The directions were absolutely horrible. Took several hours to complete installation (partly because we had to redo several steps because a piece was on the wrong side or upside down). Specifically, make sure the sides are correct (we flipped them and only realized later on) as well as the back and front are correct (the part of the metal frame with the holes needs to end up on top). 
Once put together correctly, we noticed that there is a fairly large gap between the side of the frame and the mattress where the slats are visible (almost 6cm). 
This bed is definitely not the quality I would have expected. I wish I had gone with something else.
