The Vevor shiatsu back massager cushion is designed to provide relaxing back and seat massage at home or in the office. It features 2-group back shiatsu rollers that move up and down to mimic hand kneading, along with soothing heat therapy for added comfort. The seat includes 2 vibration motors to help relieve tension in the hips and thighs. Users can choose from full, upper, or lower back massage zones and adjust among 5 vibration modes for a tailored experience. A 15-minute auto shutoff adds convenient and safer operation.
