I have to thank Wayfair's staff for this. I was mulling over which umbrella stand to buy for a 9' Market umbrella, and there were so many to choose from.  I ordered a wonderful table, the umbrella and decided to wait. When I called to change location of delivery, I mentioned to the representative that I needed a base, but couldn't make a decision.  He was great....asked pertinent questions (where is it going, size of umbrella, etc). Next thing I knew an email from Wayfair came over sending info on a few bases, but I was intrigued with this "Industry Standard"...I loved the weight (50 pounds) which meant winds were much less likely to affect it, or the umbrella. More importantly, it wasn't going to detract from the table or umbrella, just do its' job in a subtly, low-keyed attractive kind of way....and price for a well reviewed stand was great.
