Not many people have noticed, but Pontiac has added about two inches of padding to the 2004 Grand Prix backseat. They started this reportedly on all cars built after September 1st, 2003. This undoubtedly is due to the bashing that the Grand Prix took in the press for having a back seat as comfortable as a park bench. The new backseat has thicker thigh blosters which stop the backseat from folding as flat, though it still will with weight applied. In looking at new cars this week, I was able to test each one of the seats at a dealer, and the new seat is definatly A+++. For those who bought earlier Grand Prix's with the "park bench" back seat, sadly Pontiac will not replacement free of charge. We have heard though that the new cushion and seat cover can be had for $200-$400 depending one where you look and your discount.
