So I'd like to cut a custom closed cell pad for my ridgeruuner hammock. It's about 35/36" at it's widest point and is sort of crescent moon shaped along it's length. I'd like to buy a 36" wide piece of suitable Closed Cell foam at least 6" long. and custom cut it to fit the Ridgerunner. Does anyone know where I can buy foam that wide and long. I'd mainly be using it for summer and early spring/fall so I was thinking 1/4" would probably be thick enough. I'd like it to be soft, pliable and light weight. Can anyone point me in the right direction. The only one I've found so far is the Foam Factory.
