"Sturdy fiberglass frames and repellent fiberglass team up to create super-durable umbrellas that can withstand small gales and big elephant sneezes. The 9-foot canopy lifts into the air with an easy mechanism. The separately controlled infinity tilt can shield you from the sun at any point in its fiery orbit. Each umbrella is designed to cover 48-inch round tables. However, the right base (not included) can support freestanding configurations as well.
