good friends I have a question for you how do you make a vulcanized bench I don't know if google will translate this well but it's the fabric glued to the sponge a brand that uses this method a lot was Renault
the only way to get it out is by tearing the foam fabric
thank you for your attention
You can try to carefully skin the cover off of the foam, (some people have said that steaming the foam helps) or you can upholster your cover on top of the existing upholstery but it's always better to remove it when possible
