10 x 13 pergola- Except for the lift of the roof frame, which my wife helped with, I assembled the whole frame by myself in about 4 hours. I am now installing the roof panels which is a lot harder than it looks. Lots of cussing. LOL But after the first few I have a better idea how to do it.
It seems like it is very sturdy. My only comment is that I wish this came with covers to slide down each leg to cover the bolts used to secure it to the patio. Just a bolt sticking up and it is sharp enough to cut someone's foot.  I will by nylon bolt caps to screw on the ends. Other than that I love the way it looks.
