This was a beast to put together, and I am very used to putting furniture together myself.  The screws would not tighten for anything and I had to get some replacements from a local hardware store.  It looks nice now that it is finally erected, but the frame definitely needs to be anchored to the deck it is sitting on.  It does seem very sturdy; the frame has held up over the past few weeks to some extremely windy weather.

Update: We had a storm come through and the metal frame bent and the top cover ripped.  This thing has been the bane of my existence for the last month - choose another option.

Second update: After a month a second round of storms actually snapped the steel in 2 places.  These are Wisconsin thunderstorms, not Florida hurricanes.  Wayfair was wonderful and gave me a full refund, but do not buy this gazebo.
