With high-density seat foam and a generously scaled back, Quotient comfortably supports a wider range of users. Mesh mid-back task chair features a seat cushion that contours reduce pressure points to provide support exactly where needed. The ilira-stretch mesh knit fabric back cradles spine. Additional support bar on back frame increases overall strength. Controls on this chair are easy to reach and simple to understand, featuring only one lever and front-access tilt tension. Synchro-tilt mechanism reclines the back at a higher ratio than the seat for proper back alignment. Arms adjust from 7-4/11" to 11-4/11" in height and 17-3/8" to 20-1/8" in width. Other functions include pneumatic seat-height adjustment, 360-degree swivel and tilt lock. 26-1/2" diameter, five-star base is equipped with 2-4/11" dual-wheeled casters for easy chair movement.
