This bed is GORGEOUS. I bout it in gray for my young daughter and my college daughter to share when she comes home. 
While I love the construction and ease of putting this together, I have to say I did use a power drill. There was no way I was going to hand tighten something my kids were going to sleep on. None of the wood cracked or pieces were destroyed.
Also, I went to Lowes and got new slats (2 x 4) to put on the beds. I also did not like that they were rated so low for weight so I bought the Ikea Skorva mid beam, the brackets and screws (sheet metal stainless steel 14x3/4) to screw in the brackets. Now I'm confident the beds will hold my children and guest if need be.
These beds are awesome and peoe always compliment me on them.
