I am sleeping better with this warming pad, although I have to remember to turn it on 1/2 hour before using it. The warmth spreads throughout. The only criticism I have is that it doesn't really cover my combo mattress/boxspring very well. I had to pull up from the bottom to move the plug-in and label off the top of the mattress. It would work best with a separate mattress and boxspring, but I adjusted it to work.
