The "concave center" structure stabilizes the head firmly and fits snugly around the neck. The high cushioning allows for smooth turning while relieving strain on the cervical vertebrae. In addition, the "higher sides" structure keeps the height even when sleeping on your side. *Neck support system: Research and development of pillows that provide the best position to support the head and cervical vertebrae in a natural posture. We propose a system for choosing the right pillow for each individual, seeking comfort. The three-dimensional structure fits snugly around the neck and back of the head.
