High Performance Components - Exceptionally strong and durable, African Mahogany has been used in marine construction for centuries, with water based varnish that is ecofriendly and long lasting. All canopies are made from high quality marine-grade fabric designed to maintain its rich color and functional integrity for years in the most demanding outdoor conditions. The higher quality metal keeps the umbrella looking sharp and together for an extended period of time. Table Compatibility - umbrellas are large. The sturdy 1.8” pole does not fit standard tables and the umbrellas clearance when closed is too low for standard tables. Please keep this information in mind if you wish for your umbrella to be inside a table as these umbrellas were created with the idea of being placed off to the side of tables in order to cover multiple tables and chairs at once. Water based, Eco-friendly varnish for preservation of the wood grain.
