You can easily glue two pieces of foam together to get any size you need. Just spray contact glue on both pieces where you want to join them, let it tack up, and stick them together. The glued joint will never come apart.
I'm thinking of dou Ling the foam on my outside cushions. The manufacturer used 2" foam, rapped is with batting on top and bottom, sealed air tight with a kind of plastic bag and stuffed it in a 4" cover. It has now all depressed. Have you run onto anything like this before and do you see a problem with doubling the foam? Thanks
