It looks nice as a design.  The issues are about the stability of the structure.  
1. The side rails are just hooked with the head/foot boards with the metal pieces, but are not stable and the whole bed is kind of shaky because of that. I have never had this kind of issue with all previous beds before. 
2. The legs for the slats are too flimsy and they are often slided or twisted, and the slats are not strong enough. Kind of feel the bed might break any time.
3. Overall the bed is not stable and slides away easily.
