I've got a Humanscale Freedom as-well. It's a great chair. Bought one for home after using one at my previous employer. Support has been amazing as-well. They've swapped out the gel seat once and the arm rests once due to regular wear-and-tear. This is on what's now a 14 year old chair. For those recommending the Aeron - I've got one at my current job. What I don't like is that occasionally I like to sit with my leg folded under my body - fully acknowledge it's bad form, etc. but with the Aeron this is impossible due to the rigid plastic sides. For me, it's a deal-breaker for a chair I buy myself.
