   As long as the thread has been resurrected, let me report that the new Sunbeam   
   mattress pad we got when I posted in 2017 lasted three seasons when it   
   wouldn't be warm enough even at 10.   
      
   We replaced it with a Beautyrest mattress pad, and we are finishing up our   
   third winter with it.  On a scale of 0-20, we preheat at 10 about half hour   
   before we go to bed, and I put it on 3 to sleep.  So far, I don't notice *any*   
   loss of heating    
   capability with the Beautyrest as I did with repeated Sunbeam products (at   
   least three maybe four all told), which slowly seemed to go inert.   
      
   So the Beautyrest seems to be a far better product at least by my small sample.
