My office chair broke down, so I was in the market for a new one. My neighbor let me borrow his Aeron chair for a couple of days (he has two). My wife insisted I buy the same chair as she has at work. Upon checking, it turned out she has an Aeron. Having tried the Aeron, I loved it, but after a week of reading as many reviews on the Herman Miller chairs as I could, I kept getting drawn to the Mirra.

The things that stood out to me about the Mirra, compared to the Aeron:

(1) I liked the design better than the Aeron's. I find the Mirra a beautiful chair, whereas the Aeron looks, well, not ugly, but standard.

(2) I liked the Mirra's one-adjustable-size fits all approach. With Aeron you have to pick an A, B or C size. I'm in the B/C size category per Herman Miller's chart. Herman Miller then recommends you get the B chair (which is what I borrowed from my neighbor). I figured you probably keep adjusting a chair over a long period until you have the perfect settings. I did not want to end up in a situation where I would always wonder whether the C size would have been better for me. With Mirra, there is only one very adjustable size--if you buy the right chair (see below).

(3) Mirra's moving back looked better than Aeron's more rigid back. In theory of course, because you cannot really make the comparison unless you try both chairs for many days.

(4) Mirra is cheaper than Aeron, but not by much (if you get the right chair, see below).

Having had the chair for three days, I'm extremely happy. My lower back pain, caused by my broken chair is finally gone. Aeron would have done this as well no doubt. The chair looks great. The assembly was done in two minutes.
