TECHNOLOGY

01Cool your brain

Cool your brain and sleep faster and deeper on tropical nights

Since more than 90% of the pillow is made up of air layers, heat and humidity generated while sleeping do not build up inside the pillow, creating a comfortable sleeping environment even on hot tropical nights.

The "golden 90 minutes" that determine the quality of your sleep have a lasting cooling effect

By thoroughly cooling your head during the first cycle (the golden 90 minutes) that determines the quality of your sleep, you can sleep comfortably even in the hot and humid summer.

A special ice pack that does not interfere with your sleep or
impede breathability

The gel used does not harden even when cooled in the freezer, so the pillow remains comfortable to use and sleep on.
In addition, the size of the pillow does not interfere with the ultra-breathability that is a feature of the Brain Sleep Pillow, so you can stay comfortable until morning without heat or moisture building up inside the pillow. It
can be used all year round by cooling it in the freezer in summer and in the refrigerator in spring, autumn and winter.

02Comfort fit

Patented
3-layer 9-gradation structure

The Brain Sleep Pillow's three-layer, nine-gradation structure makes it easy to turn over and fits your head gently, and now it has an ice pack pocket, recreating the same sleeping comfort as the Brain Sleep Pillow.

New sensation,
the best fit

Countless fibers act as springs, providing a new elasticity that wraps around your head softly and three-dimensionally 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
Ice pack pocket/ice pack: A pocket with minimal specifications that does not interfere with your sleeping comfort, and maintains a soft sleeping comfort even when frozen

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.
Its excellent breathability prevents moisture buildup and makes it hygienic. In addition, it can be washed with water and dries quickly, so you can always keep it clean.

FAQ

How do I care for it?

[Pillow]
▼If you are concerned about odors or stains,
the pillow cover can be washed in the washing machine. Please check the washing instructions. The pillow body can be washed with water. After rinsing with shower water, dry in the shade in a well-ventilated flat place. If you are particularly concerned about odors or stains, use a diluted neutral detergent.

▼Precautions when caring for the pillow body
Please note that folding or applying weight may cause wrinkles or dents in the pillow. When caring for the pillow, do not pour hot water over it. Also, if you continue to expose it to direct sunlight, the quality will deteriorate. Avoid drying in the sun and always dry in the shade.

[Ice pack]
If you are concerned about dirt, wipe it off with a tightly wrung wet towel. Please refrain from using a washing machine.

Storage precautions

[Pillow]
When not using the pillow during the day, avoid high temperatures and humidity and store without placing any weight on it. Avoid storing in direct sunlight or in places that get very hot.

[Ice pack]
If stored wet, mold may form, so store in a dry place. Store out of reach of small children and pets. Be careful not to place heavy objects on the pillow when storing.

Can I use Organic Sleep and Active Air in addition to the pillowcase "Brain Sleep Pillow Cover Perfect Cool EX"?

Yes, you can. We recommend the Brain Sleep Pillow Cover Perfect Cool EX because it has a high cooling effect and can be used comfortably even in the summer. In seasons other than summer, you can use it all year round by using Organic Sleep or Active Air.

Can I exchange sizes?

This product is available in one size only, standard size, and we cannot accept exchanges for other pillows.

How to attach the cover

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.
*Please use the pillow so that your head is on the mesh side.

How to tell the front from the back

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.

Do you need air conditioning?

Recently, summers have been extremely hot, with many cases of heatstroke occurring while sleeping, so we recommend using the heater in conjunction with an air conditioner depending on the room temperature.

Can it be used in seasons other than summer?

Yes, you can. We recommend that you refrigerate the ice pack during seasons other than summer.
Even if you use the ice pack without refrigerating it, you can experience the same fit as the Brain Sleep Pillow by placing it in the ice pack pocket of the Brain Sleep Pillow Perfect Cool.

    冬は保冷剤なしでも涼しい

    寝てるときに、首周りに汗をかいて夜中起きることが多かったのですが、こちらの枕を使用してから、夜中起きることが減りました!朝まで涼しく寝られて快適です!

    匿名
    買って良かった!

    枕難民だった私ですが、2024年に購入したもので一位と言って良い商品です!
    今年は夏の暑さに悩まされましたが、この枕のお陰でヒンヤリ!そして、ストレートネック、肩の痛みでどんな枕でもなかなか寝付けなかったのが解消されました。

    たっつん

    結論から言うと、寝つきが良くなりました
    布団に入ってから寝るまでの時間が半分ぐらいになりました
    通気性、フィット感、アイスバッグの効果が大きいと感じています。以下に詳しくまとめます。

    通気性★★★★★
    - 手で押した時に風が通るぐらい通気性が良い
    - 1晩中蒸れがなく快適に使える

    フィット感★★★★
    - 購入時は高く感じだが、だんだん高さがあってきた
    - ファイバー枕の中ではかなり柔らかいと感じるが、しっかりと支えられている感覚もある
    - 左右に行くほど、反発が強くなり横寝でもしっかり支えてくれた
    - アイスバッグの存在は感じる。店舗で試したスタンダードモデルの方がフィット感が良かった

    アイスバッグ効果★★★★★
    - しっかり冷気を感じる。入れると明らかに寝つきが良くなる
    - 結露などは感じられず、快適に使える

    眠りに悩んでいるなら間違いなくおすすめです!!

    ゆりこ

    今までの枕だと頭がポカポカになってしまい、夜中に暑くて目が覚めてしまうことがあったのですが、この枕にしてから熱がこもらず、朝まで目が覚めません。そして、保冷剤入れると少しひんやりして、寝つきがとても早く快適に眠りにつけます。

    枕カバーだけでなく枕自体も洗えるし、清潔に長期間使っていけそうで、良い買い物をしました。

    高額なので、購入をずっと躊躇していましたが、買って正解でした。夫婦で2つ同時に購入したのですが、もっと早く買えばよかったと少し後悔しているほどです。

    最初の頃は、朝起きた時にアイスパックを冷蔵庫に戻すのを忘れることもありましたが、今ではすっかり習慣になりました。

    マットレスはさらに高額なのでまだ決心がついていませんが、首が楽になった分、背中や腰の重さが気になるようになり、購入も時間の問題かもしれません。
