Twenty-two pounds of resin and steel is what keeps a patio umbrella upright when the wind picks up, and that is exactly what this base brings to the deck. The molded surface copies a woven wicker pattern in bronze, so it reads as part of the furniture rather than a slab of weight. Two adapters drop into the 10 inch steel tube to match poles of 1.5 or 1.9 inches, and a hand-tightening knob clamps the pole without any tools. Resin and steel together shrug off rain and sun, and the finish resists rust through a full season outdoors. The round body measures 18 inches across and stands 13 inches tall, low enough to sit under a table. Assembly is straightforward with the illustrated instructions supplied. The umbrella itself is sold separately.
