Brain Sleep Pillow

Brain Sleep's flagship product, the Brain Sleep Pillow, was developed through brain and sleep research based on the theory of the best-selling book, The Stanford Method for Better Sleep. This pillow focuses on the "golden 90 minutes" that determines the quality of your sleep, and improves the quality of your sleep by cooling the brain.

Feature 1: Custom-made fit that prevents neck and shoulder pain

It features a unique three-layer structure. The top soft layer changes to fit the size and weight of your head, providing a fit that goes beyond that of a custom-made product.
In addition, the center is the softest, and the left and right sides have a "9-gradation structure" that makes it more elastic, so it fits any sleeping position, including on your back, side, or stomach. Furthermore, the wide design of 60 cm makes it easy to turn over in your sleep, improving the quality of your sleep.

Feature 2: Cools the brain and helps you sleep quickly and deeply

Cooling the brain deepens the first 90 minutes of sleep and improves the quality of sleep. It is said that if the quality of these 90 minutes is poor, the quality of sleep will be poor no matter how many hours you sleep after that. The Brain Sleep Pillow is made of woven polyethylene, and compared to other materials such as urethane and feathers that are often used in pillows, it can maintain a high heat dissipation rate even when you sleep for a long time, so it is possible to keep the temperature of the head low. You can sleep comfortably without heat or humidity disturbing your sleep.

Feature 3: Can be washed at home so it's always clean

Because it is made of woven polyethylene, dirt is unlikely to soak into the material and become difficult to remove, and dirt can be easily removed with a shower. It is recommended to clean it about once every three months, but since it can be hand washed at home, you can wash it completely when you notice dirt or odor and keep it clean at all times. The pillowcase can also be washed in the washing machine.

Furthermore, the material is resistant to dust mites and mold, making it safe for people who suffer from house dust or allergies, or who sleep with children.

Brain Sleep Mattress Float

The Brain Sleep Float Mattress is a medically inspired mattress that uses the latest patent pending "Float Technology" to regulate blood flow and body temperature.

Feature 1: "Five gradient structures" make it easy to turn over in bed

The highly elastic tubular fibers used in medical and nursing care facilities are intertwined in three dimensions in various directions, supporting the body from all directions and distributing body pressure evenly. The center is the softest and the elasticity increases toward the left and right, creating a "five-layer gradation structure." It has moderate resilience and a resilience that does not sink too much, making it easy to turn over in bed.

Feature 2: Special design of shoulders, hips and legs for ultimate relaxation

Inspired by the neutral posture that humans naturally assume in a zero-gravity environment, the pillow supports you at three points: the shoulders that support breathing, the waist that fits supportively with three layers of highly elastic material, and the legs that are designed 4cm higher than the waist. Simply by lying down, you can unconsciously assume the ultimate relaxed posture.
This posture is believed to facilitate the circulation of blood and waste products that have accumulated during the day, and also to be effective in reducing fatigue and swelling. It relieves tension throughout the body, which leads to stress reduction, while at the same time deepening your breathing and taking in more oxygen, helping you wake up refreshed in the morning.
In addition, since more than 90% of the mattress is made up of air layers, it does not trap heat or moisture generated while sleeping, creating a comfortable sleeping environment.

Feature 3: The mattress itself can be washed in the shower

Just like pillows, they can be easily washed in the shower. Regularly washing the mattress, which absorbs sweat and sebum, will help prevent the growth of dust mites and mold.

Brain Sleep's research also showed that the Brain Sleep Mattress, made of polyethylene, is more breathable, distributes body pressure, is easier to turn over in, is easier to clean, is easier to carry around, and is more durable than mattresses made of memory foam or coils. It also shows that the body sinks less into the mattress than urethane or feather mattresses. This means that the burden on the body is less, and you can enjoy a comfortable sleep.

Brain Sleep Comforter All Seasons

The Brain Sleep Comforter All Seasons uses an innovative temperature control technology developed for space suits. The unique microcapsules change from solid to liquid in response to temperature changes, repeatedly absorbing, storing, and releasing heat.

Feature 1: Cool when it's hot, warm when it's cold

It absorbs excess heat when it's hot and releases stored heat when it's cold, so it keeps the temperature inside the bed comfortable (33°C ±1°C). In addition, it has a reversible structure with a cool touch and a warm brushed material, so it can be used all year round, keeping you cool in the summer and as an inner blanket in the winter.

