Today, I am going to be talking about two chairs – Aeron vs. Mirra 2 – from the brand, and we will pit them against each other to see which one works the best for you.

Both the Aeron and Mirra 2 are strong, elegant, comfortable, and ergonomic chairs, but obviously, one will be more suitable for you than the other, and it can be another way round for me. User profile, preference, and need to make up a lot of decision factoring elements.

Back Support

Herman Miller Mirra 2 has two different back support options:

• Butterfly Suspension
• TriFlex Polymer

You can buy a chair with one of the two back supports. The Butterfly Suspension costs more but works like a suspension membrane, hence conforming to the shape of your back. It supports you as you move, and the mesh allows air circulation to be good.

The Triflex Polymer is designed to flex with your body position and movement to provide support, good air circulation, and also making it easier to clean.

Herman Miller Aeron has three different back support options:

• Zonal Back Support
• Adjustable Lumbar Support
• Adjustable PostureFit SL

Aeron offers back support that targets all the areas of your back. You get a good overall back support with the standard version that comes with the Zonal Back Support. The Adjustable Lumbar Support gives you a targeted and more pronounced lower back lumbar support.

The Adjustable PostureFit SL technology is an advanced lumbar support system that targets and supports specific areas of your lower back and also provides a perfect fit to your back so that you can be comfortable for hours on end.

Adjustable Armrests

The Mirra 2 wins when it comes to the armrests. Mirra 2 features 4D arms that are fully adjustable. The height can be changed, and it can be moved forward or backward, it can be moved left or right, and can be tilted sideways as well. 

The Aeron, on the other hand, has a 3D armrest design, which means it can be moved up or down, moved left or right, and can be tilted sideways. The armrests in these Herman Miller chairs are comfortable and provide sufficient support.

Adjustable Seat Depth

The Mirra 2 wins in this category as it has an adjustable seat depth that ranges from 16.25 inches to 18 inches. Aeron, on the other hand, isn’t seat depth adjustable.

Adjustable Seat Height

I feel that both the chairs tie in this category because even though Aeron has three chair size options, Mirra 2 covers the whole range in one. So, Mirra 2 is a more versatile option from Herman Miller if there is going to be more than one person using the chair, and Aeron is great and comfortable for individual use.

Mirra 2 Seat Height Range: 

• 14.75 inches to 22.25 inches

Aeron Seat Height Chair Options:

• Size A: 14.75 inches to 19 inches
• Size B: 16 inches to 20.5 inches
• Size C: 16 inches to 20.5 inches

Weight Capacity

Mirra 2 has a weight capacity of supporting up to 350 lbs, while the Aeron Size A can support up to 300 lbs, and Size B and C can support 350 lbs.

Aeron vs. Mirra 2: Which is the Best?

The brand name, Herman Miller, is enough to testify for the quality of the chairs I have been discussing. Now that I have shown you the differences, knowing which is the best is the obvious next step.

In my opinion, both the chairs from Herman Miller work great for an office setup. Both the chairs promote good air circulation and have breathable mesh backings. This allows you to sit for long hours, when you work, without feeling all sweaty and hot. Both the chairs give you the option to select different types of back support technologies to suit your needs. 

Here are some things that you can consider when deciding:

Why Aeron?

• Aeron offers three size options to customize the seat height for you, and you can get one that works the best for you.
• The back support technology is great.
• You get the option to add a headrest if you like.
• Aeron provides a more sleek, modern, and industrial look when compared to Mirra 2.

No products found.

Why Mirra 2?

• For a softer feel, you can choose Mirra 2, as Aeron projects a firmer feel.
• If you want a versatile seat height adjustment chair, then this chair is great for you.
• If you keep changing positions, then 4D armrests that Mirra 2 has as opposed to Aeron’s 3D is great to provide you arm support.
• You get the option to adjust seat depth as well.

Final Verdict

Even though Herman Miller chairs are generally pricey and can seem like an investment, they actually are! You are investing in yourself to have better support and comfort when working for long hours.

A proper ergonomic chair is important to target your problem areas and provide comfort when you work for long hours. No matter which one you choose, Mirra 2 vs. Aeron, you are bound to get the quality, support, and comfort you need and deserve.

There are other benefits to buying a chair from Herman Miller, like getting a 12-year warranty guarantee, fully assembled chair delivered, good customer support, etc. Not only that, but you also get the surety of environment-friendly and conscious production using a high percentage of recyclable material that is manufactured in a renewable energy powered greenhouse facility. It’s a win-win!
