I have an '04 Santa Fe with the leather seat option. Love the car, hate the seats. It's not the leather, it's just that they are not comfortable, especially after an hour or so of driving. I have back problems, so any time I take an extended trip, I have to stop every 2 hours or so to walk around. Adjusting the lumbar support helps a little, but the overall seat configuration is simply not very good. Is there anything that can be one to make the seats more comfortable?
