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 20 years’ research in the science of sitting, as well as advancements in materials. The result is the perfect blend of ergonomics and comfort. The Aeron Stool brings all these innovations to a height-adjustable ergonomic stool that’s the ideal partner for sit-to-stand desks, drafting tables, and a more active, dynamic workspace. 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).
