Looking for and ergonomic office chair

If I'm not at a job site, I'm at my desk 8+ hours a day. My current chair just isn't cutting it.

I looked around, and this seems to be a highly recommended chair at a good price point

HBADA E3 Pro Ergonomic Office Chair



I'd like to keep the price below $500, if possible. I'm going to get the boss to pay for it, and if I present him with a $2000 chair, he'll laugh me out of his office.
