Wow! I have been searching high and low over the last few years for a chair that is both and ergonomic and sleek. *Spoiler alert, I have found it’!!!!* Two weeks ago I parked my bum on the Buro Brio II (Black) and life hasn't been the same since. The elegant design is incredibly well thoughtout. With the high speed race wheels and seemingly endless levels of adjustability I am able to scoot around the office and achieve an unprecedented amount of work. Comfort, elegance and practically all rolled into one amazing lifestyle chair. The Buro Brio II (Black) is a throne fit for a king! A++++
