With the Patio Armor Royal Stack of Chairs Cover, your patio chairs are fully covered no matter what Mother Nature throws your way. The cover is constructed of a soft, 600 denier, 280g polyester which has been specially treated for increased UV protection. That means it will resist fading and breakdown due to prolonged exposure to ultraviolet light. The cover is then finished with a high-grade polyurethane coating for unmatched weather resistance, come rain, sleet or snow. A drawstring closure at the bottom ensures a snug, secure fit even on blustery days. Plus, vents on front and back allow for increased air circulation, reducing potentially-damaging moisture buildup. In an delightfully low-profile taupe that blends in well wherever it goes.
