The one thing that really helped me (and that I shared before) is to follow the specific steps in the manual for adjusting the seat position (starts at the bottom of Manual Pg 2-7). Yeh, it seems like a silly thing to do (like reading the directions on how to use a coffee cup), but it really helped me. I find that Mazda has me sitting closer to the steering wheel and sitting more upright than I ever have in any other car/truck, but it's a comfortable position for the vehicle and is what the seat is designed for. I've tweaked a little from that baseline position, but not much.
You can always save your current seat settings so as to easily revert if desired.
