Designers Bill Stumpf and Don Chadwick kept innovation at the core of the Aeron Stool 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 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 while working on higher work surfaces and tabletops. The footrest platform is three times wider than the typical footring and was designed to provide a comfortable area to support your feet that also moves when you adjust your seat. Made in part from recycled ocean-bound plastic, it's an eco-friendly choice, too.
