I was way too warm with our new Tempur-Pedic mattress until I tried the ChiliPad™. The ChiliPad™ solved the problem and made the Tempur-Pedic mattress feel exactly the right temperature for me. I had no problem getting the ChiliPad™ just as cool as I wanted. It is also very quiet. The ChiliPad™ really does the job, I am so glad I found it.
