I didn’t even attempt to put it together myself, though. I had the guy here who built my new deck assemble it. He said it was hard, but not so hard that he is now going to recommend it to all of his client who want him to build a pergola or other wooden structure. 

It’s solid and the materials are great. He said the assembly instructions were clear, but it was a challenge. I love it on my deck and look forward to years of use.
