I bought this bed for my 9yr old son whom picked it out himself.  It was very easy to put together all by myself for less than an hour.  The only problem was the holes on the headboard  didn't match up, then it was extremely hard to pull the headboard apart..it would not move a bit so I just left it like that, thinking if I can't pull apart, then I know my son can't pull it apart. I put it together on my own, and took about an hour.  We love it!!
