Grilled Paulownia Wood Cube Chips Pillow

Not only can you adjust the amount of paulownia grains inside to your liking, but the grains also flow within the cover to naturally fit each body and posture. Whether you're sleeping, lying down to read a book, or using it during stretches, this versatile pillow will transcend the concept of a "pillow" and become an indispensable part of your daily life.

Furthermore, the inner cover uses the safe material "Pashima®," made of medical-grade absorbent cotton and gauze, while the outer cover is made of "Kyoto double-layer gauze," focusing on breathability.

Yakikiri" is a traditional technique used in making paulownia chests, where the surface of the paulownia wood is charred with fire, giving it a blackened finish. By applying this "Yakikiri" technique, we have succeeded in softening the feel of the grains against your head and reducing mold and bacteria.

Furthermore, the paulownia grains are not uniform in shape; they are irregular, ranging from a few millimeters in size, some round and some angular. This irregularity creates spaces between the grains, which provides excellent breathability and heat retention. These spaces allow excess heat and moisture to escape, ensuring a comfortable sleep.

To ensure safety and peace of mind, we do not use any paints, fragrances, or antibacterial agents. This is because paulownia wood naturally possesses antibacterial and deodorizing effects, which have been confirmed through various tests. Additionally, charred paulownia wood emits a faint, sweet scent unique to paulownia. This natural aroma gently soothes your tired mind and body, leading to a restful and comfortable sleep.

Low moisture content for improved sleeping comfort
White paulownia wood grains and burnt paulownia wood grains were subjected to humidity control at room temperature of 40°C and 30% humidity for 17 hours, followed by moisture absorption at room temperature of 40°C and 90% humidity for 24 hours, and then continued to release moisture at 40°C. The moisture content during this process was measured.

As shown in the graph, the moisture content was lowered and moisture absorption was successfully suppressed by applying burnt paulownia wood.　The result is a light and comfortable sleeping surface that does not feel damp at any time.

In fact, the antibacterial properties of roasted bonito flakes have been proven through testing and evaluation by the Japan Food Research Laboratories, which checked mold counts and bacterial counts after approximately one year of use.
