I don't care how many fans I point directly at my bed during the summer, the space between my butt and the mattress always reaches temperatures that make comfortable sleep entirely impossible. So, either I get a lame, inefficient AC window unit. Or I sweat my way through the brief, though surprisingly hot, Montana summers.
So far I've elected for option two, but now, thanks to some clever folks in Japan, I can cool the two inches between my butt and the mattress (the two inches that really matter) without having to pay to cool the entire room around me.
Lord this is an amazing idea. I'm about ready to fly my sweaty butt to Japan to get one right now. This extremely simple invention (by the people who brought you the USB Powered fan shirt) simply uses two ultra-quiet fans at the base of a mattress pad to pull cool air from above the head under your hot body. The device is more efficient even than regular fans. Even if used 8 hours a day for 30 days straight, it will only consume about 25 cents of electricity.

Canadian here! We use electric blankets on beds, and turn down the home heating to save goodly amounts of money on our home heating bills all winter long!

I have the hottest room in the house (2 roommates). I am sweating my butt off at night. Makes it very hard to sleep.

My spouse and I both needed something for our night sweats. We found a bed cooler that works great but beware it's not cheap. You can get it at[url= http://bed-cooler.blogspot.com...gspot.com/
