How to Choose Your Chair, Adjust It, Care for It, and More
Designed by Bill Stumpf and Don Chadwick nearly 30 years ago, the Aeron Chair revolutionized office seating upon its launch in 1994. Stumpf and Chadwick were pioneers of ergonomics and material innovation: They didn’t rely on the ubiquitous foam and fabric materials common to the office furniture industry at the time. Instead, they developed breathable 8Z Pellicle® fabric and conducted extensive research to create a human-centered design on the cutting edge of technology.
In 2016, the Classic Aeron was remastered by Don Chadwick and in 2021, the Herman Miller® Aeron was made more sustainable with ocean-bound plastic. Since its inception, Aeron’s legacy of sustainability and innovation has continued to modernize the office landscape – and the Aeron office chair remains a benchmark for ergonomic seating.
Materials Make the Difference
There’s more than one reason to love the bestselling remastered Herman Miller Aeron office chair. It’s good for the body and good for the environment, too. Aeron comprises more than 50 percent recycled materials, and it’s now made with ocean-bound plastic, which diverts more than 150 metric tons of plastic from the ecosystem annually. Innovative 8Z Pellicle fabric also sets Aeron apart from the competition. This mesh-like material offers comfort through eight varied zones of tension in the seat and back. The tightest zones keep the body off the frame and in the chair, while more compliant zones conform to the sitting bones (the lower part of your pelvis) and distribute weight evenly. These zones eliminate circulation-restricting pressure points. Among the best Herman Miller mesh office chairs, Aeron’s 8Z Pellicle fabric allows air, body heat, and water vapor to pass through the seat and back, helping you maintain a comfortable, even temperature.
How to Adjust Your Aeron Chair
Wondering “How do I use my Herman Miller Aeron?” Follow these steps to adjust your Aeron for the most comfortable sit.
A paddle-shaped lever on the right side of the chair adjusts the seat height. To raise the seat, take your weight off the chair and lift the lever up. To lower the seat, lift the lever up while seated with your weight on the chair. Ensure your feet rest flat on the floor to maintain a healthful posture.
Adjustable Lumbar Support
An adjustable strap on the back of the chair controls the height of the Aeron lumbar support pad, which should be positioned to comfortably support the natural curve of your spine. Using equal pressure on each end of the support, raise or lower it to the desired position within the adjustment track.
Adjustable PostureFit SL
A knob on the back of the chair controls the PostureFit SL feature. To engage PostureFit SL, sit with your back against the seatback, then reach behind the chair and turn the knob forward until you find the support that feels right for you (it should support the natural alignment of your spine and provide lower back comfort). To disengage PostureFit SL, turn the knob backward while seated.
All Aerons feature a long stem with a knob – on the right side of the chair, below the seat – that controls the tilt tension, or the amount of resistance you feel when leaning back. To increase tension (i.e, feel more resistance when leaning back), turn the knob forward while seated. To decrease tension, turn the knob backward.
Tilt Limiter and Seat Angle
If you’ve opted for the Tilt Limiter and Seat Angle feature, you’ll find two knobs on the left side of the chair, below the seat. The inside knob can be rotated forward to limit the tilt range or backward to release the tilt limiter. When you want to sit in an upright or partially reclined position, the tilt limiter should be engaged.
The other of the two knobs controls the seat angle. To move the seat from a horizontal position to a 5-degree forward tilt, lean back and rotate the knob forward. To resume a horizontal position, lean back and rotate the knob back all the way.
A lever on the base of the arm support adjusts the arm height. Lift the lever to unlock it, then grasp the base of the arm support and raise or lower it to your desired height. Finally, lower the lever to lock the arm in place.
To adjust the arm angle, grasp the front end of the armpad and pivot it to the left or right. To adjust the arm depth, grasp the front end of the armpad and slide it forward or back.
How to Care for Your Chair
With regular care and maintenance, your Aeron will last for years to come. The base, frame, and armpads can easily be cleaned: Wash with a soft cloth soaked in mild detergent and warm water, rinse thoroughly, and dry with a soft cloth.
8Z Pellicle fabric should be vacuumed as needed using an upholstery attachment. Spot-clean stains with a soft, absorbent cloth. For additional details, check out our comprehensive Care and Maintenance Guide.
The Aeron Chair is covered by a 12-year warranty that includes parts and labor. It also covers the cost of service when warranty work is performed in the U.S. or Canada.
If your Aeron needs service, start by checking with the Herman Miller Dealer or Retailer where you purchased it to determine if it’s still under warranty and eligible for replacement or repair. If so, you’ll need to provide a clear picture of the manufacturing label (with complete product number, FO number, and manufacture date), as well as a description of the issue and a photograph identifying the issue.
