Not too difficult to assemble. Very attractive. So far, has proven to be sturdy, when breezy, even though it has not been affixed to the deck (I think the vent makes a big difference). Lights have already been added to the upper frame and I'm thinking of trying an outdoor fan next summer. Since it was assembled around 2 months ago, we have spent more time on the deck. I did not give it 5 stars only because I want to see the further tests of time and weather. Overall, a very good value and I would recommend this product to a friend.
