Instructions do not clearly differentiate between head & foot boards. I put the extention legs into the foot board by mistake.  When I finally was able to remove them and got them into the head board -- which was extremely difficult; I had to bang them in with a mallet -- they really did not fit properly.  Assembly was further delayed, because one of the long screws was defective, requiring a trip to the hardware store. It was very frustrating! But in the end, the final product was worth it all. I would order from you again.
