Assembly was not simple. Lots of nuts and bolts.  The lower ring where the umbrella should go through is so low that it does not either go over the top of an umbrella stand or sit above it.  You should specify the clearance from the ground to the bottom of that ring or suggest an umbrella stand that fits underneath it.  Also, delivery was 3 days later than originally promised.  This was my first Wayfair purchase and I am not impressed.
