Step on the foot pedal and the whole canopy swings horizontally through 360 degrees, so shade can be aimed at a lounger or dining table without lifting the frame. A rustproof aluminum pole and eight metal ribs resist cracking and deformation, and the drizzle-resistant polyester canopy handles sun and light rain. The vented top keeps air moving and the umbrella settled. Opening takes two simple steps, a cross base adds stability, and durable rib pockets hold each rib in place. Overall size is 9.3 by 9.3 by 8.2 feet, folding to 3.3 by 3.3 by 8 feet; 37.5 pounds. A weighted base is required and sold separately.
