My best advice is to spend some time sitting in a variety of chairs. I needed a chair 15 years ago when the Aeron was the hot thing. I tried one out and didn't like it. After testing half-a-dozen different chairs I ended up with a Steelcase Leap. I'm still using it today and it's held up really well. After about 12 years daily use the gas cylinder finally failed. It was still under warranty so a service person came to my office and replaced it for free.
