I think it's similar with chairs.

Yeah some computer chairs are more ergonomic than others, and it's worth adjusting optimally for your posture and neck...

But also important is the ability to easily move around and change position regularly. Raise and lower seat, change tilt angle, move arm rests, sometimes use neck/lower back pillow and sometimes not, etc.

Better that than just finding the "best setting" and leaving it static forever.
