I've seen these for a bit over $500 on the net, and after looking at a few comparisons between Ergohuman and the Herman Miller Aeron, I've decided to go for this one due to price. I understand it's better to just sit less, and no chair can perform miracles, but as a full time uni student it's an inevitability so this is a last resort. I would love to find one of these under $500, new or used.
Thanks for your help.
