Crafted With Our Premium Material
The sleek appearance of our Prestige line of covers is sure to make your neighbors curious. This heavy-duty collection is unrivaled, in both aesthetics and performance, and is designed to complement the well-planned patio.
The material is constructed of a 900-denier, solution-dyed woven polyester, making it our most colorfast fabric. It also uses an eco-friendly, waterproof backing that plays nice with your furniture's finish. This means no rubbing, color transfer, or melting. The most notable features of our Prestige covers include reinforced handles, webbing across the top of the front and back covered mesh vents, a drawcord locking system, and securing buckle straps for each leg.
We know how important it is to stand behind our products, so we offer a 10–year warranty with each Prestige cover we sell.
