Designers Bill Stumpf and Don Chadwick kept innovation at the core of the Aeron Chair from Herman Miller. Its revolutionary ergonomic support, breathable comfort, and adjustable arms, seat height, depth, and recline make it effortless for everyone to benefit from an optimal seating posture. Aeron's 8Z Pellicle suspension material features eight separate zones of tension to quietly support your body's pressure points for all-day ergonomic support and comfort. Its three sizes—A, B, and C—were precisely designed to welcome a wide range of body types, from the first to the 99th percentile. Made in part from recycled ocean-bound plastic, it's an eco-friendly choice, too.
