The King size is not wide enough to go across the top of a king size bed....lacking about 4" in width.  The legs could be longer so that the frame would set higher over the bed.  I suppose it could be hung from the wall at the height desired.  Rather flimsy but at the low cost I am not surprised.  I put it back in the box and am not sure what I am going to do with it.  A hassle to get it to the post office and sent back.  I'm 78.
