Our umbrella base is your perfect partner for helping you to have a more enjoyable outdoor time. Made of a heavy-duty steel frame with powder coating, the umbrella base is not easy to rust, chip, and peel for years to come. With 2 hand tightening knobs, the umbrella stand offers a secure grip for tightening the position of the umbrella pole in windy conditions. It also comes with two flexible wheels, bringing many conveniences to take it anywhere. Because of the three adapters, the umbrella base is perfectly compatible with a 1.37”/1.49”/1.88” diameter umbrella pole, which makes it an ideal choice for a balcony, poolside, or backyard.
