Two people rarely agree on how warm a bed should be, and this King pad settles it with two controllers instead of one. Each side is set separately for temperature and for time, a feature carried by the Full, Queen and King sizes, so one sleeper can run warm while the other runs cool on the same 80-in by 78-in pad. Each controller is full-featured with a user-friendly LED display, which makes selecting a level readable in a dark room rather than guesswork by feel. Nine temperature options give real resolution across the range, and a built-in thermostat holds whichever one is chosen instead of drifting. Power draw for this size is 85W per side on a 110-120V, 50Hz to 60Hz supply. The 9-hour auto-off function shuts things down on its own, which saves energy and removes the worry of leaving heat running after everyone is asleep, and both overheat protection and short-circuit protection sit behind it. Four elastic straps anchor the 80-in by 78-in pad onto a mattress up to 10 in deep, so it will not slide or bunch overnight under the sheets, and the mattress itself is not included. Selected non-woven fabric keeps the surface breathable, soft and comfortable against bedding. The pad is machine washable for easy care, with one instruction to follow first: disconnect the power cord before washing. Setup is equally direct, since it only takes connecting the coupler, plugging in and choosing temperature and time. The box holds the pad, 2 controllers and an instruction sheet, and the King pad weighs 6 lbs with a 1.6-ft controller cord and a 5-ft power cord.
