ErgoChair 2 vs Aeron – What’s the same?

Both Autonomous ErgoChair 2 and Herman Miller Aeron are the big bosses in each brand. They both have great back support and feature many ergonomic adjustments.

Most of the material of these two are recyclable. And they use the mesh for the back rest as well.

Overview, ErgoChair 2 vs Aeron are comfortable with different adjustments that you can align to fit your body.

However, there are some key differences that distinguish the two chairs. So what are these differences? Keep reading the comparison to find out.


ErgoChair 2 vs Aeron – What’s the difference?

Now, let’s go into each of the differences in turn.


Both ErgoChair 2 and Aeron chairs are eco-friendly.

The ErgoChair 2 comes with polyester fabric and a molded foam interior. The frame is made of durable nylon plastic.

The hand rest pads are made of Polyurethane. 89% of ErgoChair 2’s materials are recyclable.

The Aeron chair is made of a sheer and resistant fabric that they called “pellicle”. The frames are made of glass fiber. The chair is built with 91% recyclable materials.

Color range

The ErgoChair 2 has a better range of colors with options like Cool Gray, Evergreen, All-Black, Red Apple, Black & White, and Baby Blue to choose from.

The Aeron offers three standard colors: Graphite, Carbon, and Mineral.


The Autonomous ErgoChair 2 offers a warranty of 2 years. In contrast, the Aeron offers 12-years with 3-shifts. The steep difference between the two warranty periods is due to the difference in price points.


The ErgoChair 2 requires assembly and comes with clear assembly instructions. It is not a difficult process and will take less than 20 minutes to put the chair together.

The Aeron chair comes fully assembled.

Chair size

The ErgoChair 2 comes in one size that fits all and can handle a maximum of 350 lbs. The dimensions of the Autonomous ergonomic chair are 29″L x 29″W x 46″ – 50″H.

The Aeron Herman Miller comes in three sizes (A, B, and C) based on the height and weight of the customer.

Size A chairs can handle weights up to 300 lbs. The size B and C chairs can handle up to 350 lbs. Size A, B, and C will suit heights of around 5′, 6′, and 6’6, respectively.


In this ErgoChair 2 vs Aeron battle, they both use a mesh design for the backrest. Having the mesh allows for the missing airflow, contributing to better temperature regulation.

However, the ErgoChair 2 manages to edge out the Aeron chair because of the stretch built into the Autonomous design.

ErgoChair 2 vs Aeron

Not only does it allow for a little extra expansion, but as you adjust yourself, the chair begins to wrap itself around your back area’s contours to provide additional support and customized comfort.

The ErgoChair 2 offers a comfortable 20-degree tilt and can help you recline with ease.

The Aeron has three options for the tilt of the backrest:

  • Standard Tilt: It offers an average tilt angle.
  • Tilt Limiter: A tilt limiter is a knob that restricts the backrest movement after a certain degree of tilt is selected.
  • Tilt Limiter with a Forward Tilt: The forward lift feature allows the user to tilt forward around 5 degrees if they like to lean forward while working.

Neck and head support

The ErgoChair 2 win this battle of ErgoChair 2 vs Aeron since it helps office workers circumvent the perils of the neck issue.

The ErgoChair 2 comes with a headrest built-in that has a natural curve to support the base of your head and your neck by keeping them in a neutral position.

And the headrest has both tilt and height adjustability built-in.

While the Aeron chair does a lot of things well, its design does not include a headrest.

For the comparison of ErgoChair 2 Vs Aeron, going with the Autonomous option here helps to protect you from strains and pain.

Lumbar support

Lumbar support is the next area in the ErgoChair 2 vs Aeron battle.

The first Herman Miller model uses what is known as zonal back support, which means the backrest has no features for special attention to the spine.

ErgoChair 2 vs Aeron

Adjustable lumbar support is next on the chart, which has a pronounced lumbar support area and offers height adjustment.

Adjustable PostureFit SL is the final model, and it has a more specific focus on the specific areas of the lower back.

Considering the ErgoChair 2 vs Aeron, the ErgoChair 2’s single design achieves what the Aeron chair does and more.

ErgoChair 2 vs Aeron

This chair has superb lumbar support built into the design, and the chair’s tension is also adjustable.

Furthermore, any movement makes the backrest to adjust and wrap itself to the contours of your body.

Adjustable armrest

In this area, the chair of Autonomous is absolutely the winner.

The ErgoChair 2 offers a stunning six adjustable options for the armrest. The user can rest their hand comfortably after choosing their preferred height, position, and direction.

The Aeron Herman Miller offers three customization options. The standard ones do not incur any additional charges. But as the customizations increase, so does the cost of the product.

The three adjustable options are fixed, height-adjustable, and fully adjustable.


The Aeron uses 8Z Pellicle mesh with curved and pronounced side bolsters. However, the way it is done creates some level of discomfort at the sides, and it limits the users’ range of motion.

ErgoChair 2 vs Aeron

Some users like the design, but many don’t find it very comforting. But the mesh design at least manages to keep things fresh and cool.

Autonomous uses a foam seat, which is soft and supportive. You may be concerned about the seat losing its form over time, but the design is also specifically intended to prevent that.

ErgoChair 2 vs Aeron

Everything is wrapped up in a breathable fabric, so you get freshness as well as comfort.

A review from Frederick T Pointer: “I LOVE THIS CHAIR”.

