I strongly recommend a mesh chair with adjustable lumbar support and arms that raise/lower and tilt left/right.
I have one that looks very similar to this for over a year now and am super happy with it.
Compared to the "executive" style of chair, these are miles more comfortable imo and I'm not the type of guy to sit upright, pretty much always slouch and one leg either up on the desk, or on the cushion or underneath my ass. It might not look comfy, but it just is.
The one in the pic doesn't appear to have arms that move but a recliner thing instead, I find adjustable arms amazing.
Idk what brand to recommend, mine is some chinese thing I got for ~150$ from the local hardware store. Apparently the design in the picture is quite common and you should be able to find one.
Google ergonomic mesh chair and I'm sure several of these will pop.
