This is a light weight “metal” bed frame.  This replaced a “come with the bed” wooden box spring.  I was concerned that this would be significantly heavier that the wooden box spring.  It is not.  Assembly was easy. I had all the parts necessary to build the frame with “extra” parts if I were to drop a screw or something.  Once assembled, it fit perfectly on the queen bed frame and the mattress fit perfectly on top of the metal foundation.  All feels good and so far I am confident that this will last.