Feature 2: Reversible design means you can't take it off 365 days a year

You can use either side of the fabric depending on the season. In warm seasons, you can wear the cool-to-the-touch fabric against your skin, and in cold seasons, you can wear the soft, smooth peach skin fabric to gently wrap you in comfort.

Feature 3: Easy to wash and keep clean every day

It can be washed in a home washing machine, so you can easily clean it whenever you want.

Brain Sleep develops a variety of bedding products to meet the needs and concerns of our customers regarding sleep. We will introduce the features and key points of our recommended items.

Brain Sleep Comforter Weight Balance

The Brain Sleep Comforter Weight Balance is the ultimate medical futon that goes beyond a down comforter and helps your brain and mind rest.

Feature 1: Warmer than down & side weight structure keeps heat in

Developed using a new technology, Air-in-Ball is made from yarn in which about one-third of each fiber is hollow. By trapping air in the hollows and creating a layer of warm air, it achieves heat retention comparable to that of down, as well as the lightness and softness of air. It keeps you warm all the way down to your toes.

It is said that people turn over in their sleep about 20 to 30 times. If the futon moves when you turn over, cold air will enter the bed and disturb your comfortable sleep. However, the Brain Sleep Comforter Weight Balance has a unique side weight structure (weights on both sides of the futon) that prevents the edges of the futon from slipping off, so you can keep warm until morning.

Feature 2: A "weight balancer" that gives your brain and body a break

It is said that applying moderate pressure (compressive stimulation) is ideal for naturally relaxing and sleeping. This is called the "hug effect," and by getting a sense of security similar to that of being hugged, the brain and body can rest, improving the quality of the sleep environment.

A typical gravity futon makes the whole body heavy, which is far from the comfort that a comforter should provide, but Brain Sleep has developed a unique position for gravity. The weight balancer (weight) puts the right amount of weight on the chest, applying pressure to the body and creating a feeling similar to that of being hugged.

The balancer uses soft elastomer pipes that are soft and highly breathable. The pipe shape prevents heat and stuffiness from building up, so it won't disturb your sleep. The special olefin resin is soft, so there is no rubbing noise, and the soft feel keeps you comfortable until morning.

Feature 3: Machine washable to keep it clean

Unlike down comforters, many of which cannot be washed at home, this product can be washed completely in a home washing machine.

Feathers lose their oils and become wilted each time they are washed, so they are unable to maintain their volume. However, the filling used in the Brain Sleep Comforter Weight Balance is ball-shaped, so the fibers are less likely to break and the fluffy volume is maintained.

The side fabric is also downproof, meaning the gaps between the threads are crushed to allow only air to pass through, preventing the filling from blowing out.

Brain Sleep Coin (App & Device)

"Brain Sleep Coin" is an app and device that uses sleep research and advanced AI algorithms to find out everything that happens while you're sleeping that you wouldn't be able to notice on your own.

Brain Sleep Coin (App)

The app incorporates a proprietary algorithm based on data accumulated through sleep research, and can analyze your sleep quality in various aspects. Not only can you improve the quality of your sleep based on the analysis results, but you can also exchange the "Sleep Coins" you earn by using the app for coupons for various products and services.

The app can be downloaded for free from the link below.

Brain Sleep Coin (Device)

The device is worn around the waist while sleeping and linked to the app, it can analyze important aspects of sleep quality such as sleeping posture, number of turns, and temperature inside the bed, which could not be seen with previous sleep measurement devices, in addition to the measurement items of the app alone. The silicone clip type is easy to put on and does not come off easily, and it is soft and comfortable, so it does not cause stress while sleeping.

*You can use the app alone for free, but by linking it to a Sleep Coin (device), the number of measurement items and accuracy will increase, allowing for more accurate sleep measurements.

Feature 1: Unprecedented sleep analysis

Using a proprietary algorithm based on sleep research and the technology used in sleep research, it reveals an individual's sleep stage (depth of sleep), sleeping position, bed temperature (temperature inside the futon), and snoring, which could not be seen with previous sleep measurement devices.

Feature 2: Supports comfortable sleep and awakening

The app includes high-quality music created in collaboration with Avex, such as the sound of rain, a bonfire, the sound of waves, and gentle healing sounds that will help you sleep well. By setting the sound when you fall asleep or wake up, it will help you fall asleep smoothly and wake up comfortably. The songs you can select will be added and updated from time to time.

In addition, by analyzing your sleep stages, the alarm can be set to sound when you are in a light sleep state, reducing the chance of you being woken up during a deep sleep and helping you wake up refreshed.

