Quilted leathaire covers a back that stands 26 by 19.5 inches and splits into separate zones for the neck, shoulders and lumbar curve, so support arrives where the spine actually needs it. The seat cushion is 4 inches thick over high-density sponge that resists flattening, and the padded armrests keep the shoulders from creeping upward. Leathaire behaves like leather under the hand but takes far less upkeep, and the stitched surface hides everyday marks. A lever under the seat delivers 4 inches of height travel across a 19 to 23 inch range, while the tension control opens a 90 to 105 degree rocking arc. The metal base rolls quietly and is rated to 350 lbs. Full dimensions are 26 by 25 inches with a top height of 47 inches, at 27 lbs.
