Combining distinctive looks with pioneering ergonomics, Aeron performs like no other chair. It adapts naturally and adjusts precisely to fit people of all sizes and postures doing all kinds of activities, all day long. The imaginative design of the work chair gives superior comfort, body support, and style that are widely copied but never matched.  In addition, it's the most well-known ergonomic office chair ever made. With good reason. The first to replace upholstery with the breathable, form-fitting Pellicle suspension that adapts to virtually every body and keeps you cool and focused.
