not a fan of these spot type heaters. I personally would not use an underrug type heater, especially after looking at the price. a cheap portable spot heater with good safety features uncluding UL certification would be my choice if I had to resort to this.

Thanks for your response, IMO. What do you mean by 'spot' heaters, I wonder? You don't really say why you wouldn't use one-what I'm hoping to hear are some pros and cons, drawbacks or pluses and what they are. Also, I would love to hear from someone who does have one and is using it. You are right, a space heater would help, but for a number of reasons, that is not the way I'd like to solve the problem of my cold floor. Does anyone have a heating mat, or know anyone that does? Thanks.
