I don't know - they sent the wrong item!!  I have guests coming this weekend for a week and I have no bed for them.  I am just so upset about this whole thing.  I guess part was my fault because I didn't read the box, but I shouldn't have to.  I put it all together just to realize there were no legs!  It was just box springs.  To make matters worse, they won't be sending a replacement until Monday or Tuesday - today is Friday! Ugh!
