A neck and back massager is a therapeutic device designed to relieve muscle tension, stiffness, and everyday stress in the upper and lower back areas. It typically features ergonomic contours that fit comfortably around the neck and along the spine, delivering soothing kneading, rolling, or vibrating massage motions. Many models offer adjustable intensity levels, heat therapy, and easy-to-use controls for a personalized relaxation experience. Ideal for home, office, or travel use, a neck and back massager promotes relaxation, improves circulation, and helps reduce muscle fatigue after long hours of work or physical activity.
