As a random anecdote, I own a steelcase gesture that runs about $1,100. I also own a 70$ chair from costco and I can "barely" feel the difference. I have all my settings configured correctly. I really don't buy into the the expensive officechair hype. I think it's a level of diminishing returns.
I think a $200 office chairs is about what anyone needs. That'll get you 90%+ of the way.
Where would you say you sit on the physical-dimensions bell curve?
I'd hope that the more expensive chair has better adjustability to suit a wider range of critical dimensions than the cheaper chair. But that may not matter for a lot of people.
I have a more expensive herman miller embody. It... doesn't really have much to adjust. Just the shape of the back. That's kind of an irritating aspect of it to me.
