Seat foam?

I just mean something that won't eat up the foam. There's a LOT of glues out there that will.
Oh, I'll Bet! Even though the girl knows a whole bunch about arts and crafts hell I wouldn't even notice where to get the right phone to start with unless I went at the junkyard and started cutting it out of a spare seat out there... wait a minute now....Shhh.... I'm not even sure if that's the right way, I'd rather buy scrap new foam...
