This is the third Mattress pad that we have owned in the last 20 years. With out a doubt the easiest to set up, and more then ample to cover a king size mattress. What they don't list in the information on the mattress pad is the dual controls, which is why I bought this item. I read the reviews before purchasing and discovered from a previous customer that it came with dual controls. I like a cool bed at night but, she want it toasty when she retires. So everyone is happy!! And the price is less then the one I am replaceing which was 10 years old.
