The seat in my XL is very comfortable after 3 years. If I ever leave a butt print at the crime scene my seats will convict me. FYI I do have Katzkin leather on my seats.Is either ventilated? Ducting takes up space and reduces the depth of cushioning. the seats in my XL actually hold me better than the ventilated seats in our Lexus GS. The GS is ducted and has a hard plastic back. The f150 is cloth on both sides and I settle into it. The f150 seat back is starting to creak around the upper mid back now, like a worn mattress. That’s a little weird.
