Imitation lamb fleece covers a U-shaped cushion that runs 25 by 21.5 inches and 3.5 inches thick, giving both legs somewhere to sit when you tuck them up instead of dangling them off a narrow pad. The backrest is unusually broad at 23.5 by 15 inches, spreading contact across the whole back rather than a single lumbar point. Height adjusts between 30.5 and 35.5 inches overall, with the seat itself moving from 19 to 24 inches, and a tension knob opens a 100 to 120 degree rocking range. A 28 inch diameter heavy-duty base anchors the chair and carries 350 lbs. Full dimensions are 26 by 25 inches, and the chair weighs 30 lbs. The fleece surface brushes clean with a soft cloth, and the wide base spreads the load rather than concentrating it on a narrow column. The imitation lamb fleece upholstery gives this wide criss cross chair a softer look than a standard task chair. Seat height: 19" - 24"
