Anyone know a good supplier for just memory foam or another type of harder foam? I want to replace the queen size(well kinda its a little short) in my aft cabin along with the 2 bunk style up fwd. If I could just get the foam and cut it to size myself, wrap it with an older sheet and staple that down to the wood. Then put normal bedding over that I think I would be pretty happy. These custom made mattress seem a little ridicules. Any and all other suggestions are always great, thanks guys.
