First-time owner of any type of heated bedding for use with my memory foam mattress; if you own memory foam of any kind you know how COLD it gets during the winter months!! After reading about the different choices, I opted for the heated pad vs. the blanket ... and I'm not disappointed with my pick!! I purchased this Serta Damask Heated Mattress Pad a month ago because of the name, and claim this pad would have ultra-thin wires, automatic temperature and over-temperature protection, and a soft shell. I didn't consider the separate heat and control zones and automatic shut off while shopping, but they work well. I had to find a wire the first night I used it, and you practically have to pinch the pad to find them! The heat controls operate from a range of LO, then 1 through 9 and HI, for a total of eleven temperature settings. I set it to HI about 30-minutes before bed, hop in and turn down to 1 (one). On 2 (two) I got too warm, but believe I'm be cranking the temp up during the colder months, and I'm confident it will keep me toasty!! One big side effect; I find I fall asleep way faster because I am not shivering for 10+ minutes, haha!!
