IKEHIKO Igusa Pillow "Mile" Concave Flat Pillow, Approx. 50 X 30 Cm, Made In Japan #3644809

This igusa (rush grass) pillow uses domestically produced denim fabric for the edges. A hollow has been created in the center of the pillow for a better fit. The benefits of igusa (rush grass) for a good night's sleep include: 1. It absorbs moisture 2.5 times more than cotton; 2. It is less likely to become stuffy. By absorbing moisture from sweat, it lowers the temperature and promotes a more comfortable sleep; 3. It reduces sweat odor. It suppresses over 90% of the chemicals that cause sweat odor. Made with supple domestically grown (Kyushu) igusa, it feels soft and smooth against the skin. The filling is made with low-resilience urethane chips. It is not too soft, but does not easily wear out or lose its shape. The surface of the igusa grass is treated with natural Aomori hiba (cypress) for antibacterial and deodorizing properties. "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 naturally occurring substance with extremely high antibacterial properties, and research is underway into its use in a variety of fields, including medicine and food.
