Infinity Riage 4D Massage Chair Black

4D Back Massage Mechanism A 4D back and glutes massage mimics deep tissue massage of human hands through the use of a 4D mechanism that moves up and down, left and right, in and out (intensity), and also adds a fourth dimension of variable speed on these movements, to create the feel of a human hands massage. L-Track L-Track follows the natural curve of your back, then extends to your gluteus muscle group, for a more complete massage. 2 Levels of Weightless Zero Gravity Recline Zero Gravity elevates your feet up over your heart to improve overall circulation and reduces gravitational force on your spine for a sense of weightlessness. Truefit™ Body Scanning Special technology within the hardware and software of the chair allows the chair to pinpoint the user's size and shape, providing a customized massage specific to them.
