Chair Recommendations for a Fidgeter

I just started my first WFH and I have a one time budget for desk setup. I don't need much because my at home desk setup was pretty great already. So I'm going to order a new mouse, keyboard, and chair. I'd say I'm at 70/30 split between sitting and standing at my desk right now. I'm in a gaming chair right now which was fine on the weekends when I would be watching youtube videos or something, but now that I'm spending so many hours here I need something different.
