We ordered the Tempur-Protect Mattress Protector because a regular protector didn't allow the Breeze to keep me cool at night. The store we bought the mattress from told we could use any mattress pad. After being unhappy with the Breeze not living up to it's promise, I ordered the Tempur protector, it allows the Breeze to cool, but it is so big, bigger than the mattress, it bunches up and I push it further under and it still after sleeping on it, it bunches up and makes the sheets uncomfortable. I am unsure if this is how it's made to work, but if it is, it's not very good. I like the thinness of the protector, and how soft it is, other than that, I've not been happy with it. If it fit properly, it is a great product.
