Padded task chair is ideal for computer labs, teacher chairs or office settings. Polyurethane padding on the seat and back delivers extra comfort for long work days. The 5/8" thick padding is covered with fabric that matches the seat color for a professional look and is bonded to the shell. One-piece, molded polypropylene shell offers the classic classroom look, but is enhanced with versatile frame. The gas-filled, pneumatic cylinder allows a seat adjustment range from 18-1/4" to 22-5/8" high. Armless task chair swivels 360 degrees and rolls on 2" diameter, dual-wheel, hooded, swivel casters on the five-star base.
