Soft Heat Luxury Micro-Fleece Electric Heated Warming Blanket is probably one of the most plush warming blankets you'll ever have the luxury of snuggling up in. That's just one of the wonderful features of this blanket because within the incredibly soft micro-fleece fabric is the pantented Safe & Warm low-voltage technology. This low-voltage blanket includes a small power supply box that changes 120 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 bulky wires, the heating wires in the Soft Heat blankets are so small, they are virtually unnoticeable and also give more of an even heat meaning-no hot or cold spots. The twin size blanket comes standard with one easy to read, easy to turn, non-slip computerized controller to adjust the temperature of the blanket. With an automatic pre-heat and hold feature you simply turn it on and the blanket will warm up on HI until it reaches the temperature that you pre set your dial on and then adjusts itself to hold it there. For your safety and convienience it has an automatic shut off feature that will shut the blanket off after 10 hours just in case you forget. It also comes standard with built in over-temperature protection for that extra bit of safety and piece of mind. Easy care feature means that it's machine washable and dryable and will not stretch, pill or shrink giving you many years of warm luxurious use.
