Bundled with a weighted base this 10 ft patio umbrella opens 79 sq ft of shade for outdoor dining lounging and poolside use. Premium polyester fabric with elegant ruffled edges resists drizzle tearing and Uv. A double-tiered top reduces wind pressure on the eight heavy-duty metal ribs. One push-button tilt rotates the canopy 30 degrees side to side. Two included sandbags fill up to 88 lbs each to anchor the cross base steadily.
