I love the color and size of the umbrella. However, the product image and description are deceiving as it does NOT come with a base (as pictured) that can be filled with sand. It comes with a base that has to be bolted into the ground. I purchased this particular umbrella precisely because it could be a free-standing umbrella due to the base. 
That said, I chatted with a rep at Wayfair, and she was able to get me a base without charging me due to the inaccurate website description. Unfortunately, it's not the base that is made for this particular umbrella, and we haven't had a chance to install it yet so don't know for sure that it works.
