This cushion provides heat and massage therapy. Five powerful massaging motors relax and relieve knotted back muscles, loosen tense upper shoulder muscles and relieve stress and stiffness of the neck muscles. It includes 10 built-in strategically placed power bio-magnets (950 gauss each) that promote blood circulation and oxygen in muscle tissues and acupressure points. Lumbar support alleviates pressure from incorrect posture and protects lower spinal discs. Includes AC and DC adapters, plus a controller which allows you to adjust heat and massage settings.
