The Best Heated Mattress Pad.

This heated mattress pad earned the highest rating from the Hammacher Schlemmer Institute because it produced the most consistent warmth and had the softest padding. Panelists describe the 200 thread count cover and thick padding inside The Best Heated Mattress Pad as, "perfect; very comfortable to sleep on." The wires were virtually unnoticeable, leading one panelist to say, "the wires couldn't be felt unless you searched for them." Lesser models were criticized for having "bulky wires" that made the sleeping surface uncomfortable. The Best Heated Mattress Pad recorded the highest score for heating consistency, deviating only 0.13º F. The Best model has a patented safety system that monitors the voltage, current, and circuit board 120 times per second and an automatic shut-off after ten hours. King and Queen sizes have dual LCD controls that allow two sleepers to set their own temperature preferences. Plugs into AC.
