This 2-piece chair cover set protects your patio chairs from the elements, no matter the weather. Made from heavy-duty polyester, these outdoor covers are 100% waterproof and guard against fading, rain, and sun. The strap and buckle systems help secure the lids to your furniture in windy conditions, while ultrasonically welded seams enhance the protective properties and lifespan of the covers. Sewn-in vents are strategically placed for proper airflow, preventing mold, mildew, and rust build-up. To care for these covers, wash your hands with warm water.
