this heating pad inflates and gives the proper support to your back when you are sitting and has the perfect heat temperatures. It's worth every penny especially if you have a stiff back or injured back.
I bought one of these several years ago, and it was great. It perfectly fit the space between my desk chair and my back, thereby keeping the heat right up against my back. This summer, I ordered one for my mother, and the one they sent was absolutely worthless. The one I got years ago inflated and stayed inflated, but the one they sent my mom this summer will not inflate at all. It is limp and floppy and no better than a regular flat heating pad (worse, since it's lumpier, without being functional as a back pillow). They seem to have changed this product for the worse. Very disappointing, and a waste of money.
The hot pad is very comfortable with the blow up feature. It is soft and contours to my back which adds comfort.
The heating pad was defective. As soon as I plugged it in it made a popping sound, all the lights flashed one time and then it died. Wouldn't turn on after that. I won't be getting another one like it.
