Features & BenefitsNine-Foot Cord. Every one of these pads comes with a nine-foot extension cord. Therefore, even if the closest electrical outlet is located a few feet from your bed or couch, you'll still be able to use your pad properly while sitting in one of those places. Digital Controller. You'll be able to use the digital controller attached to its extension cord to adjust the heat level. Once you've adjusted it, you won't be stuck at a certain level, as you'll be able to turn it up or down in seconds when you desire. Automatic Shut-Off. This heating pad will automatically shut off after two hours, so you won't need to worry about it becoming a safety risk to you or your surroundings if you fall asleep while using it. Ideal for Sports Injuries. If you come home with a sports injury, you'll be able to quickly place your powered-up Calming Heat pad on top of the affected area, and it'll immediately start bringing you relief. After one evening of sitting or lying down with this heating pad, you may feel fine the next day, but do not lay on the pad!
