I just bought a new 2004 Grand Prix with cloth interior. After sitting in the driver's seat for a while it is very uncomfortable. It's like you're sitting top-dead-center on a wstiff mushroom. The center of support is uncomfortably on my center!
Just wondered if anyone has had any experience modifying the seat cushion contour. The salesman told me (after I had made a 700 mile trip in my new car) that they had "lots of complaints" on the early versions and the seat bottoms had been modified.
The actual seat is a steel sheet metal tray with a foam rubber pad. I think that the problem is that the stitching which runs parallel to your leg provides a trough for your leg to settle into which leaves your bottom on a square plateau.
Thanks, Dave
