In order to maintain a comfortable sleeping position while sleeping, a core material is placed in the center of the pillow to prevent it from bottoming out. The chewy feel is achieved by hand-packing the inner core wrapped in soft cotton, one by one. The outside of the pillow is made of 100% cotton knit fabric with excellent elasticity, and is designed to gently follow the curves of your head, neck, and shoulders. This pillow has a low height after resting your head.
