AirHawk seat pad
To make it short. Get one. They are great.
My old seat is getting worn out. The viynal is very near the same plushness of a GM dash board. And the foam is not what it used to be. Since I'm not a fan of aftermarket seats and I sure didn't want to have to pay for one I got and airhawk pad. It works very good. Went on a 3.5 hour ride yesterday morning and back this afteroon. Pretty much on soarness. I was impressed.
