What would have been helpful to know in advance, is that the umbrella structure ships separately from the cover.  I ordered this on sale in December, and needed to assemble in my basement.  It was tricky, but got done.  When weather permitted in March, I opened the umbrella fully on our deck and immediately a pin and washer fell off one of the ribs.  It had a manufacturing defect in that the pin was bent and the washer was also damaged.  I was able to hack a solution, but for the price paid it's annoying this was necessary.  Have submitted to Wayfair for review but have not heard back after supplying pictures and additional context.  On the plus side, the cover is substantial and overall it looks nice.
