This Sunbrella outdoor patio market umbrella is great for any outdoor patio or backyard space, at festivals, or at the cabin/camper. It is designed for use as a freestanding umbrella over a patio sofa set (base not included) or with an outdoor dining table (ranging from 42"" - 54""). The patio umbrella is engineered to last with a 103"" diameter canopy made from 100% solution-dyed 220g acrylic Sunbrella fabric. Solution-dyed means that the fibers the fabric is made from are dyed before being woven which results in a more long-lasting, fade- and stain-resistant color. The 2,000-hour color fastness means that this fabric will not fade as quickly as others. The pole and ribs are made from rust-resistant, powder-coated aluminum while the fittings are stainless steel. The umbrella's 1.5"" diameter pole means that it can fit most standard size bases. The pole is steel with an attractive speckled bronze powder coating.
