I suggested placing a two-inch thick firm foam in the forward four inches of the seat to raise the front. I did it for comfort. It also makes the seat somewhat like a bucket seat and stops the slide forward.
I also tried the AirHawk R cushion under the cover and it didn't work for me. Stretching the cover over the cushion stops the air from moving around as it's supposed to do. I also tried one of the medium AirHawk touring seats (before I tried the AirHawk R) and didn't like it. So, I was pleasantly surprised when the AirHawk R, on top of the seat, worked so well. You may not like the way it looks, but it is very comfortable, at least for me it was.
