The Modern Executive Conference Chair features CaressoftPlus upholstery to give you an ultra-soft seat that's both breathable and durable. This trademarked vinyl looks and feels like leather yet cleans easily with just a damp cloth. 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 offers extra stability to the chair by spreading the load over a larger surface area to help prevent tipping. Pneumatic gas lift allows easy seat-height adjustments to help you find the personalized sitting style that suits you and your work environment. Padded, stationary loop arms are ergonomically shaped for comfort and extended use. Hooded, double-wheel casters slide smoothly on floors to make it easy to move and shift directions. Executive chair supports up to 275 lb.
