|You don't have to be a Costco member to order from costco.com! I've had one of these for 3 years now, and I love it. It keeps the bed as warm as you like, using only 75 watts max per person-space when turned all the way up, which you won't want to do unless you want to turn your bed into a sauna. Very useful for getting your spouse to wear a LOT less (if any) clothing to bed!|
It uses safe low-voltage heating. How safe you ask? My kid peed on it the first night I installed it. No harm done. It's machine washable.
