For my home desk I've been very happy with the herman miller setu: http://www.hermanmiller.com/products/seating/multi-use-guest...

If you get it without the arm rests, it just tucks away, and its very comfortable.

+1 for the Setu. Have 4 of them in my office and everyone loves the chair. Design is great and very comfortable. Also a great price for what you get. You can find them for $500 - $550 with some negotiating (all dealers will discount the product for you with enough persistence or if you just ask). A+ chair.
