I have always had trouble sleeping, unless it was cold enough for me to be “comfy”. My husband and I came across a mattress store in August 2009 that had state of the art mattresses upon which lay the Dual-Zone ChiliPad™. After laying on the bed for a few minutes, marveling at the coolness on one side and heat on the other, we got up thoroughly impressed and went on our way. The next couple weeks I talked obsessively about how wonderful it would be to own a ChiliPad™ and sure enough as a surprise not even 2 weeks later we went back to the store and bought one! That was in September 2009 and I have been a very devoted and faithful customer. Every time I call for customer service there is always a wonderful helpful person on the other line to help me with anything I could need or want! The latest was Ms. Becky with repairs and she helped me more than I could ever had asked for!! Thank you so much Ms. Becky and ChiliPad™ for being everything I need to be able to sleep (and save on my AC/Heat bills hehe) the way you should sleep!! It has truly been an amazing lifesaver to myself and everyone around me!
