I’m not sure what to do because I bought a base and umbrella together thinking they would fit each other but they don’t. I even called and waited on hold for a while before I could talk to a rep. to confirm that the base and the umbrella would match. All of this was done after they canceled my initial umbrella order because they ran out of my the color  I wanted to purchase... in any case I’m returning one if not both of these items for that reason otherwise it’s a pretty blue color and if I could put it in the base I would see if it would do what it supposed to do. You definitely need to purchase something  to hold onto this umbrella
