Octagonal and round patio umbrellas are available in both market and cantilever styles. If you're looking to shade a round dining table either of these shapes are ideal. For a table with an umbrella hole make sure to select one with a diameter at least 4 feet wider than your table to keep all of your guests adequately shaded. Octagonal cantilever umbrellas are also ideal to provide shade on a pool deck or over a deep seating area. Shop Treasure Garden umbrellas, Bambrella and more to find the perfect  shade solution for your outdoor area.
