FWIW, my Herman Miller Aeron has given me sciatica over the years. That's frankly more a problem with my terrible posture and sitting position, but I wanted to note it here because we're all probably pretty bad at that. If you need a quick fix, I'd focus more on core strength and sitting posture than chairs.

I bought an Aeron 2 years ago and absolutely love it. I coupled the purchase with posture improvements and have nearly eliminated my back pain. As noted above, an ergonomic chair is only one part of the equation.

Great input, thanks.
