Bought this pergola to cover our patio and its absolutely perfect. It took my husband and me about nine hours to assemble and bolt into the cement. The directions say it takes six people, but he and I did it. Its super easy. We only needed four extra people to move it about 8 inches so my husband could drill the holes into the cement. The pergola is very heavy, sturdy, and good quality. We will get very good use out of this!
