Absolutely great seat. I originally bought a Seats Inc Legacy, but I didn't like the way the seat arched my back. So I went back and bought this one instead. I love this seat. The cousin stays soft after hours of sitting in it and they are a lot of different ways to adjust the seat.
I did take 1 star off for 2 reasons. The seat is very stiff to rock back and forth, even after 4 months. The first week or 2 it wouldn't move at all. My other complaint is it really, really, really, really sucks installing this. I didn't need any sort of base, but the bolt holes are drilled under some support arms and are a giant PITA to get the bolts into.
With all that said, I would certainly buy another one of these seats if I ever bought another truck.
