Best office chair
pmjoyce: I know it carries certain baggage with it but I love my second hand Aeron http://en.wikipedia.org/wiki/Aeron_chair.As a freelancer I've worked in the offices of a good number of large enterprises and so trialled several office chairs.  I've found that, once it's set up right for you, the Aeron is hard to beat for comfort, particularly over protracted periods.
