It was actually pretty easy to put together rventhough the instructions don't really tell you how to put it together. Only thing that confused me for a moment were the pieces you put into the adjustable bar and the corner cap.(it's used to conect more panels toogther but it doesn't tell you that)
I really like that it is the entire length of my kids twin bed and even with the bar at its lowest level it is very tall. I do wish they made a shorter length for the end of a twin bed though.