Feature 3: Earn coins every time you sleep

By performing various actions in the app, including sleep measurement, you can accumulate "Sleep Coins" in the app. The accumulated "Sleep Coins" can be exchanged for discount coupons for "Brain Sleep" products, in-app music purchases, in-app lottery tickets, and other valuable coupons and services. Various product coupons and services are updated from time to time, making sleep even more fun.

Golden Sleep Nose Mask [Pollen/House Dust]

This is a nasal mask that you wear inside your nose while sleeping to block the inhalation of pollen and house dust.

Feature 1: Anatomically designed to fit the human nose, protecting against pollen and house dust while you sleep

Anatomically designed to fit snugly over the nose, it blocks the inhalation of allergens such as pollen, mold, dust, pet dander, etc. Simply wear it over your nostrils, and you're free from suffocating nights caused by masks that block your mouth and nose.

Feature 2: Soft filter makes it comfortable to wear for long periods of time

It uses a soft, medical-grade material (filter) that is easy to breathe through, so it won't interfere with your breathing while you sleep.

It's very easy to use, just grab the bridge and push the front arm into the tip of your nostril and push the back arm back into the back of your nostril. It's also easy to remove, just grab the bridge and pull it out gently.

It comes in two sizes to suit the size of your nostrils (S size: 16-20mm, M size: 18-22mm), so it is comfortable to wear.

*Please use each one only once.
*It can be used day or night, but do not use it for more than 12 hours continuously per day.

Feature 3: It is not very noticeable, so you can wear it anywhere and at any time.

The transparent material makes it difficult to see, so you can wear it when you're out. It can be worn under a mask, and is also recommended for those who are concerned about makeup ruining or skin irritation caused by wearing a mask.

Combining a pillow and a mattress creates a synergistic effect!

Although you can achieve high-quality sleep just by using the "Brain Sleep Pillow" and "Brain Sleep Mattress Float" separately, using them together will bring you closer to a neutral posture, which is said to put less strain on the body, allowing you to achieve the ultimate relaxation posture. In addition, it increases the amount of heat dissipation compared to combining it with other materials, allowing excess heat to escape. For more information, please see the article below.

What are the benefits of using the Brain Sleep pillow and mattress together?

Brain Sleep Pillow Silent

Feature 1: The crown wave shape reduces snoring, promotes side sleeping, and regulates breathing.

The "Crown Wave" design supports side sleeping and prevents snoring when sleeping on your back. It is designed to be the optimal height for side sleeping, and the special core at the neck area firmly supports the neck and allows the head to sink in moderately to reduce strain on the neck.

Feature 2: Ultra-breathable material controls optimal sleep temperature and humidity

Like the Brain Sleep Pillow, the special material and shoulder support design allow for excellent heat dissipation, so heat does not build up. Compared to pillows made of urethane or feather material, the breathability is far superior, allowing you to sleep comfortably until morning.

Feature 3: Always clean by simply rinsing in the shower

The pillow itself can be washed at home, so you can sleep clean every day.

Brain Sleep Pillow Neck Fit

The new Brain Sleep Pillow Neck Fit is a pillow developed based on the idea of Seiji Nishino's book "The Stanford Way to Sleep Better." The ergonomic wave structure helps return the cervical vertebrae, which have been overworked during the day, to their correct position. It also stabilizes the chest, allowing you to sleep in a position that makes it easier to breathe.

Feature 1: Supports the shoulders and distributes the strain on the neck

Generally, the weight of the head is supported by the head and neck, but the shoulder support part supports the shoulders, distributing body pressure to three points: head, neck, and shoulders, reducing unnecessary strain on the neck. Although it is an affordable price range of 16,500 yen including tax, it fits the curve of the neck from the moment you sleep and gently wraps around the shoulders with just the right amount of firmness, so it is recommended for people who use their necks heavily during the day, such as for computer work or long hours of smartphone use.

Feature 2: Relaxes the muscles around the neck and shoulders

The neck suspension part maintains the wave of the cervical vertebrae and approaches the four muscles that support the neck. It relaxes the muscles around the neck and shoulders that are tense during the day. It is recommended for people who suffer from stiff shoulders and neck.

Feature 3: Supports natural turning over

The design is soft in the center and hard on the sides, which prevents your head from sinking when you sleep on your side. This keeps you in an ideal sleeping position even when you sleep on your side, and supports you turning over in your sleep, which is said to happen more than 20 times a night.

