As opposed to imitation products made overseas, we don't burn fuel shipping our seats across the ocean. The cover of the Sport-a-Seat® is made from Sunbrella™ marine fabric. Glen Raven Mills, manufacturer of this fabric, takes returned and left-over scraps of material and reuses them to make new fabrics. The Sport-a-Seat® is made with high quality materials. With proper care, they can last many years. Unlike lesser quality, copycat products they aren't taking up unnecessary space in our landfills.
