Sadly, I should have known by the lack of information and the answers to the Q&A, that I would have problems "marrying" the cantilever umbrella to this stand.  There were no instructions to be found in the box and the umbrella I purchased, which fits the vague Q&A info, did not seat to the metal tapped posts in the stand.  I tried to contact Customer Service to which I was disconnected several times.  What would be great is if Wayfair would tell you in their product pages, which umbrellas could be matched to which stands. Now, I need to either box up the stand or umbrella and order a different replacement and take my chances all over again, or return both and buy local.
