I made a large crash pad out of a mattress and some ensolite pads and nylon fabric. It worked well, then I moved to the West Coast. My folks are tired of it sitting in their garage, so I'm looking to find it a new non-dump home. I don't know how to post pictures here, if you are interested, email me jrcl atgoeshere uw.edu and I'll send you a picture. You would need to pick up in North Salem NY. Don't bother responding to this post, I don't use this forum.
