Sit back and let the massager's smartsense technology accurately pinpoint your pressure points to deliver a custom massage to exactly where it is needed most. The four gel nodes are flexible and naturally roll across your back. They are enhanced with Realtouch to simulate the feeling of actual fingers to deliver an authentic shiatsu massage experience. An optional heat setting relaxes your body muscles after a long day, allowing you to sink deeper into the massage and come out fully refreshed.
