We live in a cold, wet area in a drafty old house. The first winter our heating bill spiked at $600 in a month. We weatherproofed and used our fireplace, which helped a lot. But, our bedroom in the daylight basement was still freezing! We had plenty of warm quilts, but getting under them in the cold basement made our teeth chatter. We got this mattress pad for our "Valentine's gift" and it has been the best thing ever! We don't need to waste money heating the whole room when we're spending the next 8 hours in the bed. It's helped continue that cut to the energy bill. It's oh-so-nice to slide into a warm bed rather than chattering your teeth until your body heat warms the area. If you're looking for something to "heat up your bed", try this!
