I don't know how to link but if you Google rv cushion covers there is one company that comes up numerous times. I think the name is cushion covers.com Their prices are not bad at all and you can choose from literally hundreds of different fabrics. You can get zippered covers as well as ones with just elastic that slip over cushions. One to cover my bunk was around $100 in the road map fabric. There is a place to put in your measurements and get exact prices for different fabrics so you can window shop. Hope that helps. I'm pretty good with a sewing machine and always make curtains and even quilts but cushion covers never came out like I wanted.
