Move around with a chair that moves right along with you. Arillus conforms to your every move with a waterfall seat of suspended mesh weave that supersedes the need for stuffy foam padding.

Complete with height adjustable vinyl padded armrests, tension control knob, a tilt mechanism that enables you to lock the chair in any position, and a powerful pneumatic lift for height adjustment, and the result is one tour-de-force of excellence. Topped off with a dual-tone nylon base with five hooded dual-wheel casters, and you have a comfort and posture perfect chair for any home or office.
