If you leapt directly from $50 to $900, how should I know that there aren't sweet spots between those two points?

I have never had a $900 chair and I have managed to avoid injury, but perhaps I am just especially robust?

But that was my point, I didn't leap directly from $50 to $900. I spent a lot of time looking at the space in between. What I came away with was the impression that pretty much everything under $600 was basically interchangeable junk -- the more expensive chairs in that range were just the cheaper chairs, tarted up with memory foam and the like to justify the higher price.
