What's important about sleep
is not just the time but also the quality

Stanford's Best Sleep

The only pillow that embodies the "Stanford
Method for Ultimate Sleep" .

We spend about one-third of our lives sleeping.
If the quality of our sleep is poor, our brains and bodies will not rest, and
we will not be able to perform at our best.
Since bedding is such an important item that we use every day, why not reevaluate its quality?


The "golden 90 minutes" determine the quality of your sleep

For Japanese people who are unable to get enough sleep,
the quality of their sleep cycle can be improved by deepening the first 90 minutes of sleep.

To do this, you need
to cool your brain.

The Brain Sleep Pillow
has excellent breathability, preventing heat build-up and cooling the brain.

RENEWAL POINT

A personal fit is achieved according to each person's head size and sleeping style .

It adapts to the size of your head and the way you sleep every time you sleep.
In addition, by adjusting the density and structure, it is 10% more durable than conventional products.

3LAYER x 9GRADATION for a personalized fit

Technology

[Unique structure that combines fibers of different thicknesses and densities]


Introducing a pillow that helps your brain sleep faster and deeper .

TECHNOLOGY technology

01 Cool your brain

Cool your brain and
sleep faster and deeper

Since it is more than 90% air-filled, heat and moisture generated while sleeping are not trapped inside the pillow, creating a comfortable sleeping environment.

Deepen
your sleep during the "golden 90 minutes" that determine your quality of sleep

It has been confirmed that the Brain Sleep Pillow has a higher rate of deep sleep in the first cycle (the golden 90 minutes) that determines the quality of sleep, compared to general functional pillows.

Even with just one hour of sleep,
fatigue recovery is 116%

When we compared the level of fatigue recovery after sleeping for 6 hours on the Brain Sleep Pillow with sleeping for 7 hours on a regular functional pillow, we found that sleeping for 6 hours on the Brain Sleep Pillow increased fatigue recovery by 16%.

I noticed an improvement
in the quality of my sleep

It was confirmed that the Brain Sleep Pillow had higher subjective ratings in terms of sleepiness, falling asleep, and recovering from fatigue compared to general functional pillows.

熱がこもらない

High heat dissipation and
no heat build-up

If heat builds up, it can affect the quality of your sleep.
This product is made of a breathable material, so it doesn't trap heat as easily as other materials, allowing you to sleep comfortably all night long.

02 Personalized fit

Patented technology allows for a 3-layer, 9-gradation structure
that creates a personalized fit for your pillow

The patented technology allows for a three-layer, nine-gradation structure that gradually adapts to the size of your head and your sleeping style.
Each time you use it, it becomes your own pillow, perfectly suited to your sleep.

A new sensation: the ultimate fit
that goes beyond custom-made

The countless fibers act as springs, providing a new elasticity that wraps around your head in a soft, three-dimensional manner while still providing a resilient feel.
Adjustment layer: Soft and fluffy, adjusts to the shape of your head
Support layer: Firmly supports your head and neck
Base layer: Hard, allowing air to escape from underneath
It also has a three-layer structure that combines the softness of the surface with durability that can withstand daily use.

Fits you perfectly every time you use it
Reduces strain on your head and neck

Test method:
Measure head pressure distribution the first time the pillow is used and one week later.
Subject: Male, height 169 cm, weight 62 kg

Supports any sleeping position

The elasticity increases as you go to the left and right, so your head won't sink too much when you sleep on your side and your sleeping position won't be affected. It fits any sleeping position, including sideways and stomach.
The 9-gradation structure also supports smooth rolling over.


03 Super Clean

Can be washed in the shower for cleanliness

It is said that humans sweat about a cup's worth (about 200ml) while sleeping. It
has excellent breathability, so it does not retain moisture and is hygienic. In addition, it can be washed with water and dries quickly, so you can always keep it clean.

Rinse with warm water (about 40 degrees) in the shower.
After rinsing, dry in the shade in a flat, well-ventilated place.
If you are particularly concerned about odors or stains, use a diluted neutral detergent.


Please note that bending or applying pressure to the pillow may cause wrinkles or dents in the pillow.
When cleaning the pillow, do not use hot water over 51 degrees. Also, the quality of the pillow will deteriorate if it is exposed to direct sunlight for a long time.

How to attach the Brain Sleep pillow cover (Organic Sleep)

Place the mesh side of the pillowcase on the inside and the hard side of the pillow on top. After adjusting the pillowcase flap inside, turn the pillow upside down before using.

How to tell the front and back of a pillow

There is a sticker on the pillow so that you can tell the front and back.
If you can't tell the front and back, please check that the side with the thinner threads that feels softer is the front, and the side with the thicker threads that feels harder is the back.

    今までに体験したことのない気持ちが良い枕です!
    横向きも、仰向けも楽です!!

    やっと見つけた硬い枕。

    柔らかな低い枕が苦手で、硬い少し高めの枕を探していました。
    硬いと言ってもしっかりとクッション性のある、矛盾した言い方
    ですが、硬くて柔らかい枕を探していました。
    やっと出会えました。おかげ様でぐっすり眠れますようになりました。

    寝心地良い

    思ったより柔らかく、初日から違和感なく使えました。
    オーガニックコットンの枕カバーにしたのですがこちらも肌触りが良く気持ち良いです。
    衛生的に使えるのがとても嬉しく、一度使うと普通の布製の枕に戻れないなと思いました。笑
    家族にもプレゼントしたいと思います。

    みー
    快適

    初めてこちらの枕を使用しました。
    スタンダードで購入したのですが、高さが合わすローに変更をすぐにやっていただきました。
    その後は、ぐっすりと寝れています。
    少し慣れない感じはありますが、使っていくうちに慣れると思います。
