This is a good quality bed, although a bit wobbly.  Not enough to feel unsafe, but not as solid as other beds.  We haven't attached it to the wall yet so that might help a bit.  With the ladder on the side, it makes for a nice open space underneath. 
 We've put a small futon and a bookshelf underneath to make a reading space.  We have a very happy little girl in the house now.  Only problem now is trying to get her out of it.  

As others have said, the instructions are HORRIBLE!!  My advice is to look at the photo and work it out from there.  The instructions were incoherent, as if they were translated into English from another language and didn't come across well.  Don't be put off by that though, as for the price it is a good bed.  All of the holes were well drilled and in the right place.  Solid pine with only one piece slightly bent, but as this was the piece on the side, we were able to straighten it out with the bracing piece.
