I'm not a big fan of massage chairs, but Sanyo Zero Gravity Massage Chair is so comfortable I can sit on it forever. It features SANYO's intelligent stiffness detection sensor technology, which diagnoses stress areas by measuring changes in pulse rate and perspiration and using the results of the finding it will provide a customized massage to relief your stiffness. The chair also moves the body into the most neutral position with diminished stress on the back. This position also provide better circulation. It will be available in Spring this year and No pricing information available yet.
