Designers: Bill Stumpf and Don Chadwick. Its the most well-known ergonomic office chair ever made. With good reason. As the first to replace fabric and foam with a breathable, woven suspension membrane—its innovative Pellicle seat and back—Aeron distributes your weight evenly, eliminating pressure points and heat buildup. The Kinemat tilt lets you recline fluidly, and PostureFit puts support where you need it most while seated—at the base of your spine.
