THINK MY PAD NEEDED TO BE THICKER--  MY PREFERENCE.  RUG STAYS IN PLACE WITH THIS ONE HOWEVER, SO IT IS WORKING.  HAS NOT BROKEN UP,BUT IT IS CLEANED WITH ONLY A SUCTION VAC TO PROTECT BOTH RUG AND PAD.  NICE QUALITY PAD  GUESS I SHOULD HAVE ORDERED A THICKER ONE BUT THIS WEIGHT WAS RECOMMENDED TO ME BY WAYFAIR CUST SERVICE
