Comfort Level

What does your office chair need to be? Comfortable, of course!

We know that if you are stuck in an uncomfortable chair for a long time, you will become restless because of the lack of comfort and eventually lose concentration on your work.

Mirra 2 and Aeron both provide you maximum comfort with their contoured seat cushioning, adjustable back support. Are they have the same comfort level?

Indeed no. So let’s explore the comfort level of both chairs, we will compare the top 3 comfort points Backrest, Armrests and seat comfort.


Aeron’sAeron’s PostureFit SL backrest supports the spine in any position compared with Mirra 2, which is unstable if you don’t adjust it properly.

You can set the Aeron chair at one of three recline postures. We like the adjustable lumbar support of Mirra 2, it’s shown to be superior, with the ability to control depth separately on both sides of your back.

Mirra 2 provides good spinal support when you sit upright.

Its Poly backrest is easy to clean, breathable and flexible. The flexibility of Herman miller Mirra 2 makes it the perfect choice for those who need to work in different positions.

But one downside of the Mirra we saw it’s Poly Backrest is hard. The Butterfly Back is a better choice if you prefer a soft feel on your back instead of the TriFlex polymer Back.


There is no difference in the armrests of both chairs. Both Aeron and mirra2 provide adjustable armrests.

Mirra 2 has an excellent height range; it’s best for people with heights between 5’45and 6.4 ft; it means Mirra 2 chair can fit almost all heights, it’s very impressive.

The armrests of Mirra2 are covered with soft material for extra comfort. its fully adjustable arms have a waterfall design on the front.

The Herman Miller Aeron Armrests are also padded and adjustable. The Aeron has just a little more when it comes to padding, and they have some small bumps that you can rest your hands on.

You can adjust both chairs’ arms in pivot, width, and depth. Adjustments like these allow users to find the perfect position for them.

Seat Comfort

Seat comfort is one of the most important factors to consider when buying a new ergonomic chair.

Mirra 2 use AireWeave Mesh, which provides excellent elasticity, but the overall feel of the seat is stiffer. Some people prefer stiffer feelings, while others find them uncomfortable.

On the other hand, the Aeron seat is designed to give you breathable comfort.

Aeron provides superior flexibility and a soft touch because of its 8Z Pellicle mesh seat.

The mesh allows your skin to breathe freely, so it keeps you cool and comfortable even if you work for a long time.

But one downside we notice in the Aeron seat is it has no adjustable seat depth adjustment, which means you are stuck with the regular seat depth, which can be a problem for big people. But overall, Aeron has a more comfortable seat.
