BRAIN SLEEP is a Japan-based sleep start-up company established with the goal of solving sleep issues in Japan, the most sleep-deprived country in the world.

By leveraging our proven knowledge and advanced technology with the support from a Stanford University Professor, Dr. Seiji Nishino, we aim to awaken the potential of people and society by providing all kinds of sleep-specific solutions, including sleep research, original sleep product, and consulting for companies and sleep clinics.

There are two types of sleep: rapid eye movement (REM) and non-rapid eye movement (non-REM). REM and non-REM sleep are repeated 4 to 6 times per night, with each cycle averaging about 90 minutes of sleep. The first cycle produces the deepest sleep, and the overall quality of sleep is heavily influenced by this first cycle. The deeper you can get in these “Golden 90 minutes”, the better your sleep will be.

The key to the quality of the “golden 90 minutes” is body temperature. The higher your body temperature during sleep, the less likely you are to get deep sleep.

The reason why? – excellent air ventilation because of over 90% being air space

Because over 90% of the structure of BRAIN SLEEP is air space, heat and moisture generated during sleep do not get trapped in the pillow, inducing high-quality sleep by “cooling the brain”.

Excellent breathability is evident from experimental data.

• Check the evidence:

In fact, the data confirmed that the BRAIN SLEEP PILLOW when compared to typical polyurethane pillow, led to a higher percentage of deep sleep in the first cycle (the GOLDEN 90 MINUTES), which was also backed by sleep survey.

Fibers of different thicknesses and densities developed for better sleep change its form freely. In just 7 days of using, you can achieve an even better fit than if it were a custom-made pillow.

The three-layer and seven-gradient structure developed with Japanese patented technology, allows the pillow to fit and adapt to individual sleeping to fit and adapt to individual head sizes and habits such as sleeping positions.

• Patented three-layer structure

• Patented 7 gradient structure with varying softness

Built to be firmer on each side of the pillow. This makes it easier to turn over during sleep, reducing neck and shoulder pain.

Water washable, easy to keep clean.

• Minimal mold growth

Compared to other materials, it is evident that the occurrence of mold is low. We recommend BRAIN SLEEP for those with allergies such as house-dust, and for those who sleep with small children.

• Few occurrences of dust mites

Compared to other materials, it is evident that the occurrence of dust mites when using BRAIN SLEEP is low. Suitable for those with allergies such as house-dust, and for those who sleep with small children.

We use 100% polyethylene material which is sustainable and environmentally friendly.

With our commitment to craftsmanship, our artisans and engineers carefully perform quality checks on each item, one by one.

Prevent deterioration in quality by using natural spring water with minimal impurities.

1.  ACTIVE AIR

We’ve utilized a highly ventilable mesh material to achieve excellent moisture absorption and quick-drying, along with anti-bacterial and odor-resistant features, ensuring a comfortable experience without feeling sticky when sleeping. It also dries quickly after washing, making it worry free even on rainy days.

2. ORGANIC COTTON

A pillow cover made of fabric using environmentally friendly 100% organic cotton, grown on farmland that hasn’t used pesticides or chemical fertilizers for more than three years. Furthermore ‘COVEROSS® SUN’ technology is applied to the fabric to achieve comfort through the merge of natural materials and technology.

When you feel like the pillow height isn’t right for you anymore, simply place it under 45-50℃ (113-122℉) temperature shower and it will fluff up.

*Please avoid using water hotter than 50℃ (122℉) as it may cause damage to the material.

*For further information, please refer to the FAQs.

Through collaboration with experts in sleep research, original product development, and consulting for businesses and medical clinics, we aim to awaken the potential of individuals and society with a wide range of sleep-related solutions.

•  If you’re concerned about odor or stains: The pillow cover can be washed using a washing machine, please check the care label. The pillow itself can be rinsed with lukewarm water [around 104°F (40°C)]. After rinsing, please place it on a flat surface with good ventilation for air drying in the shade. If you’re especially concerned about odors or stains, please use a diluted neutral detergent when washing.
• How to take care of the pillow itself:  Please be careful not to fold or apply pressure to the pillow, this may cause creases or dents. When cleaning, do not use water hotter than 122°F (50°C). Continuous exposure to direct sunlight can also deteriorate the quality of the pillow. Avoid sun drying and always air dry it in the shade.
• How to distinguish between the front and back of the pillow: The pillow is labeled with stickers to distinguish between the front and back. If you’re unsure which is which, feel the threads: the side with finer and softer threads is the front, while the side with thicker and harder threads is the back.
• How to store the pillow: During the day while not using the pillow, avoid storing it in high-temperature and high-humidity conditions, and avoid putting heavy objects on top of the pillow. Avoid exposure to direct sunlight or high temperatures.

• Please note that delivery may be delayed due to, societal conditions, manufacturing conditions and weather.
• Should unforeseen circumstances arise, we will contact you as soon as possible, both during and after the campaign.
