I thought about buying an older two piece seat. Not sure how they mount though, and I'm not sure what the stock foam looks like - or what its quality is compared to the foam I currently have to work with.
I took some pics to show what I've done so far. Once they are transferred from my phone, I'll upload them.
In my opinion, here is the flaw in the original seat. First, the back of the seat is flat, even convex a little. There is a flat ridge where it meets the rear seat. This design creates a hot spot right in the back of your rear, and right on your tailbone. Second, the flat part of the seat is also a bit convex, so it doesn't cradle you at all, it's more of a hump you're sitting on.
Basically, I ended up taking this rough scowering pad that I had in my tool area, and I started shaping the seat. I also used a round sanding disk in my drill, but controlling it was difficult at best ( although for some edges, it works quickly ) The hand scouring pad gives precise control over where you want to shape the foam. In the back I removed the edge where it meets the rear, and I've also curved it in a concave fashion. I took out a little foam where the tailbone area lands. I also started reshaping the flat part of the seat to make it just a tad bit concave, so it will cradle a little bit. So far in my testing, it feels way more comfy. I'm going to lift up the foam from underneath. I'm using this black dense rubber foam that was part of an exercise mat. I may also cut out a place for this same foam on top, because it is way more comfortable. It's has a more gel like consistency.
I've cut the rear foam off, but I did it carefully and I may reattach it. Not sure yet if I want to make it a two piece, although I think it could work.
Pics to come...