Okay…. so I’m a wannabe gamer. I spent a lot of time at my computer when I’m not working. I’ve been through about three different gaming chairs in the last five years. This is not necessarily a gaming chair, however, it is the MOST comfortable office/gaming chair I have ever owned. It’s ridiculous all the whistles and bells that this chair has. I often use a joystick and throttle with my games. I’m also in a tight space and always found it difficult to get comfortable in other chairs. With the adjustable height forms, I have found this charitable be the perfect fit for cockpit simulation. It’s very sturdy and it was very easy to put together. I love the back and neck support. If I could afford them I will get many more to outfit my living room opposed to standard couches and loveseats. I don’t care who you are and what you do, this chair can be tailored to fit anyone’s needs with all the different adjustments. I am truly amazed. It was well worth every penny and then some because I got a deal.

Jessica Gibson: “Can’t rate this chair highly enough.”

This is by far the most comfortable chair I have ever sat in. I totally LOVE this chair!!!! If I were to give any constructive criticism it would be purely aesthetic and given the alternative of an uncomfortable chair- who cares!!!! LOL That said, pick a color- it doesn’t make sense to have a light blue seat, cream arms and back of chair with grey making up everything else. It just looks silly.

Maria Wright: “Great until it wasn’t less than one year in.”

For the price I would expect better quality material. The seat is not as comfortable and I would not recommend wearing cotton while sitting on the chair. I have had my Ergo Chair 2 for almost a year. All of a sudden the it has started to squeak (I am way under the weight limits). I have contacted the company and they are sending me parts to attempt to repair the chair. I was not intending to have to take the chair apart again less than a year of having it. Hopefully the parts they send will repair the chair.

J. and J. Rudd: “This chair is awful.”

The back support was the only good part. If you are 200lbs or higher, the seat cushion is WORTHLESS, even though the weight restriction is 350 lbs. It flattens and becomes extremely uncomfortable within a few minutes of use. Also do not buy directly from the vendor. You get a 30 day trial but if you don’t save the packing materials, you get charged a BS restocking fee of 30%. If you want to brave it, buy through Amazon

A review from a customer named Kevin: “Awesome Chair! No cons at all.”

The Aeron Chair is worth every penny. Like most people in office environments, work study, play WOW have issues with finding the right chair. Having a chair that is actually sized more for your height and weight makes a huge difference by itself as opposed to one size fits all, I’m 5’11 /155 lbs, ordered the Size B, building a chair on the Herman Miller site to assure proper fit for me. Convinced its directly related to health at the end of the day, so I won’t say I wish it was cheaper because it probably wouldn’t be the quality that it is and I would be wanting to swap it out right away. Plus it looks a lot better in person, noticed I don’t lean forward, or twist and turn as much as I normally do.

The chair came in a box fully assembled as others mentioned, I did swap out the casters, not that the original ones were bad; honestly didn’t use them but to move 5 feet and back, the carpet with roller blade type casters seem to move across 1/4″ carpet a little easier. I have never been 100% happy with any chair without finding flaws just after a few hours, being in IT and previous sales, have sat in my fair share of chairs as most of us have. I’m certain I will continue to buy this chair from now on for home use.

Justin: “The only thing that fixed my lower back pain.”

Switching to working from home has caused me to not only be sitting more often, but to be sitting in my subpar desk chair. This has caused me to get lower back pain since it has no lumbar support and is not very ergonomic.

In my search for a solution to the problem I have tried 3 other chairs: Steelcase Leap v2, Herman Miller Embody, Autonomous Ergochair 2. All of these chairs were OK but had major flaws in comfort for me, especially considering the first 2 are very expensive chairs. The Leap and Embody both reclined too far back which caused upper back pain. The ergochair 2 was definitely kind of cheap in construction and was only ergonomic fully upright.

For me being kind of short and liking to sit upright the Aeron is the only chair that offers everything. And it is the only thing that has helped my lower back pain since lockdown.

Aaron Reed: “The chair will feel ok for a month.”

My work bought this chair for us when we transitioned buildings. It felt so much better on my tail bone due to the mesh fabric that I bought this one (the one I am reviewing) for my home office brand new. I alternate between this chair and standing at my desk periodically. What I found is it is causing mid-to-lower back issues for me. My back aaaaaaaches now due to the chair not having lower back support. The mesh fabric allows your lower back to roll to the back of the chair. The controls that should provide support to your lower back are very poorly built and actually put a little pressure above the lower back. It’s in the wrong spot. Don’t buy this chair. It’s way too expensive for this much back pain. Find a chair with lower lumbar support if you have a desk job.

Micheal Mathews: “Not even close to built for tall people – Caused Sciatica issue.”

When you pay $1300 for a chair built for big and tall people you really expect it to offer support for someone your size.
I am tall but not big, that seems to be a curse when looking for a chair.
At 6’5″ I weigh around 220 so while I don’t need 300lbs of support or an ultra wide seat, I do need a tall back and an adjustable lumbar.

Well while the tension on this lumbar adjusts, the height does not. It presses into my sacrum and upper glutes, and offers no support for my lower back. Consequently after enough long days I started to develop severe sciatica issues.

At first I didn’t want to blame the chair (having spent as much as i did) but after eliminating my sciatica issue the first time I went back to my desk and working for 8 hours again, stood up and, almost fell over from the pain.
Another 3 days of stretching and heat/cold ensued.
This time I ended up rolling up a pillow and pressing it down to where I needed support and after a full day of work, no issues.

What’s most frustrating is that this seems to be the trend with most “Big & Tall” chairs.
They should actually just read “Big”
This chair is not designed for a tall person. I would say if you are over 6 foot (maybe 6’2″), keep looking.

The overall build quality really isn’t that impressive compared to my last chair and while some of the adjustments are nice; This is NOT a $1300 chair.

I’ve sat in much nicer chairs with a plethora of adjustment options that cost slightly less.
An adjustable lumbar height, seat depth slider and a higher back would’ve made this a chair for a “Tall” person.
As it is now, it is built for a “Large” person but will only give “Tall” people a lot of aches and pains.
