My kyphosis is killing me sometimes.

Although I’ve used a lot of equipment to correct my posture, I realized: I can’t be healed totally.

Herman Miller’s Mirra 2 had helped a lot though to keep up a healthy stance and soothe my ailments in the lower & upper back.

It’s strange, isn’t it? There’s a company of people who say the Mirra 2 worths a hundred bucks and no more. On the other side, there’s a party who believes in it, as if it was the savior of office labourers.

To be honest, I situate myself somewhere in between the two: Mirra 2 is really one of the best office chairs for back pain, with some slight drawbacks.

In this Mirra 2 Chair review, I’ll try to present my experience as precisely as possible (though I don’t own a Mirra 2 at the moment). Additionally, we’ll dip our toes into a Steelcase Leap vs Mirra 2 and a Mirra 2 vs Aeron comparison as well.

Overall, what’s the real quality of this legendary task chair? Does it live up to the hype? Hop on, and let’s do a thorough look at that together.

Mirra 2 Chair by Herman Miller: State of the Art

Before getting deeper into the Mirra 2 Chair review, let’s dip our toes into visuals.

Oh, these contours.

This is the backrest of the Mirra 2. Covered with mesh since the last update.

It simply boosts every interior space.
Yes. I’m a design addict, but these unique curves may warm the heart of someone not even wearing a design glass everyday like I do.

This marvelous design distributes your bodyweight creating fewer pain points you’d have with a regular office chair.

No need to stand up and go behind the chair to adjust screws (which occasionally happened with the Humanscale Freedom chair).

Some technical details of the Mirra 2 task chair

The Mirra 2 Comes pre-assembled. Nope, there’s no need to tighten even one screw.

As you immediately notice, all the materials selected for the Mirra 2 task chair are of high-end quality.

For most parts, the chair is made of hard plastic. The so-called triFlex however merges fabric with rubber-like polymer veins, resulting in a solid, though flexible structure.

If you’d stay with a more easily cleanable version, I’d recommend buying the Butterfly back instead of the triFlex, for it’s like a simple rubber / plastic net.

No matter if you want one in your office, or at your home desk. Thanks to a number of color choices, you should find one that fits your room.

Customize it or just leave as it is

One huge advantage of the Mirra 2 Chair by Hermann Miller is that you can start using it right away. Without any customization.

However, if you feel some sort of  inconvenience, you’ll find an abundance of options to set it up to your own needs:

Adjustable lumbar support – You can reach the levers from your sitting position, on the back of the chair. You either use these to position the entire lumbar support vertically to your needs, or turn them to push the mesh outwards more.

Height adjustment lever – Okay, this might be a no-brainer. Every single office chair, even the $50 ones have this feature. The big difference here how smoothly and precisely you can set this up, compared to low-end office chairs.

Recline tension adjustment – A super easy-to-use knob solves this on your right hand side. Turn it, and you’ll feel that reclining requires more tension.

Recline fixation – You’re also able to set how much you want to lean back. You can get a more relaxed position if you put the lever into a horizontal position. Some might find it a bit frustrating, but there’s only two steps here to set the recline mechanism. You either recline way back or to the second step, but I wish there was another step in-between. You can also lock the mechanism at fully straight up position.

Tilt adjustment – This was extremely useful to me, when I wanted to lean over my keyboard a bit more. You’re able to set this with the small lever on the left hand side.

Arms – Rotate in / out angles, back and forth position, inwards / outwards position, up / down position. As you can see, you’ll be able to set them in literally every direction you can imagine.

Seat angle setup – There’s a lever underneath your seating pad, right at the front. Again, you’ll notice how easily accessible it is to make adjustments.

To be honest, this huge list had really bought me back then when I was using the Mirra 2 task chair. As you sit down, you’ll realize that you can reach every adjustment option from your sitting position.

Slight drawbacks of the Mirra 2 Chair by Herman Miller

As you know, there’s no perfect office chair for bad backs out there.

The only real issue with the Mirra 2 is that some people simply can’t live without a headrest. And unfortunately the Mirra 2 headrest is no option at all.

Herman Miller do produce headrests for the Aeron, but not for the Mirra. If you feel that you’re in need of one I’d recommend either the Humanscale Freedom or the Aeron. Freedom comes with a headrest by default, but you’ll need to buy one for the Aeron as a plus.

Mirra vs Mirra 2: What’s the difference?

One of the things Herman Miller has changed is that they applied the mesh cover onto the butterfly back making the whole feel for your back more comfortable. You can decide whether to buy one with this old Butterfly back, or the new triFlex one.

A more significant change is the curve of the seating pad, and the now more supportive frontal region of it. In the case of Mirra 2, your legs will surely have more support thanks to this slight redesign.

There’s small design change in how the arms attach to the seating pad. There’re two small curves that actually hold the arms and it fits the entire design of the chair much more.

A slight issue with the previous Mirra was that it collected a lot of dust underneath the seating pad. Thanks to a number of minor design changes, the Mirra 2 has improved a lot in this aspect.

Mirra 2 vs Aeron Remastered

A lot of Mirra 2 fans say that Mirra 2 performed in the long run way better than the  Aeron. Although I haven’t sat these chairs day-by-day for a decade, I can state that I lean towards Mirra 2 a tad as well. Here’s the two chairs compared:

Despite the fact that Herman Miller introduced the Mirra 2 as a lower-cost version of the Aeron, a lot of customers still find the Mirra 2 fit them better, and there’s no big difference in rice.

To be honest, they’re quite similar, but if you’re striving for firmer lumbar support, I’d recommend to stick with the Mirra 2.

A major differentiating factor between the two is that Aeron is made in 3 sizes, whereas the Mirra 2 is one-size.

An advantage of the Mirra 2 is that its seat’s depth can be changed optionally, so more than just one people may use it comfortably.

And one advantage of the Aeron is that it generally feels ‘lighter’ to sit in, and it flexes a bit more, compared to the Mirra, which is a bit more rigid.

Also, I’d add one more thing here: Some say that the Mirra 2 might be a bit uncomfortable, but only initially, and it performs better in the long term, especially if you have a bad back, because it offers more resistance.

Mirra 2 vs Steelcase Leap

One of the differentiating factors between the two is that Steelcase has a cushion cover and no mesh. I cannot say that either is bad or good, because this is a personal reference. I like the mesh more because it can ventilate through which is extremely useful especially in Summer.

Another difference is with durability. Exceptionally if you’re a big guy, the Steelcase Leap will probably have a more solid feeling when sitting in it.

Also, if you want to sit with one leg bent underneath your bottom, the Leap is your friend, and obviously, you cannot perform this with the Mirra at all.

Herman Miller Mirra 2 used: Should I buy?

I’ll be blunt here. No, don’t buy used Herman Miller chairs.

My reason for that is quite simple. If you buy an expensive chair used, there can be any hidden issues your vendor is not awaring you of. Although there’s a 12-year warranty for every Mirra 2 chair, I find it still risky to live with these opportunities.

If you’re on a budget, you better end off with lower end chairs every two or three years, however, you’ll have a higher environmental impact this way.

Final verdict

12 year warranty. Environmental impact is smaller compared to if you buy $100 chairs every second year. Also, a cheap chair will never look so stylish as a Mirra 2.

Keeps you straight up and won’t let you slouch that is responsible for the back ache of many of us. Good for even longer periods of sitting, it was designed to be used all-day-long.

Well, there’s one last step. Do you invest in your well-being, or you’re prepared to take some days off just because you let back pain knock you out? It’s up to you.
