The material we use on our seats is designed to last, but nothing lasts forever. Sometimes damage and staining reaches a point where you want to cover it up. Replacing the covers with original covers requires the effort of removing the old covers. However our Revive slipcover sets solve that problem by giving you a quick, high quality and like new cover that goes on over top existing covers. Simply remove from the bag, slide the back cover over the back and close velcro closure at the bottom. Slide the cushion cover over the cushion, tie off drawstrings and you are done.
