivel seat and height and width-adjustable arm rests. A black plastic base with five casters offers mobility. Meets or exceeds ANSI/BIFMA standards. Supports up to 300 lbs.
