Stumbled upon this while searching for a back massager. Scored a pretty good deal on a Homedics one on Amazon which instantly shot up in price after I purchased, otherwise I would have posted that. This Sharper Image one might be an even better deal than I got on the Homedics.
Says it's down from $294 on Ozsale, but listed as much as $329.99 (Myer). Reviews seem decent across a few US sites.
-Chair-pad massager - Add this to any chair, couch or recliner to create the best seat in the house. The straps allow it to securely fit onto almost any chair.
-Smartsense Technology:
-Bodyscan - Pinpoint body scanning for custom massage
-Conform - Pivots to the contour of your back
-Realtouch - Massage action with 3D movement
-Heated - Soothing for deep relaxation, feel the warmth as the optional heat mode relaxes the tension away in your back, shoulders, and lumbar.
-Gel Notes - Natural touch comfort with soft flexible gel nodes that act like fingertips to give you the feeling of a real massage at home.
-Compact for easy relocation
-AC power
Homedics on GGCommercial is $214, $10 post, FYI
The homedics has a dedicated neck massager. Although I find that I hate it and it tends to throw my back out. So the homedics may actually be the worse choice for some.
