The bed was properly assembled, but the support piece under the slat came loose and broke in about 4 days.  We repaired it, and it is trying to do the same thing again, and legs of the support keep trying to turn sideways.  We are going to need to improvise a solution so that we continue to have the support that the underside of the bed needs.  It is an attractive bed, but the stability of the bed frame support is lacking.
