If you have compression in the foam AKA "smooshed foam" remove all the electric gear and pour HOT water from a tea kettle over the SMOOSHED area SLOWLY. It will expand to close to new. As it was molded each little cell is flat on the outer surface but now will have a bump to it. Iron these bumps with a COLD can of your favorite beer or pop RIGHT after the hot water. Now you can use your favorite glue to re-attach the parts. Clear packing tape over gorilla glue seams helps keep parts aligned and control the OOZE. Don't try to fiddle with the ooze till its set though.
