Introducing the Herman Miller Aeron Chair
The Herman Miller Aeron Office Chair is one of the most popular office chairs available today. It was first introduced by the company in 1994 and continues to be one of the top-selling models in the office furniture industry.
Thanks to the durable designs created by Bill Stumpf and Don Chadwick, the Herman Miller Aeron Chair can accommodate a wide variety of body types.
From light and petite frames to heavy and taller users — these chairs will last you a lifetime, regardless of your physique.
While Herman Miller has always taken extra care at being sustainable, they’ve recently updated the Aeron Chair design to incorporate ocean-bound plastic to the office chair body. This has helped divert almost 150 metric tons of plastic from entering our ecosystem every year.
How to identify what size your Herman Miller Aeron Chair is?
Herman Miller has made it very easy for their customers to identify which size Aeron Chairs they have.
Here’s what you should look for:
On the topmost part of your chair’s backrest and on the slope that leads right to the mesh covering the seat, feel around for one, two, or three raised dots — similar to what they use in braille.
- One dot for size A
- Two dots for size B
- Three dots for size C
If the Areon Chair you have doesn’t have the raised dots on the backrest, you may contact the Herman Miller customer support team to help you identify your chair size.
How are Herman Miller Aeron chair sizes categorized?
Going on estimates alone can get you in trouble. Your chair could arrive, and you might not be able to fit the seat at all. Or it could go the other way and be too big for your petite frame.
This is why knowing the exact dimensions of your office chair is important.
Herman Miller Aeron Chairs are popular not just for their eco-friendly components. It’s also one of the most inclusive office chair models today. Their designs are adjustable to various body shapes and sizes, making them the preferred choice for offices and large meeting spaces.
They have three (3) size categories:
- Size A (these are their smallest chair sizes)
- Size B (these are their standard chair sizes)
- Size C (these are their plus-size chairs)
When choosing what size Herman Miller chair to buy, you have to consider your height and your weight as shown in the chart above.
Here are a few sample calculations:
- If you’re 5’2” and weigh 130 lbs, then your best option is to go with a size A Herman Miller Aeron Chair.
- If you’re 5’7” and weigh 210 lbs, you should go with a size B or C Aegon Chair.
- If you’re 6’6” and weigh 120 lbs, then you should go with a size B Aeron Chair.
This isn’t a fool-proof method, and there may be some cases where the chair you get might not fit you well. A good rule of thumb is to visit a physical Herman Miller retail store to test out their available models to see which one fits you best.
|Size A – Small||Size B – Medium||Size C – Large|
|Seat Height (in)||19||20.5||20.5|
|Seat Height Min. (in)||15||16||16|
|Weight Capacity (lbs)||300||350||350|
|Base Diameter (in)||26.5||26.5||26.5|
If that isn’t possible in your area, you can always contact the Herman Miller customer support line, and they’ll help you find the best solutions for you.
What size categories does Herman Miller have for other chair models?
Herman Miller has several other chair models available in their store. We’ll be naming a few of them along with their size categories to help you decide which size would be right for you.
1/ Herman Miller Cosm Chairs
The Herman Miller Cosm Chairs are available in low-back, mid-back, and high-back versions. Besides being ergonomic and eco-friendly, these chairs are also customizable, so you can choose their arm measurements, colors, as well as what type of fabric to use for coverings.
You can also choose among three armrest designs (leaf arm, height-adjustable arm, and fixed arm) to see which feels the most comfortable for you.
|Depth: 26.7”||Depth: 26.7”||Depth: 26.7”|
|Width: 26.7 – 29.3”||Width: 26.7 – 29.3”||Width: 26.7 – 29.3”|
|Height: 34 – 40”||Height: 38.6 – 44.9”||Height: 44.9 – 51.2”|
If you prefer not to have armrests, you can also choose to leave them out during the personalization process.
2/ Herman Miller Embody Chairs
The Embody Chairs are Herman Miller’s second best-selling models. They’re popular for their pixelated support mechanism that allows a user’s weight to be evenly distributed as they sit.
The great thing about the Embody Chairs is that they automatically adjust to a user’s recommended settings. No need to tinker with a lot of knobs and levers — the chair can accommodate your every move, ensuring that you’re well-supported all throughout.
Unfortunately, the Embody Chairs are only available in one size, the dimensions of which are as follows:
|Country of Origin||USA|
|Overall Dimensions||29.5”W x 26.5”D x 42-45”H|

If you’re planning to get this model, we recommend you visit a Herman Miller retailer, so you can try the seat out before buying it.
3/ Herman Miller Mirra 2 Chairs
You can choose between two types of Mirra 2 Chairs: the Work Chair and the Stool.
As its name suggests, the Mirra 2 Work Chair is great for those who spend long hours sitting in front of a desk. It’s designed to adapt to the slightest movement and adjustment made by the person sitting on it, giving its users complete comfort as they work.
The Mirra 2 Stool, on the other hand, is perfect for those who alternate between standing and sitting positions as they work. Architects, engineers, and artists are the most common markets for this design.
When you buy the Mirra 2, you can choose between the Butterfly and TriFlex backrests. Both offer incredible support and flexibility. The only difference is, the Butterfly backrest has a fabric layer while the TriFlex backrest has none.
Read the complete dimensions of each Mirra 2 Chair version from the Herman Miller chair manual to get a clearer view of what’s in store for you.
