I've been using a Steelcase Leap that I bought way back in 2008, and it's basically as good as new. Considering how much time we spend in our chairs and how (relatively) durable they are, I think making the investment in a nice one is probably not one you'll regret.

You might want to visit a local ergonomics store to test-drive, if it's practical for you -- for example, I personally don't prefer Aerons because the mesh bothers me. Those kinds of personal preferences are better to discover prior to spending $$$ on something.

Also, don't discount the rest of your equipment -- equally important to my ergonomics are wrist support and proper monitor placement. A good-quality VESA arm will also last decades and be able to follow you around. Your monitor should be about arms-length from you, with the center of the screen falling about a hand-span below your eye line.
