Sit outdoors comfortably in the shade with the help of this outdoor umbrella base stand. There are no traditional knobs on the rod of this umbrella base, instead there is a plastic fastener at the top which makes it even more convenient to use. You can choose different tube caps according to the diameter of the umbrella pole, and the four adjustment feets at the bottom can also help keep the umbrella seat stable and prevent tipping.
