Task chair features a breathable mesh back and a spacious cushioned seat that is upholstered with fabric. Responsive elastic mesh forms a translucent, patterned, weave back for a contoured, supportive back. Thin, ultra-comfortable pillow top foam allows better blood circulation, reducing seating pressure points. Functions include swivel tilt with pre-set tension and pneumatic gas seat-height adjustment. Arms also adjust in height so you can find a better positioning. Five-star base is equipped with 2" casters so you can easily slide your chair where you need it. Weight capacity is 300 lb.
