Hard seat foarm?

[Tom Brown]

A friend of mine has built two kayaks out of wood. They are pretty much done but he needs to make seats.
Is there a pour in foam that doesn't expand too much that we can mold into the shape of a seat? It has to be able to tolerate a moist environment. Perhaps something PVC based?
Any ideas would be appreciated.

Tom,
Here is an example two part foam.

Basically pour it in a trash bag while sitting in the car (kayak). It will mold around you...
More details are available.
F1
Cart, etc..
Good Luck

Thanks for the help, gents.
He odered the foam from Pegasus this afternoon.
