Why entrust KoverRoos® with the protection of your high quality bench or glider? In material, design, and construction, our outdoor furniture covers are simply the best on the market. Outdoor furniture covers need to breathe so that moisture can escape, keeping mold and mildew from developing under the cover. Koverroos® use technologically advanced materials that are one-way breathable - moisture leaves, but dust and dirt can't get in. Koverroos® covers are stronger than most vinyl covers, yet light weight. This means our covers are easy to use - no struggling to get them on and off. Also, these patio furniture covers are able to handle temperatures from -100 degrees Fahrenheit up to +240 degrees. The DuPont™ Tyvek® 3-Seat Glider/Lounge Cover is appropriate for most weather conditions. DuPont™ Tyvek® is a revolutionary, patented fabric ideal for covering outdoor furniture. It is extremely lightweight, and therefore easy to handle, yet surprisingly strong. It is available to protect your fine outdoor furniture exclusively at KoverRoos®. DuPont™ Tyvek® patio furniture covers are only available in White.
