First, I will say this bed looks beautiful.  But, several pieces had cracks from hairline to worrisome in size. The wood is cheap and not very strong, several pieces you could see where a putty was used and then wood was painted over. Not what you'd expect from a bed that supposedly retails for several hundred dollars. My 38 lb, 5 year old son, climbed in the trundle bed and we heard one board crack. He told me we should snuggle and read his book in my bed because he was worried the two of us would break his. It was easy to put together and included spare parts. I have a feeling we'll be replacing the slats with better quality boards for long term enjoyment. The upper bed is a little better and stronger.
