In some embodiments, the support 110 may be formed of memory foam, but the present invention is not limited thereto. In some embodiments, the support 110 may be formed of soft foam, integral skin foam, polyurethane groove, etc.

In some embodiments, the support 110 may further include friction protrusions. In some embodiments, the friction protrusion protrudes in the opposite Z-axis direction on the lower surface of the support 110 in the opposite Z-axis direction and is deformed by the load of the pillow user and contacts the floor surface to prevent the support 110 from slipping. In some embodiments, the friction protrusions may be formed in a lattice shape at regular intervals on the lower surface of the support 110, but are not limited thereto. In some embodiments, the friction protrusions may be formed radially on the lower surface of the support 110 or on the support. It may be formed at the edge of (110).

In some embodiments, the headrest 120 may be formed on the upper surface of the support 110. In some embodiments, the headrest 120 may be formed on the upper surface of the support 110 in the Z-axis direction by being curved in a direction opposite to the Z-axis. That is, the headrest 120 is recessed into the central upper surface of the support 110 to accommodate the head of the pillow user, thereby preventing movement of the pillow user's head.

In some embodiments, the first neck support 130 may be formed along the curve of the neck on the support 110 at an end opposite the Y-axis of the headrest 120. In some embodiments, the height of the first neck support 130 may be 5 to 6 cm, but is not limited thereto.

In some embodiments, the second neck support unit 140 may be formed along the curve of the neck on the support unit 110 at the end of the headrest unit 120 in the Y-axis direction. In some embodiments, the height of the second neck support 140 may be 7 to 8 cm, but is not limited thereto.
