It’s the best thing I think I have ever had for this kid!! My almost 4 yr old went from getting up out of his toddler bed multiple times a night to sleeping through and he was SO excited! DEFINITELY requires two people. I mean, it took me (a very capable, handy 41yr old woman) 4 hours to put together by myself but I needed to use a wall to support one end while placing the guard rails in and supporting the other end. It was tricky but done. 
It’s sturdy and well made!
