Herman Miller Mirra 1

The chair is a refurbished Herman Miller Mirra 1 that I got from a local liquidator. I tried the coveted Aeron but it just didn't do it for me. Since I spend around 6-8 hours on a chair, I wanted to get (invest?) in the best chair the money could buy. I think Mirra does the job but I don't feel like sitting on a cloud (which is what you would expect from chairs that cost a bomb).
