With so many different styles and colors to choose from it’s no wonder why there are so many misconceptions regarding the different grades to choose from and their durability factor. The Lower grade doesn’t mean lower quality. California Patio offers Sunbrella Brand fabric choice for our products due to the durability and longevity across all grades. We offer fabric choices by each manufacturer in several grades (Grade A, B, C, D). The difference in grades is based upon several factors including materials, pattern, durability, etc. Check out our Materials Guide for a detail explanation.
