This is better than a heated blanket - the heat radiates from the mattress up through the sheets and coverings. It's great for soothing arthritis on cold nights too.
when it first came, there were no cords or controls. when I called customer service, she said you didn't sel electric mattress pads, I gave invoice #, she said someone would call back. No one did. 2 days later I called, a much nicer person answered, said my request would be handled asap. A few days later I got the neccessary wires and controls. Mattress works beautifully.
