Special 3D structure to deepen your sleep.
Uniquely designed based on [Neck Support System]The "central recess" construction allows the head to be firmly stabilized, and fits perfectly to the neck muscle.Provides high cushioning for smooth tossing and turning while reducing strain on the cervical vertebrae.In addition, the "height on both sides" construction keeps it high even when you sleep on your side.
*[Neck Support System] is a research and development of the pillow that can be achieved in the best position to support your head and cervical spine in a natural posture.
[Neck for Both Use] The neck is "High" and "Low" so you can use one pillow to distinguish the one you like.
[Adjustable Height] The inner side of the pillow contains a urethane sheet of 0.8 inch & 0.4 inch (2 cm) & 0.4 inch (1 cm) thickness adjustment, so the height can be adjusted up to 1.2 inch (3 cm) increments.In addition, the 0.8-inch (2 cm) urethane sheet is divided into 2 partitions, so you can adjust the height of the neck and back of the head.
