I bought this pad for the "temperature regulation" advertised - but no, there's no difference between this and my previous, much more affordable pad. Furthermore, although it is "machine washable", it over-filled my modern, full-sized, front-loading washing machine. What's the point of a mattress pad so thick it cannot even be washed at home? This was a massive waste of money - no better than the many thick mattress pads out there, MUCH more expensive, and impractical since it's not washable in my home. I wish I'd never bought it. Very disappointing.
