Grade A
Grade A is the introductory-grade Sunbrella fabric. It is made from polyester or polyester blends. While it is water, mold, mildew and stain resistant, it is not color-saturated and so color can fade with exposure to the sun and rain. The grade A fabric is ideal for use in outdoor furniture that is in well-protected patio areas. It is also the most affordable version of Sunbrella fabric on the market.
Grade B
The mid-range option of Sunbrella fabric is known as grade B, and is made from a base of olefins. This improves the fabric’s ability to resist fading, stains and deterioration. Grade B Sunbrella fabric is a relatively softer material than grade A. With its better ability to withstand wear and tear, grade B Sunbrella fabric is an ideal (but still affordable) option for use when pets and children are around.
Grade C
Grade C Sunbrella fabric is a premium-grade fabric made exclusively of acrylics, the fibers of which have been solution-dyed for total color saturation. This grade attracts the highest price point but is also the most resistant to wear and tear and fading. It’s ideal for use in heavily-frequented places such as restaurants and cafes. Some people also recognise a grade D of Sunbrella fabric, but this is essentially the same composition as the Grade C, being differentiated by more intricate design patterns and specialized weaves.