Feature 3: 4: 90% of the volume is air

It has excellent breathability, and even if you use it for a long time, it does not trap heat or humidity, and maintains a high heat dissipation rate. It prevents your head from getting stuffy, so you can sleep comfortably until morning. It can also be washed in the shower, so you can always keep it clean. It can be restored with hot water, so you don't have to worry if the pillow itself becomes worn out.

Brain Sleep Water Lemon Flavor

Feature 1: Japan's first triple functionality claim!

It was the first food in Japan to be certified with triple functional claims, due to its three benefits: "improving sleep quality," "relieving stress," and "maintaining memory."

Feature 2: Original complex of NMN, GABA (functional ingredient), and humus extract

Recent research has shown that NMN is a substance that can affect the decrease in sleep time that occurs with age, and it has been attracting attention in sleep research. It also contains GABA, which decreases in the body as we age, and humus extract. GABA is said to relieve stress, reduce fatigue, and improve sleep.

Feature 3: Healthy and easy to drink

It contains highly effective ingredients from the latest sleep research, uses natural water, and is additive-free, caffeine-free, and sugar-free. The subtle scent of Setouchi lemon extract makes it easy to drink even before bedtime.

Brainsleep Recovery Wear

This is recovery wear for sleep that incorporates the fatigue recovery properties of rare metals.

Feature 1: Unique recovery material "Medic Ge"

The fabric is treated with a special germanium formula [Medic Ge] that has a recovery effect. Germanium is a rare mineral and is counted as a rare metal. Also, unlike post-processing of the fabric, the germanium is kneaded into the fiber itself, so it will not wash away even if you wear it or wash it repeatedly.
(However, like regular fabrics, the fabric will deteriorate over time.)

Feature 2: Just by wearing it, you can improve your blood circulation and fully recover from fatigue.

Simply wearing it will improve blood circulation, ease muscle fatigue, relieve muscle stiffness, and recover from fatigue. You can recover well even with limited sleep time, and by conditioning your body, you can recharge your energy for the next day.

Feature 3: Relaxing design that doesn't cause stress

It is said that people turn over in their sleep about 10 to 30 times a night. Turning over has the effect of relieving pressure on the body parts during sleep and changing the air in the bed. This product has been designed to relax you by taking care of the stress caused by the necessary turning over.

This sleep-specific garment has larger armholes and minimal tightness from elastic and ribbing, so it doesn't get in the way of turning over while you sleep.

Feature 4: Eliminates the unpleasant stuffiness while sleeping

The original fabric is made by interweaving absorbent cotton and moisture-absorbing rayon with durable and quick-drying polyester yarn, which enhances moisture absorption and effectively prevents moisture, which is the enemy while sleeping. We have pursued the best combination of fibers for sleep.

Brain Sleep Pillow for Kids

This pillow has all the characteristics of the "Brain Sleep Pillow" but is made for children. The special material and unique structure give it the softness of a memory foam pillow and the bounciness of a high-resilience pillow. It's not too soft, not too hard, it's the perfect balance.

It has long been said that children who sleep well grow up well, but as digitalization progresses, the quality of sleep is getting worse. The amount and quality of sleep for growing children is very important not only for their minds and bodies, but also for the development of their brains.

Feature 1: Keeps the back and shoulders cool for children who have difficulty dissipating heat

Children's ability to regulate their body temperature is immature until puberty, so it is important to release heat properly in order to sleep soundly until morning. The Brainbow Kids Pillow is designed with excellent breathability to allow heat to be released from the back and shoulders.

Feature 2: Fits perfectly even with a growing body

The head part is soft and designed to sink in firmly, so it fits even the growing body. If the pillow becomes flat, you can restore the fluffy feeling by simply removing the cover and pouring hot water of 45 degrees or more over it.

Feature 3: Clean and sustainable

Because your pillow will be in contact with your skin for long periods of time every day, we are extremely particular about hygiene. We aimed to create a pillow that is easy to care for, stays clean, and is also environmentally friendly.

Brain Sleep Pillow Neck Fit

The new Brain Sleep Pillow Neck Fit is a pillow developed based on the idea of the best-selling Stanford Sleep Guide. Its ergonomic wave structure helps return the cervical vertebrae, which have been overworked during the day, to their correct position. It also stabilizes the chest, allowing you to sleep in a position that makes it easier to breathe. It has four features:

Feature 1: Supports the shoulders and distributes the strain on the neck

Generally, the weight of the head is supported by the head and neck, but the shoulder support part supports the shoulders, distributing body pressure to three points: head, neck, and shoulders, reducing unnecessary strain on the neck.

