Deep kneading and rolling massages at the neck, upper back and lower back help relieve muscle tension and improve blood circulation and also treat upper and lower back pain. Built-in double vibrating motors at the hip relaxes the body and strengthen metabolism. Unique up-down motion of the massage nodes was designed with the concept of somatology. Multiple massage heads work together to imitate real full body kneading and rolling massage with human hands. This massage cushion has three massage variations-full back, lower back, and upper back massage-making it versatile and perfect to use in the office or at home. A great product if you're looking for a lower back massager with heat!
