Whether you’re on your feet all day or you sit for long hours at a desk typing, tension and fatigue can really play havoc with your back muscles. The Beetla 3D Shiatsu Back Massage Cushion with Heat uses 12 deep-kneading massagers to move up-and-down, side-to-side, and even front-to-back along the curve of your spine to help improve circulation and relieve tightness. And when your back muscles are fully loosened, your whole body will feel better.
