I bought this from the "open box" section and saved a ton of money. I bought this bed frame because it is shown sitting inside the frame of a wood bed. I have an antique iron bed I want to use and I am hoping this bed frame will sit down inside the antique bed frame. I bought the 18 inch frame hoping it will clear the sides of the antique frame...if it doesn't I will use it alone and have lots of room under it to store totes. I gave it 4 stars as I have not taken it out of the box yet....4 stars is based only  on the  1 1/2 day  (!!!) delivery....unbelievable !!  I'll update when it take it out of the box and set it up.
