Pocket springs sit inside the back cushion, an unusual choice for a desk chair, and they push back with more bounce than foam alone. Over them go PU leather and high-density sponge, with a separate lumbar pillow measuring 16.5 by 10 by 4 inches for the small of the back. The seat cushion is 5 inches thick at 21.5 by 19 inches. Recline anywhere from 90 to 135 degrees, slide out the 13 by 8 inch footrest, and the chair stretches to 59 inches long for a midday break. Height adjusts through 3 inches across an 18 to 21 inch seat range, and the swivel turns 360 degrees. Rated to 400 lbs, the chair measures 29 by 27.5 inches, stands 45 to 48 inches and weighs 43 lbs.
