This, 100%. 1) Familiarize yourself with basic chair adjustments. Every high-end chair will have some combination of these. 2) Go to a furniture store (or used furniture store) and try out every chair. Don't forget to tinker with the adjustments.

(And even better than the Leap V2s we had at an old job)
