We really like the bed, BUT, it states 3" between the metal slats and they are just under 5" between the slats which makes it need a box spring under the mattress.  A platform bed requires the slats to be only 3" or less for just a mattress, as we wanted.  This was very disappointing, but, Wayfair made it right for us.  Otherwise, without their helping us, the bed frame would have only gotten a 3.  It is a very nice looking bed frame.
