Sat in the 24 way seats for over an hour yesterday. I found the backs to be flat, hard and generally uncomfortable. The lumbar adjustments push what feels like steel rods across you back at different heights. Not enough padding I would say. I later sat in a base model with the 10 way seat and it was very plush and comfortable like you'd expect from Lincoln. Problem is, I can't get those seats with ventilation in the Grand Touring. Not sure what to do.
