The KoverRoos® Tyvek Round End Table Cover offers the ultimate in furniture protection. The material, design, and construction 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® Tyvek Round End Table Cover uses technologically advanced materials that are one-way breathable - so moisture can evaporate right through the fabric, but water, 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.
