Fast, Deep, Brain Sleep.Awaken tomorrow's performance.

A pillow born from brain and sleep research.

Even with limited sleep, achieve
ultimate fatigue recovery and strongest awakening.

The only pillow that
integrates the methods of
"Stanford's Best Sleep."

Approximately one-third of life is spent sleeping. Poor sleep quality prevents the brain and body from resting, and you cannot unleash your full potential.
Pillows are very important for improving sleep quality.

In fact, even with one hour less sleep,
fatigue recovery and morning awakening improved.

What's important for sleep is not just "time but quality."

Sleep quality is determined by
"the golden 90 minutes"

For Japanese people who often don't get enough sleep, deepening the first 90 minutes of sleep can improve the quality of their sleep cycle.

What's necessary for that is
cooling the brain

Brain Sleep Pillow
cools the brain with excellent breathability to prevent heat buildup

Furthermore

Achieving a personal fit
for each individual's head size and sleeping style.

Every time you sleep, it adjusts to your mattress and the size and sleeping style of your head.

Every time you sleep, it adjusts to your mattress and the size and sleeping style of your head.

TECHNOLOGYTechnology

01Cool your brain

Cool your brain,
sleep faster and deeper

Because over 90% of the pillow is made of an air layer, heat and moisture generated during sleep do not get trapped in the pillow, creating a comfortable sleeping environment.

Deepens sleep during the "golden 90 minutes"
that determine sleep quality

The Brain Sleep Pillow was confirmed to have a higher percentage of deep sleep during the first cycle (the golden 90 minutes), which determines sleep quality, compared to general functional pillows.

116% fatigue recovery
even with one hour less sleep

Comparing fatigue recovery between 6 hours of sleep with the Brain Sleep Pillow and 7 hours of sleep with a general functional pillow, it was found that 6 hours of sleep with the Brain Sleep Pillow resulted in a 16% increase in fatigue recovery.

More details about the evidence

実感した睡眠の質の向上 Quality of sleep improved

The Brain Sleep Pillow was found to have higher subjective ratings for sleepiness, sleep onset, and fatigue recovery compared to general functional pillows.

熱がこもらない

High heat dissipation,
no trapped heat

Trapped heat can affect sleep quality.
This product is made of highly breathable material, so it is less likely to retain heat compared to other materials, allowing for comfortable sleep all night long.

02Personalized fit

A 3-layer, 9-gradient structure
that achieves a personalized fit
with patented technology

A 3-layer, 9-gradient structure that gradually adapts to the size of your head and sleeping style has been achieved with patented technology.
With each use, it becomes your own personalized pillow for optimal sleep.

A new sensation
The ultimate fit that surpasses custom-made

Countless fibers act as springs, creating a new sensation of elasticity that is both resilient and softly cradles the head.
Adjustment layer: Softly and gently adjusts to the shape of the head
Support layer: Firmly supports the head and neck
Base layer: Hard, allowing air to escape from below
It also has a three-layer structure that combines surface softness with durability for daily use.

Fits you better with every use
Reduces stress on your head and neck

Test method:
Head pressure distribution measured after 1st and 1 week of pillow use
Subject Male, height 169cm, weight 62kg

Supports any sleeping posture

The elasticity increases towards the sides, so your head won't sink too much when sleeping on your side, preventing your sleeping posture from collapsing. It adapts to any sleeping position, whether on your side or stomach.
The 9-gradient structure also supports smooth turning over during sleep.


03Super clean

Washable with shower for hygiene

It is said that humans sweat about one cup (approx. 200ml) while sleeping.
With excellent breathability, it does not retain moisture and is hygienic. Furthermore, it can be washed with water and dries quickly, so it can always be kept clean.

What to do if you feel the pillow height doesn't suit you

STEP 1: Pour hot water (45-50°C) for about 60 seconds
Place the pillow on a flat surface and pour hot water over the areas you are concerned about.
Avoid pouring hot water while the pillow is propped up or under pressure, as this may cause deformation.

STEP 2: Pour cold water for about 15 seconds to set the fluffiness
Tap water temperature is fine.
*The effect may be reduced if tap water temperature rises during hot summer days.

STEP 3: Air dry in a well-ventilated, shaded area
Lay the pillow flat to dry.
Avoid direct sunlight or hot air drying.
If you want to dry it faster, wrap the pillow in a bath towel and gently shake it up and down to remove excess water.

How to care for it?

If dirt or odor is a concern, clean with shower water.

① Rinse the entire pillow with shower water.
If dirt or odor is particularly bothersome, use a diluted neutral detergent.

② Air dry flat in a well-ventilated, shaded area.
To dry faster... Wrap the pillow in a bath towel, gently shake it up and down to remove excess water, then dry.

【Precautions when cleaning the pillow body】
Avoid propping it up, bending it, placing objects on it, or applying pressure during maintenance, as this may cause creases or indentations in the pillow.
Do not use hot water above 51°C.
Avoid direct sunlight or hot air drying.
Hair products or cosmetics may cause discoloration. Please note that if the material itself discolors, it cannot be restored to its original color even with cleaning.

I don't know what height is right for me.

We recommend choosing the height based on your physique and preference. STANDARD is generally recommended. If you prefer a higher pillow, HIGH is recommended; if you prefer a lower one, LOW is recommended.

How to attach the Brain Sleep Pillow Cover (Organic Sleep)

Place the pillow cover with the mesh side facing down, and the hard side of the pillow facing up. Adjust the flap of the pillow cover inside, then flip the pillow upside down to use.
*Please use the pillow with your head resting on the mesh side.

How to distinguish the front and back of the pillow

The pillow has a mark to distinguish the front and back. Please use the pillow with the marked side facing down. Also, please do not remove the mark when using.
If you are unsure which is the front or back, the side with finer, softer fibers is the front, and the side with coarser, harder fibers to the touch is the back. Please feel it to confirm.

Precautions during storage

When not using the pillow during the day, store it in a place that avoids high temperatures and humidity, without placing any weight on it.
Avoid storing in direct sunlight or in high-temperature locations.

AWAKEN YOUR POSSIBILITY AWAKEN YOUR POSSIBILITY

For those wondering how to choose a pillow

Tips for choosing the right pillow ① Know the ideal pillow height
Correct pillow Pillow that is too low Pillow that is too high
  • ✓ When the height is right, your gaze is slightly downward from directly above.
  • ✓ Your neck and shoulder muscles are not strained.
  • ✓ Your throat is not constricted, making it easy to breathe.

A pillow should not be too high or too low. If the back of your head is too high, your neck can be compressed, leading to neck and shoulder stiffness, pain, and snoring. Conversely, a pillow that is too low can cause your head to be unstable, putting a strain on your neck and shoulders. Generally, when lying on your back, the ideal sleeping posture is when the angle of inclination from your neck to your head is 10-15 degrees, and your chin is 0-5 degrees lower than your forehead.

Tips for choosing the right pillow ② Back sleeper pillow? Side sleeper pillow? Choose based on your sleeping posture
  • Side sleeper pillow

    For back sleepers, we recommend a pillow that allows your neck bones to form a gentle S-curve, just as when you are standing straight.
    Choosing a pillow with a height close to the thickness of your shoulders will give you the ideal height.

  • Pillow that is too low

    For side sleepers, we recommend a pillow that allows the bones from your head to your back to be straight, just as when you are standing straight.
    Choosing a pillow with a height close to the height of your shoulders will give you the ideal height.
    Even if the "Low" pillow is perfect for back sleeping, the "Standard" pillow might be a better fit for side sleeping.
