This leather office chair's heated lumbar cushion soothes tense muscles and improves circulation for superior comfort while seated. Heating elements woven from carbon fibers line the lumbar support cushion and deliver deep penetrating heat to your back. The heating elements are powered by a rechargeable battery, ensuring a cord does not restrict chair movements, and they adjust to two different temperatures. The chair's backrest and seat are made from supple full-grain leather that is aniline dyed, a process that enriches the color and patina of the hide and allows minor scrapes to be rubbed out easily. The ergonomic chair has a height-adjustable lumbar support that encourages proper posture. The chair tilts, reclines, and locks into place at any position, and height- and width adjustable armrests and a height-adjustable seat accommodate any size user. Memory foam inside the seat and armrests cradles your body and relieves pressure points, and the subtly perforated leather backrest facilitates proper breathability. Five casters provide smooth mobility. Provides up to six hours of heat after a one-hour charge. Black or Brown. 41-43 3/4" H x 21 1/4" W x 20-24" D. (45 lbs.)
