I bought this for my RV mattress because we were so pleased with the one we put on our Tempurpedic mattress last year. I had an allergic reaction to dustmites and using this has solved that problem. It doesn't get hot and there are no rustling noises even though it's a little larger than my mattress. It's easy to wipe down when I change the sheets. Bought the pillow covers too. Happy with my purchases.
