Zoned contouring divides the 21.5 by 26.5 inch backrest into separate regions, so shoulder blades and lumbar curve each meet padding shaped for them rather than one flat slab. The seat spreads 21.5 by 20 inches and carries a thick sponge core under PU and PVC leather that wipes down in seconds. Padded armrests stand 27.5 to 31 inches above the floor, close to standard desk height, and the backrest locks anywhere between 90 and 105 degrees. Seat height travels from 19.5 to 23 inches. A five-claw metal base with casters supports 330 lbs and rolls without catching on rugs. Assembled the chair occupies 28 by 30 inches of floor, reaches 46.5 inches at the headrest and weighs 35.5 lbs.
