The Cover Store's quality outdoor canopy swing cover is the ideal solution for keeping your canopy swing dry and undamaged.Note: If you're looking to cover your patio swing bench only, try our smaller patio swing covers. To prevent mold and mildew from growing underneath the covers, we've included a mesh vent for proper air circulation. Also included are reinforced grommets on the bottom of the canopy swing cover to allow it to be tied down to your patio swing set. Our CoverMates? canopy swing cover is made to be simple to use, and with the zippered flap, it can be used year-round without being removed. We offer a 3-year manufacturer's warranty on every canopy swing cover we sell.
