After my experiment using a stadium seat cushion on a long drive, I settled for using a piece of 1/2" dense foam about 13" square. It does sit me up a bit higher, but I still have headroom. It is much more comfortable not being wedged down in the seat.Yes, I have an 09 LT2 with the black ultra material. The left side of the butt -thigh is very tough and uncomfortable. And this seat material is VERY difficult to move and wiggle around in. It really GRABS your pants and holds you in place. Usually a good thing, but this stuff grabs like velcro and makes it difficult to adjust position on drives of any length.
Will likely sell this and take a beating. Its very uncomfortable.
I find the seats in my LTZ comfortable, mind you I am only 5'7..I recently purchased a 2LT and also think the drivers seat is VERY UNCOMFORTABLE! I took mine to an upholstrey shop and treid to make it better, but had no luck. Not sure what to do now. Love the car HATE THE DRIVERS SEAT! If anyone has any success stories, let me know.
