We were really excited about the bed, but we had the wood crack like this while putting it together multiple times. Not once were the screws even fully tightened or close to it. Im unsure if I should even let my son sleep in it with so many cracks and wood that is this weak, but were not willing to put another one together to struggle with so many pieces unmarked to identify them. 
We are most likely just going to buy one elsewhere and count this as a lesson learned.
