I'm after a chair for home office - I now work from home permanently so need a good chair.
I'm a heavy boy, so need something strong but also ergonomic. I suffer from coccyx pain, so it has to be ergonomic in this "area"

I'm looking at Herman Miller Mirra 2 right now, not as expensive as Aeron, but has all the adjustments etc
What do you guys use and do you like it?
What would you suggest, recommend?
