The Aeron® Office Chair is possibly the world's most admired and recognized ergonomic office chair. Its innovative design and support for a range of postures, activities, and body types, has made and kept Aeron an icon. Aeron office chair revolutionized office seating with its defining design qualities: the pioneering Pellicle suspension material and its patented PostureFit SL back support, which affords the ideal sit — chest open, shoulders back, pelvis tilted slightly forward. Combining a deep knowledge of human-centered design with cutting-edge technology, the classic Aeron chair is engineered with state-of-the-art adjustability, from the arms, seat height, depth, and recline, to help you maintain the optimal seating posture so you can focus on the task at hand. And it comes available in three ergonomic chair sizes, offering the most comfort to the largest range of users.

Product Highlights

• Adjustable PostureFit SL pads provide lumbar support and stabilize the base of the spine.
• Fully adjustable arms (height, depth, and angle) allow for a custom fit.
• Harmonic Tilt supports the way you naturally move, for a smooth and balanced recline.
• Breathable fabric keeps you cool and comfortable.

Dimensions & Measurements

Aeron Sizing Chart

To meet the needs of the widest range of body types, the original Herman Miller Aeron was designed in three proportional sizes. This approach to inclusiveness became an integral element of Aeron’s DNA. That’s why the new Aeron Chair is available in the same, body-fitting A-B-C sizing.

Use the chart below to help you decide which size of Aeron is right for your body. Height and weight are used here as key indicators of suitable chair-size choice. The most common size is B. If you have questions about which size is best for your needs, our product specialists can help, call us at 877.696.3342.

One Size Does Not Fit All

With chairs, one size does not fit all people. Based on an end-to-the-middle design approach, Aeron comes in three sizes (A,B, and C) to provide an inclusive fit that delivers the same level of comfort to the largest range of body types of any office chair. 

• A–Small Chair Size
  Recommended if you are:
  Height: 4’10" - 5’4” tall
  Weight: 90 - 150 lb
• B–Medium Chair Size
  Recommended if you are:
  Height: 5’2” - 6’6” tall
  Weight: 130 - 325 lb
• C–Large Chair Size
  Recommended if you are:
  Height: 5’3” - 6’6” tall
  Weight: 180 - 350 lb

Key Features

Even Pressure Distribution for Comfort

Pellicle , the innovative, elastomeric suspension of the original Aeron, eliminated circulation-restricting pressure points and stretched the boundaries of material design. New 8Z Pellicle™ pushes the material to a whole new zone—eight of them.

Exceptional Breathability

By doing away with foam and fabric, Aeron solved one of biggest prolonged sitting predicaments: the buildup of heat and humidity close to the body. Pellicle mesh allows air, body heat, and water vapor to pass through the seat and backrest to help maintain even and comfortable skin temperatures.

Superior Posture

If an active body is at its strongest when standing, chest open and pelvis tilted slightly forward, it makes sense that you would be better off sitting like that too. And that’s exactly where PostureFit SL™ comes in. Adjustable, individual pads stabilize the sacrum and support the lumbar region of the spine to mimic that healthful standing position.

Natural Ergonomic Movement

Staying in one position reduces the natural pumping action of the muscles that delivers nutrients to the intervertebral disks. The Aeron chair’s tilt allows it to move with the body in such a natural way that people can shift from forward to reclining postures without even thinking about it. Today’s slimmer, updated tilt mechanism delivers a more seamless experience of movement (and stasis) to the sitter through a smoother trajectory and optimal balance point.

Balanced Recline

Aeron lets you shift from forward to reclining postures without a thought. A slimmer, updated tilt mechanism delivers a seamless experience of movement and balance. Through a smoother trajectory and optimal balance point, it keeps people in contact with the seat back and in control of their movement throughout the entire range of recline.

