A flat pillow with a hollow rush made from supple domestic (Kyushu) rush. We created a ``indentation'' in the center of the pillow to better fit your head.
Benefits of sleeping rush:
1. Approximately 2.5 times more moisture absorption than cotton.
2. Does not get stuffy. By absorbing moisture from sweat, it lowers the temperature and promotes a comfortable sleep.
3. Reduces sweat odor. It suppresses over 90% of the chemicals that cause sweat odor. It reduces the dampness of sweat even in the hot Japanese summer.
Low-resilience urethane is used for the filling. Its features are that it is not too soft, does not get stiff, and does not lose its shape.
The surface of the rush is treated with natural Aomori cypress, which has antibacterial and deodorizing effects.
Hiba oil extracted from Hiba trees in Aomori Prefecture is processed into materials and products using the manufacturer's proprietary technology.
Hiba oil contains hinokitiol, a natural substance with extremely high antibacterial properties, and research is underway to utilize it in a variety of fields, including medicine and food.
