Originally designed by Bill Stumpf and Don Chadwick in 1994 and updated by Don Chadwick 2016, the Aeron Chair has become the gold standard in blending ergonomics with comfort. 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 since it’s now composed of more than 50% recycled materials, you can experience the same comfort with more sustainability. Aeron is up to 91% recyclable based on available recycling facilities. Aeron is composed of more than 50% recycled material, including ocean-bound plastic. Aeron is BIFMA Level 3 certified and has also received the Indoor Advantage Gold certification, SCS Global Services' highest level of indoor air quality performance for furniture. The certification ensures that furniture products support a healthy indoor environment by meeting strict chemical emission limits for volatile organic compounds (VOCs).
