length of the spine varies in different people, just like their height. Every human being uses their back spine to support the weight of their body, which results in tremendous wear and tear affecting the vertebrae, organs, and your body’s qi. Without renewal and direct intervention this deteriorating effect will continue. Carefit v3 bed scans the spine of each user and uses that information to offer an unprecedented, personalized thermal massage experience. This spine scan technology was not seen in conventional automatic thermal massage beds.
