table warmer
I have a Sunbeam twin size bed warmer which I sometimes use. It basically gets used once or twice per week... as I save this one for my outcalls. (This will be it's third winter.)
On the other hand, I also have a Thermophore, which was part of my MT school equipment package. And I can't tell you how many of my clients have RAVED about how great the heated table is. Suffice it to say, MANY. (This will be it's seventh winter.)
The great thing about the Thermophore, is that I believe it's said to pull humidity from the air, thus supplying the client with Moist Heat.
The bad part is it only has one setting, on or off. However, that doesn't bother me to much. It's well worth the money, and as stated your clients will appreciate the extra little bit of concern and what they perceive as "luxury". Though they say the Thermophore costs only pennies per day to use.

I personally have been using the Thermophore for nearly seven years now, and I have a M.D. who I massage weekly. She always has cold hands and feet, and we joke how she won't even let me in her house without one of my table warmers! I'm serious, even in the summer! Since we live in the Northern climes, it's maybe once week per year that I might not have to use it. LOL She liked them so much she asked me to find one of the Sunbeam one's in Queen size for her bed. She wanted to climb off the heated massage table and go right upstairs into a nice warm bed after her massage. I found her one at Wal-mart of course, and now for her... life is good. LOL
Heating the table seems like such a little thing. But it becomes a "Value Added Service", something inexpensive for you, but just what your clients need to see you as spoiling them, and setting you apart from your competiton in their eyes! ;D
