Took my wife and I about 6 1/2 hours to put this together. Once we got the first 2 "columns" in place, then attached it to the second 2 "columns," the process was much easier. It says to have 2 adults put this together, but getting started I would recommend 3 (but in all fairness, we did it with 2 so I guess it all worked out). Also, the instructions say to put the "feet" on the columns LAST! I would strongly recommend putting the feet into the concrete when you are SURE you know where you want to put this. Otherwise you're going to have to lift the assembled pergola UP to put the feet/concrete footings in place!! Then move it onto the footings! (Remember, this pergola weighs about 1000 pounds!!) Having said all that, the pergola looks great! Just like the picture! Smells great! we couldn't be happier! I highly recommend this item. You won't be sorry! :-)
