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.

I had a heated waterbed for about fifteen years - that was great!
Never had any trouble with the heating element, but then it was buried
under the mattress on wood side of the water isolation bag and not
subject to stress from sleepers or folks being more active than sleeping.
Now we have a down comforter which feels warm in about twenty
seconds...and the room is kept to around 17C (roughly 62F) for the night.
