Oh ny goodness! My old mattress pad had 'died,' so I searched and found this one. It was absolutely wonderful to have a warm bed! My only reservation would be that the cords running on each side from the foot of the bed to the headboard, and then  to the electric sockets should each be about a foot longer each a foot longer. There is not enough leeway for sockets that may be some distance from the bed, and the directions say not to use an extension cord.
