The model is part of the Chair Doctor program that uses Artificial Intelligence to create a custom experience that is initiated by the simple touch of a button once the person is seated. It accomplishes this by reading the person’s body position, starting with the shoulders and then scanning the entire body to create a custom massage tailored to their individual body type and measurements.Chair Doctor™ Powered by AI One of the most important massage advancements to date, the Chair Doctor™ program, uses AI technology to create a massage based on your current tension and stress. Using the hand-held biometric scanner, GSR control sensors are utilized to send biofeedback information to sense your tension areas. PPG technology can read your heart rate to analyze your stress levels. The Chair Doctor™ also measures your SP02 blood oxygen levels. The program uses all of this data to provide a unique massage just for you. Dual Lumbar MassageDual air compression chambers are strategically placed in the left and right sides of the lower back to target and release stiffness. Pressure within the airbags provides micro-adjustment of the spine for unbeatable stretching and spinal alignment. The air compression areas can be independently adjusted with 3 levels of intensity. Immediate Pain ReliefCompressed spinal discs are the leading cause of back pain. If you suffer from this the Qi XE Pro offers four different stretch options. The Cozzia Qi XE Pro holds you in place, bends you backward slowly but firmly, which takes pressure off the discs in your spine providing a similar effect to a therapeutic spinal adjustment at a chiropractor’s office.
