My wife and I were looking for a bed sheet set that would complement our Tempur-pedic Queen mattress and we decided to go with the Tempur ProAir sheet set! This bed sheet set is awesome! It is very soft and comfortable to sleep on, and most importantly it doesn't get loose when twisting and turning when sleeping, it stays put in place thanks to the four corner locking system. We are very happy with it, the only thing I can mention as a minus point is, that there are only a few colors to choose from.
