A 90 to 155 degree recline is what separates this from a plain task chair, and the lever locks the backrest at any point along that sweep. The back panel alone measures 21 by 36 inches, tall enough to carry the shoulders, with an 11 by 7.5 inch head pillow and a 12 by 8 inch lumbar pillow riding on straps. Seat area is 21 by 21.5 inches, lifting through 3 inches between 18.5 and 21.5 inches. Slide out the 14 by 8 inch footrest for a break, or use the 15 degree rocking function while the back stays upright. Linkage armrests move with the recline. Five anti-wear wheels and a 360 degree swivel handle mobility; the chair carries 330 lbs, stands 49 to 52 inches and weighs 44 lbs.
