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 covered mesh vents, a drawcord locking system, and four securing buckle straps.
We know how important it is to stand behind our products, so we offer a 10–year warranty with each Prestige cover we sell.

Our Ultima Ripstop Collection is engineered from premium materials and expert craftsmanship to offer the ultimate year-round protection from harsh outdoor elements. Made from super-durable 600 denier polyester ripstop fabric, this collection minimizes color-fading while using rot-resistant thread to maintain the covers integrity overtime. Our beautifully subtle ripstop grid pattern offers exceptional tear strength and is made to resist tearing, ripping, cracking, fading and scratching, all while providing superior coverage. Our best features have been added to protect what you love - covered vents to promote airflow and prevent mold and mildew, 4 buckle straps for added security during extreme weather conditions, a 360° drawcord for a tight fit and custom look, and a 7-year best-in-class warranty.
How to Measure Your Semi-Circle Sectional
*Run the measuring tape along the curve of the sectional keeping the tape is as straight as possible.
*If one side of your sectional is deeper than the other, use the deepest measurement.
*Place a piece of tape on the diameter line to make measuring the front depth easier.
