I love the seats in my Gen 1. I upgraded the foam in the driver bottom when I replaced the seat skin, so it's even nicer than stock. Can drive it 12 hours w/o issue. Luckily the wife feels the same, so it's what we travel long distances in.I can say the Gen 1 seats are much better than the Plat, a touch better than Tremor. 12 years old and still supportive. Very nice truck the Tremor. Owner was looking for a Gen 3, this was on the truck arriving, he bought. Gorgeous.
Seats are so subjective, even "good" seats will have those who say it hurts their back or their ass since everyone is built so differently.
The most comfortable car seats I've ever sat in, at least for a short period of time, where in a little cheap Mazda 2 that my BIL had. Like a glove.
