Its integrated lumbar support and padded armrests ensure maximum comfort and efficiency. 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" chrome base with 2" casters offers extra stability to the chair by spreading the load over a larger surface area to help prevent tipping. Executive chair supports up to 275 lb.
