Query: Herman Miller Mirra Review

Product looks great and is ergonomically well designed. Armrests are very cushiony which was a nice surprise/plus. People who want a cushiony chair, should not order this chair. However, anyone who sits for long periods at a desk will notice less back aches due to it's stiffness and ergonomic design.The chair would be awesome with more adjustment capability but for us, the price of those adjustments couldn't be justified. All in all, we really like the look and the ergonomic design of these chairs! Very nice quality product.
