This is a great loft bed for the price.  We bought it for my 12-year-old daughter and she loves it.  It is fairly easy to assemble, the instructions are easy to follow, but it is definitely a two person assembly job.  You also need two people to move it around the room.  It is very sturdy though and all the parts are connected and secure.  The Allen wrench it comes with will kill your hand by the end due to all the screws securing all the pieces.  I used a screwdriver with an Allen bit, and my hand still ached afterward due to all the screws.  However, I feel very comfortable with my daughter sleeping on this.  My only complaint is that it's squeaky/creeky.  When my daughter climbs on and off, or when she shifts her weight considerably, I can hear it creaking when I am in my bedroom.  This isn't a big deal for us though.  It is a good buy and I'd recommend it.
