My husband took about 3 hours to put together with “help” from my 5 year old. He said a lot of the holes don’t match up so it took longer than he would have liked. Other than that it’s a nice bed, my 5 year old loves the very slippery slide. Also take into consideration if you have little ones sleeping on the bottom bunk my little one would bang his head on it at first when climbing in, i had to add some padding. Overall nice looking sturdy, fun bed but wish the holes would have matched up a bit better to make it easier on the hubby.
