Best in class
When Bill Stumpf and Don Chadwick designed the Aeron Chair (1994), they combined a deep knowledge of human-centered design with cutting-edge technology to create a chair unlike any other. In 2016, Don Chadwick evolved Aeron with decades of research in the science of sitting, as well as advancements in materials. The result is the perfect blend of ergonomics and comfort. Is it any wonder that more than 8 million Aeron Chairs have been sold worldwide?

Comfort in action
Every component of Aeron is designed to maintain proper alignment and balance – no matter the sitting position. The patented PostureFit SL hardware provides adjustable spinal support that helps your body mimic its strongest posture: standing, chest open, and pelvis tilted slightly forward. From upright and active to a deep recline, Aeron’s state-of-the-art Harmonic 2 tilt mechanism moves with you naturally and supports your entire range of movement. Fine-tune Aeron even further with its fully adjustable arms, seat height, and recline. And with the new Onyx colorway, you can experience the same comfort with more sustainability. Made with up to 2.5 pounds of recycled plastic, the production of Aeron in Onyx helps divert more than 44 metric tons of plastic from the ocean annually.*

Bill Stumpf

Bill Stumpf once said that he liked to collaborate with other designers the way a jazz trio improvises, playing together with no fixed destination. The approach requires complete attention, and you have to trust your instincts. Design should make room for spontaneity and discovery, said Stumpf, “blending the pleasure and pain of life into something wonderful.”

Don Chadwick

Chairs are for sitting on. It sounds obvious, but there are designers who seem to miss that point. Not Don Chadwick, however, who has developed some of the best chairs on the market – including the Aeron Chair with Bill Stumpf – by emphasizing the body and the fact that bodies move.
