Wasn't too complicated to put together once you realized the important information that is NOT in the instructions (the predrilled holes on the posts are wonky for a reason, they match the pieces they attach to so you don't attach the wrong piece). Otherwise this thing is AMAZING! We live out in the country and all we get is winds over the fields. It cuts back on that wind and gives us shade we don't have (no trees). It doesn't look like it's cheap quality like many you can find at the box stores for more of the cost. If you are looking for a pergola - this is the one you want.
