This supportive pillow made of high-density memory foam instantly adapts to the contours of your neck for a more personalized fit. Its ergonomic shape is slightly tapered at the back to ensure the optimum resting position when sleeping upright. It provides support around the neck and allows the head to lean back and rest comfortably. An adjustable front closure provides an even better sleeping experience and keeps the head and neck securely in position to prevent unexpected movements.
