This is my favorite build so far! I love the look of this bed!
One thing I wish I had known was how long it was going to be. The bed is a good foot and a half longer than my mattress, which is a standard queen. I would recommend measuring and cutting your side rails according to your mattress - I think I am going to go back and shorten mine.
Also - I used my bed rails, instead of the slats this called for. I also used bed rail hooks (I ordered them from Amazon for $20) so that I can take this bed apart.
