Which are the best office chairs for attorney office?

My friend has just started to work at an attorney firm and they let him select his own office furnitures. He has a pretty decent budget, but probably it's not a good idea to spend all of it. He is not quite sure about interior styles. Should he go for classic, contemporary or ultra modern? It's a traffic and business law attorney firm if that matters.

contemporary is good encough.
