Executive High-Back Chair is upholstered with LeatherPlus, a combination of leather and polyurethane, to promote exquisite softness and durability. Padded, fixed-loop arms are ergonomically designed for extreme comfort through extended use. Pneumatic gas lift allows easy seat-height adjustments to help you find the personalized sitting style that suits you and your work environment. Spring-tilt mechanism allows you to change the angle of the entire seat relative to the floor and to transfer some of your upper body weight to the backrest of the chair. The 27" nylon base offers extra stability to the chair by spreading the load over a larger surface area to help prevent tipping. Hooded, double-wheel casters slide smoothly on floors to make it easy to move and shift directions. It also includes integrated lumbar support, upright locking position, adjustable tilt tension control and more. Executive chair supports up to 275 lb.Executive High-Back Chair is upholstered with LeatherPlus, a combination of leather and polyurethane, to promote exquisite softness and durability.
