Didn't want mine to be loose, or tear my new covers. When I did my interior a few years ago, I had an upholstry shop put the new covers on the new foam. They also rebuilt up the back seat foam and put that cover on. Came out great. I think it was $300 or so. A little steep, but I don't think I am gentle enough to do upholstry work like that. A breaker bar can't used!
