Same here. I went to a high end office furniture store that seemed to have all of the popular expensive office chairs I've heard of and more. I talked to a salesman (who had a similar build to mine), walked into his office ... and saw a Mirra 2 behind his desk. So I bought it. That was about a year ago and I still love it. My favorite feature is its ability to let me lean forward into the keyboard but the back follows along and gives full support. Worst problem: it has adjustable arm rests but the side-to-side motion won't lock in place. I had worried that I'd regret spending so much money on a chair. But it lets me work far more comfortably and longer without losing focus. And since my back doesn't feel torqued when I go to bed I sleep better. It's one of my better investments.