Customized Design and Fit with Less Dial Turns

The original design made it possible to adjust the amount of recline and resistance to the sitter’s liking. Depending on the sitter’s scale, this involved up to 50 turns of the tilt mechanism. Advancements in materials and engineering allowed Herman Miller to scale back the amount of turning, twisting, and time spent customizing a personal fit. Now the sitter can reach a custom recline in 13 turns or less.

Eco-Friendly

Awarded the industry-leading Cradle to Cradle V3 Silver Level certification, assessed on our environmental and social performance, Aeron is up to 91% recyclable based on available recycling facilities. Aeron 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). 

Tilt Mechanism Options

Standard Tilt (Standard)

Standard Tilt comes with a tilt tension knob that allows you to adjust the amount of effort needed to recline comfortably while feeling balanced and supported. It does not have a tilt limiter mechanism.

Tilt Limiter with Seat Angle Adjustment (Optional)

Tilt Limiter lets you limit the recline range between fully upright and fully reclined. The tension control lets you adjust the amount of effort needed to recline comfortably while feeling balanced and supported. Recline range can be limited at one of three postures: upright, mid-recline, or full-recline.

Back Support Options

Additional back support on the Aeron Chair is optional, although, highly-recommended for those who sit for long periods of time or suffer from lower back pain.

Adjustable Lumbar Support (Optional)

Adjustable Lumbar Support : Adjusts to support the natural curve of the lumbar region of your spine. Lumbar support can be adjusted vertically over a 4.5 inch range. The Remastered Aeron Chair Lumbar Kit can be purchased separately and installed on the Basic Back Aeron at a later date.

PostureFit SL™ (Optional)

PostureFit SL is an optional lower lumbar back support device available on the Aeron chair. It offers the best lower back support for anyone suffering from lower back pain or discomfort. Unlike its predecessor, PostureFit SL is adjustable.

The original PostureFit was developed to provide back support that comfortably sustains the pelvis in its natural forward tilt—the position the body holds while standing powerfully upright. It did so by adjusting to fill the void between the contours of the sacral-pelvic area and the backrest. Subsequently, PostureFit has become a critical part of every Herman Miller performance chair.

Today, by incorporating adjustable sacral and lumbar support, PostureFit SL brings the technology to a whole new level. It supports the sacral region to nurture the natural S-shape of the spine, rotate the pelvis forward, and activate healthful posture—all while sitting upright. A secondary pad provides comfort and support to the lumbar region of the spine. Together, they help strengthen the spine to produce what Herman Miller calls “power posture.” PostureFit SL puts the sitter in complete control of his or her posture with the new Aeron Chair’s premier spinal support system.

Please Note: PostureFit SL™ cannot be purchased separately and installed at a later date.

About Aeron and Herman Miller

When Herman Miller released the Aeron chair in 1994, it quickly began to change the landscape. With a comprehensive approach to ergonomics, anthropometrics, and user functionality, it performed like no chair that had come before. In doing so, it also ended up looking like no chair that had come before. With Aeron, materials don’t simply contribute to the appearance of the chair, they are the design.

In revisiting Aeron for today’s work and workers, every effort was made to significantly improve upon the comfort and performance of the original, while also creating a beautiful, harmonious look-and-feel through updated colors, materials, and finishes.

Through hundreds of samples, tests, and iterations, Herman Miller arrived at three tightly curated, holistic material expressions. Graphite is the darkest, a modern take on the original Aeron. Carbon offers a balanced neutral that works equally well in warm and cool environments. Mineral is the lightest, ideal for today’s more open environments.

Created through a unique painting process, Aeron’s satin aluminum finish offers a luster redolent of high-end electronic equipment. Colors were developed to harmonize with the chair’s other components.

Details such as these contribute to a product worthy of the Aeron name, but they are not enough. Each detail contributes to a seamless whole. To simplify the specification process, Herman Miller now offers Aeron in a range of three tightly curated, holistic material expressions: Graphite, Carbon, and Mineral.

About Herman Miller
