Ergonomic to the core, Aeron was designed for a wide range of body types, thanks to the extensive research from designers Bill Stumpf and Don Chadwick nearly 30 years ago. Its launch was pioneering in the office furniture industry – and it still is, thanks to updated research and material innovation, including the addition of ocean-bound plastic to the body of the chair. We've always known Aeron is good for our bodies – now it’s just as good for our environment too. 

Aeron is available in a palette of four meticulously curated material expressions centred on elements pulled from the earth. Onyx is a dramatic ultra-black shade intended to modernise Aeron. Each component of the chair was thoughtfully designed, creating a fundamentally harmonious colour palette.

Aeron’s legacy of sustainability and innovation continues since its introduction nearly 30 years ago. It proved pioneering in both ergonomics and material innovation, without relying on the standard use of foam, fabric or leather found in most office chairs at the time. It’s also our first product to receive the industry-leading Cradle to Cradle V3 Silver Level certification. Aeron is composed of more than 50% recycled material – and now, we’ve added ocean-bound plastic, diverting more than 150 metric tons of plastic from the ecosystem every year.
