OK thanks. Here is what I learned:
Density = Quality. Higher Density means higher urethane to air ratio. In the Industry they say that a Density of 2.0 or higher is Good Quality Foam. 2.1 is pretty standard for boat foam.
Compression or ILD rating. This is the firmness rating. Standard for a boat is around 48. That's with 4" thickness. If you need to go thinner, like 2-3" you might want to use A higher Compression like a 78. So that you don't bottom out.
Open Cell or Closed Cell. Closed cell means that the water cannot get into the foam. No Sponge. Open Cell means that it can get in. IF you use open, make sure its Mildew Resistant. Most manufacturers use Open Cell Mildew Resistant Foam. Closed Cell is much more expensive.
Hope that helps.
I think I will use Open Cell, 4" 2.1 Density with 48" Compression. I live in a dry climate and I don't think the Closed cell is needed.
