Really. Do not buy this. If you're looking at  A heavier umbrella base for stability, you will not find it here. This piece comes in two main parts: the circular base and a cylindrical pipe that holds the umbrella shaft.  The only thing holding these two main pieces together is a bolt. The base is made out of a soft material and the bold is unable to keep the cylindrical pipe in place. Your umbrella will tilt, and is not sustainable to keep open while not in use. I highly recommend you search for an umbrella base that is either one piece, or offers additional support where this wonderful post and bass connect.
