In 2016, we remastered Aeron from the casters up, making it lighter and incorporating technological and ergonomic enhancements, including a more refined tilt mechanism for a smoother recline, adjustable PostureFit SL for better spine alignment, and 8Z Pellicle suspension for better comfort and pressure distribution. Our refurbished Aeron Chairs are restored from pre-owned chairs to meet Herman Miller quality standards and are covered by our 5-year refurbished product warranty. Some cosmetic wear from prior use may be visible.
