A high-end chair like the Mirra 2 comes with a big price point. You might get a price as low as $1070 if you go for the most basic option and with a fully loaded option, it might cost you up to $1500.

However, I have got a deal of fully loaded Herman Miller Mirra 2 that costs $649.99 right now on Amazon, however it’s refurbished. You can check the most updated price here.

I’ve checked back and forth the feature on the Herman Miller website and on Amazon, they are offering the same specs which costs on Herman Miller website $1345, and on Amazon, it costs $979.

On the other hand, an Aeron chair might cost you $1095 – $1995, depending on the materials you choose.

Aeron chairs have great resale value, and remastered Aeron is available for around 700 bucks. However, Brand new Aeron chair costs a lot on Herman Miller’s Official website, with the fully loaded option, it can cost up to $1995.

The Mirra 2 also balances instant comfort and self preferred ergonomics in a single, sophisticated outlook.

After many years of trying and fixing, the Aeron has implemented and has gathered thousands of user feedback on how to make a working chair more and more comfortable while keeping it ergonomic and better build quality. 

The Aeron chair came out long ago, and now it has gone through a remastering to support people’s backs as they go about working all day.

To be honest, both of these chairs are pretty strong and well-built. But the Mirra 2 feels heavier. 

The Aeron chairs are proven to last for 10-15 years very easily because of their strong built quality. If you look around you will find that very easily.

If you buy either of these chairs you won’t have to worry about build quality or durability ever. Both of these chairs come with 12 years of the extended warranty, which is really cool.

Design & Comfort: 

Today Herman Miller is known for their modern viewpoint & contemporary design sets, particularly when it comes to chairs. The question is thus, what makes a Herman Miller chair so distinctive and comfortable? 

Firstly, the designers took a long time which expanded over a decade, to stall the design, and they looked at their customers’ demand for an extended period of time. 

They figured out what makes an office chair worth those extra bucks. They tried to create chairs that are much more than just a thing to sit on. They curated products that are really good for customers’ well-being and comfort. 

“You can’t design without empathy,†said Jeff Weber, who’s the designer of Herman Miller,  which implies they understand how it feels to sit through long hours of the day in an uncomfortable chair/workspace.

Their exceptional craftsmanship and work ethic put comfort and functionality at the top. They’ve earned their reputation over a long period of time which means they’re quite trustworthy.

Customer Satisfaction:

Herman Miller has been in the game for quite a long time and they’ve had the opportunity to perfect the design to the customers’ liking for multiple decades with their constant feedback. 

You can go for Herman Miller chairs with no worries as they’re bound to be good, which they usually are, and their quality control is top-notch. 

Surely, one or two reviews can be impacted because of personal use cases, but the majority says they’re good to get despite their prices.

Even a refurbished chair can cost almost as much as the new one which says a lot about the brand.

Purchase & Return Policies

Built by the same company, both of these chairs have the same policies, including a whopping 12-year long warranty that comes from their level of skilled assembly and material quality, which is quite uncommon for the other chair brands. 

They have a service plan onsite offered by the company for repairs. Also, they both have an included return policy which exempts one from the charges of shipping with a full refund in case you’re not feeling comfortable with the chair. 

So, Which is better, Aeron vs. Mirra 2?

The Aeron Office Chair is obviously the better choice in every possible way.

I think Aeron has a better design, ergonomic features, and it is slightly more comfortable than the Mirra 2.

Don’t get me wrong, sitting on Mirra 2 is a very good experience. But it feels more soft than it should be.

On the other hand, The seat of Aeron has the perfect balance of firmness which is actually better.

Make Your Choice:

Even if the Aeron chair is the clear winner. You must consider the pricing as well before making a choice. 

In case you’re looking for a comfortable ergonomic chair, both offer a few of the best available options out there on the market in 2021.

If the seat has to be used particularly by a single person and you have the budget, then Herman Miller Aeron is the better option.

But if you are not willing to spend more, then you can go for the Mirra 2 as well. 

However, I think as of today, it’s better for you to buy Aeron for 1000 bucks from Amazon. You can find it by clicking here.

Aeron chairs have tremendous resell values, and I don’t think anyone should choose Mirra 2 over the legendary Aeron chair.
