Notwithstanding that that classic 1940s song has now been denounced by feminists as part of our "rape culture", the fact remains that it is cold outside, so I recommend this heated mattress pad. I originally purchased one for myself a year ago but was so impressed after using it for just a few days that I bought more; one for Pal Nancy, then two more for Sarah, in Colorado, and Kat (Portland, OR). Universally acclaimed.
The pad is different than an electric blanket, I suppose because it lies below, rather than above the sleeper, so there's no extra weight atop: toss a light duvet on the bed and you're good to go. That's a poor explanation, but I know that I've never liked electric blankets and have therefore eschewed them, while I can attest that all the women in my life are as happy with this product's luxuriant warmth as I am.
At least at Amazon, it seems you can't get one before Tuesday, but what with all our Global Cooling, I'm sure you'll still have plenty of time to enjoy this.
(No, I haven't enrolled in an Amazon "link to product, win valuable coupons" program — I've just been impressed with this item the past two winters, and thought that some of you in colder climes might like it too.)
