The Modern Executive Conference Chair features CaressoftPlus upholstery to give you an ultra-soft seat that's both breathable & durable. This trademarked vinyl looks & 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 & 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 & your work environment. Padded, stationary loop arms are ergonomically shaped for comfort & extended use. Hooded, double-wheel casters slide smoothly on floors to make it easy to move & shift directions. Executive chair supports up to 275 lb.
