This Electric blanket starts with super soft micro-plush fabric and decorative triple-ribbed design that is refreshingly smooth next to your skin for the ultimate in luxurious comfort. Constructed within the blanket is the patented Safe & Warm low-voltage technology. This low-voltage blanket includes a small power supply box that changes 220 volt AC home current into non-hazardous low voltage DC current (very similar to a battery) to provide warmth, protection and safety even if the blanket becomes wet. Unlike other warming blankets with their thick bulky wires, the wires in the Soft Heat blankets are so small and thin; they are virtually unnoticeable. During construction we place the thin wires 3-inches apart and evenly distribute them from head to toe. The benefit to you is a blanket that gives more of an even heat and all over penetrating warmth with no annoying hot or cold spots.
