Stability is the theme here: a square base with four large reservoirs takes 135 pounds of water, 185 pounds of sand or 220 pounds of the two combined, and a cross base underneath spreads the load. The aluminum pole and eight reinforced ribs carry a 10-foot square polyester canopy that blocks sun and shrugs off wear, with a vented top to reduce movement. A crank handles opening and closing, 360-degree rotation moves shade through the day, and locking pins assemble the stand. Base plates stack for off-season storage, and large spouts speed filling and draining. Umbrella 10 by 10 by 9 feet, 56.5 pounds.
