This gazebo is well made and sturdy. Each item is numbered for easy identification. My wife and I installed it ourselves, albeit with a few difficulties. Some steps really require a third or fourth person (e.g., bolting the front and back joist assemblies on the standing posts).  It says the total assembly time is 4 hours, but it takes about 10 minutes just to remove the protective plastic off each (6) of the edge trim pieces (10x6=60), so that's one hour right there. The total accumulative time for my wife and I to install the gazebo was about 25 hours, but that includes a few steps that we had to do over.

Recommendation for BACKYARD DISCOVERIES: Some pieces should be marked "front" and "Back" in addition to the item number.  Item G04 Facia is one of them. Item E01 Rafter is another.
