These slats will do the job.  Shipping was prompt and condition on arrival was fine.  There were two problems, however:  1) the slats fit a bed that is 54 inches wide, but not the 53 inch width of some full beds -- so the ends needed to be trimmed.  2) two or three days after unrolling on the bedframe, a few of the slats warped noticeably and do not lie flat on the frame, but with the mattress in place it seems stable enough.
