I don’t think I would go that route, in my opinion you have some of the best seats ever made for a truck. They are wide, lots of cushion and the built in arm rest, its great. My 07 Sierra classic with leather was by far my favorite seat. I’ve had a Gm truck model year 07, 09, 2011, 2015 then switched to Ford and the 07 gmc is still my favorite. Newer truck seats may look better but comfort counts imo.
