After checking box stores and Amazon, I had found a couple of possibilities for a large umbrella to use at our pool, but was hesitant to buy those because of reviews and limits on the umbrella size.  All others that I looked at were plain in appearance, so I decided to purchase this beauty from Wayfair.  It is definitely heavy enough to support the oversized umbrella, even when wind gusts came up unexpectedly - and we have had many compliments on the sundial base!
