Japanese electronics giant Panasonic just released a heated rug that have a special radiant mat that sits beneath the surface of the carpet to keep things nice and warm and when I say warm I mean upto 46°C and if that is way too hot for you you can always adjust it. Be careful if you have a dog or a cat, because your pet will love this carpet. Some time ago I’ve also presented a similar product from Panasonic named No-Constraints Carpet you should also check it.- Via - Technabob
