Posture x core body temperature control. Make your body lighter for tomorrow.

Brain sleep mattress

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

Best Sleep Stanford Method

The only mattress 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?



Two important things about a mattress are body controls.

Posture x Core Body Temperature


The ultimate relaxing posture that supports your legs, hips and shoulders

Release physical and mental tension and fatigue in the "neutral posture" advocated by NASA,
which places the least strain on the body .

moreover,

Lower your core body temperature and enjoy the
"golden 90 minutes"

The quality of your sleep depends on how deep you can get in the first 90 minutes after falling asleep. If those golden 90 minutes are shallow, no matter how many hours you sleep after that, the quality will not improve.
This mattress is designed with breathability in mind, lowering your body's core temperature and leading to a deep sleep.

TECHNOLOGY

01 Float technology

Float technology
reproduces the neutral attitude advocated by NASA
did

Astronauts unanimously say that "sleeping in space is more comfortable than on Earth." When a person leans back in space, their shoulders naturally tuck in and their legs rise. This is said to be the posture that puts the least strain on the body.
Float Technology reproduces this posture. Its unique three-dimensional structure creates a floating feeling and the optimal firmness for the legs, hips, and shoulders, encouraging an ultimate relaxed posture free from gravity.


The ultimate relaxing posture that supports your legs, hips and shoulders

Leg float

Elevating your legs
improves circulation

Lumber support


Three layers of high-resilience fiber provide firm support for the lower back

Shoulder rest


Supports posture for easy breathing

Elevating your legs improves circulation and
promotes recovery from fatigue .

The legs are designed to be 4cm higher than the chest, which allows blood to circulate to the chest area more easily, reducing fatigue and swelling.

Supports smooth turning over

The lower back area, where the body pressure is most intense, is dense and firm, so it provides firm support for the body while you sleep.
The lower back does not sink in easily, so it is comfortable for those who tend to turn over in their sleep and have lower back problems.

02 Super breathable

Ultra-breathable material controls
temperature and humidity for optimal sleep

To get a good night's sleep, it is important to maintain the temperature and humidity in your bed at an appropriate level.
More than 90% of your bed is made up of air, which prevents heat and humidity from building up during sleep, creating a comfortable sleeping environment.

03 CLEAN FOR LONG TIME
& DURABILITY

It can be washed in the shower and is clean.
It is also less likely to attract dust mites or house dust.

It is easy to clean, simply wash it in the shower and dry it in a well-ventilated place.
Urethane and coil mattresses have poor breathability and tend to accumulate moisture and heat, which makes it easy for dust mites and mold to grow inside the mattress. Brain Sleep mattresses are breathable, so they are less likely to develop dust mites or mold, and can be washed any time you notice dust or dirt, so you can keep them clean.

High durability

Extremely superior resilience provides high durability. Mattress durability tests in accordance with JIS standards were conducted with a compression test of 80,000 times, as specified by the JIS standard, as well as twice the standard, 160,000 times, and three times the standard, 240,000 times, demonstrating durability. Even at three times the standard, the mattress still performed at 96.4%.

SCENE

Can be placed on top of existing bedding
or directly on the surface

The Float Mattress is designed with a firm surface that comes into contact with the bed or floor, so it is less affected by the bedding underneath or the location on which it is laid. Therefore, it can be used in any situation, whether it is placed on top of your current mattress or futon, or directly on the floor or tatami.
It has sufficient resilience and is comfortable to sleep on by itself, so it is also useful as a futon mattress when you have unexpected guests.

最高の寝心地

今年買った物の中で一番良かったです。
寝起きの腰の辛さもなくなり、最高の寝心地です。
枕もブレインスリープで、快眠です

海外
便利な3分割

3分割出来るので、立てて保管出来るので、風を通して湿気を解放出来る。また洗う時も圧倒的に軽くて便利。乾かす場所も楽でいい。使用感、寝心地も十分良い。今回2つ目を購入。海外に持ち出す場合箱が大きいので超過料金を航空会社にチャージされるのが残念。せっかく分割出来るので、次回は箱を二つに分けたいと思う。

色々失敗

【付随品】
公式サイトから購入させて貰った為安心していましたが、届いたマットレスカバーが梱包された袋はボロボロでした(カッターで切り裂いた?)、今まででこの様な扱いの商品が配送された事が無いので正直引きました。配送の際の管理環境を整備する事をお勧めします。

【製品レビュー】
腰痛持ちですが正直期待する程の実感は出来ませんでした、特に損したと感じた事は他の人の書き込みもありましたが、使用して1ヶ月で中央部がヘタリ始めた事です。排熱機能も期待以下です。
同額以下の他社製品でも同様な結果が得られる品物と感じました、腰痛は別の形で検討します。
期待してただけにガッカリです。

ルミ

睡眠時間が短い分、質を高めるためにと枕が良かったので、思いきってマットレスフロートを購入。高価なものなので、合わなかったらと心配もありましたが、口コミが良かったので。しっかりした弾力がありながら硬すぎず寝返りも楽で翌朝身体の疲れや痛みがなく、これは良いかも。旦那も腰
の痛みがないかもと買って正解でした。

うめたん

今夏の猛暑に対応するためブレインスリーブを購入しました。マットに熱がこもらず、適度な固さと相まって熱帯夜でも朝まで快適です。
