+1 on Brianjonesphoto response. A tractor seat, the old time sculpted one is something you can sit in for hours, without any cushions at all.
I took my stock seat from a 1 hour seat to a 3 hour seat easily. My neighbour is a professional upholsterer and furniture maker. Also does restorative work (upholstery) on old cars, boats etc and has made recovered several seasts fro cruiser riders. When I mentioned to him about my seat - he said for $20, what it would cost him, he'd make me a better seat than I could buy for $100s.
Here's how we did it.
I sat on bike, on it's centre stand, just in jeans, no riding pants and he looked at the areas where my thighs touched the sides, and where my ample butt rested against the rear. Taking those two measurements and marking the areas with chalk (first on cover, then underneath the seat pan), he took the stock cover off, the stock foam, and placed a 1-1/4" piece of hard memory foam under the drivers seat. He also took 3/4" off the rise at the rear - essentially lengthening the driver portion of the seat a bit. He also tapered the hard foam down about 1/2" on sides towards front where my thights rested.
We put the hard foam down first, then the stock, untouched foam on top and we had enough slack in the stock seat to stretch comfortably and reattach.
According to Vicenzo....soft foam compresses too hard, but since it's first, it spreads more load out over the hard foam, which compresses as well. The result is a smoothing out of the pressure points I would get when my 260lb bulk compresses only the stock foam.
All I know is it works and cost me $20 buck I now ride comfortably for 2.5-3 hours, which is the limit I would ride anyway without a stretch. The key point is when I get back on - it's like getting on the first time, you don't immediately feel any discomfort starting up. The only hared part about this is that the staples go straight into plastic - don't try a hand-tacker stapler to reattach - use an air driven one.