Brain Sleep Conditioning Studio

Brain Sleep Conditioning Studio is an acupuncture and massage store that specializes in sleep. Specialists with national qualifications in acupuncture and massage and knowledge of sleep provide treatments based on medical evidence. By regulating the autonomic nervous system, we aim to improve the quality of sleep from the day of treatment. In addition to treatments at the store, we also offer home care suggestions to help customers improve their condition in their daily lives.

A unique method to regulate the autonomic nervous system based on medical evidence

Feature 1: Acupuncture - Electric acupuncture leads to deep relaxation

Acupuncture is applied to areas that are expected to be effective in relieving stress, improving eye fatigue, and improving clenching of the teeth. Electric acupuncture increases alpha waves, enhancing the activity of the parasympathetic nervous system.

Feature 2: Moxibustion – Regulating internal organs that affect sleep

Moxibustion on the areas that regulate the stomach and intestines enhances the activity of the parasympathetic nervous system. It also increases the production of hormones that have a calming effect on the mind, which leads to improved quality of sleep.

Feature 3: Massage - Regulating breathing to give dominance to the parasympathetic nervous system

When breathing, the sympathetic nervous system is activated when you inhale, and the parasympathetic nervous system is activated when you exhale. Modern people tend to lose this balance and inhale more than they should. A massage that adjusts your breathing will help you get back to the correct rhythm.

Brainsleep Mattress Overlay

Feature 1: Layer it over your existing bedding to improve your sleeping comfort

By placing it on your existing bedding, you can improve your sleeping comfort. It cannot be used directly on the floor or on a worn bedding. It is very light and compact, so it is easy to carry.

Feature 2: Three-zone design that firmly lifts the waist and gently lifts the shoulders and legs

The mattress is designed with three zones of different densities to support the whole body in a balanced manner when lying down. It firmly supports the lower back, which supports about half of the body weight, to prevent sinking. It lifts the lower back firmly to create the correct sleeping position, so your body is aligned while you sleep.

Feature 3: Choose from four different hardness levels

Available in four sizes: single, semi-double, double, and queen. Each size is available in four hardness levels: soft (approx. 49kg or less), medium (approx. 50-74kg or less), hard (approx. 75-99kg or less), and super hard (approx. 50kg or more).

Generally, you choose the firmness of your mattress based on your weight, but if you sleep on your stomach, suffer from stiff shoulders, or prefer a gentle sleeping experience, we recommend a mattress one size softer. On the other hand, if you suffer from back pain, are elderly or lack exercise, or prefer a firm sleeping experience, we recommend a mattress one size harder.

This is recommended for people who want to easily improve the quality of their sleep, people who tend to wake up with sore lower backs due to their lower back sinking, and people who don't want to throw away their existing bedding.

Brain Sleep All-in-One

Feature 1: Mattress, pillow, and sleeping bag included in the set

This set includes a mattress, pillow, and the sleeping bag type "Brain Sleep Comforter," so you can get the best sleep anywhere with just this one item. Like the regular "Brain Sleep Mattress Float," the high-resilience fiber prevents your lower back from sinking. In addition, the three-gradation structure, with a soft center and hard sides, supports smooth turning over in bed.

Feature 2: The sleeping bag can be used in all seasons

In spring and summer, you can use it as a comforter by opening the zipper all the way, and in autumn and winter, you can use it like a sleeping bag by closing the zipper, so it can be used all year round. You can also leave the zipper closed and open only the foot part, so you can adjust the temperature comfortably even during the change of seasons.

Feature 3: It's 2/3 the size of a regular single bed, so it doesn't take up much space

Its compact size allows you to sleep comfortably even in a small space. You can also connect two of them together to use them as a 140cm double bed. When folded, it can be stored in a closet as it takes up 1/20 of its original size. It is useful not only for outdoor activities and when guests come over, but also in various situations such as disasters. It is recommended for those who are looking for compact bedding and those who want to focus on the quality of their sleep even in outdoor situations.

Brain Sleep Golden Sleep Pillow Mist

Pillow mist is a spray that you spray on your pillow or futon before going to sleep. It is a sleeping aid that allows you to easily enjoy the aroma by simply spraying it on without needing an aroma diffuser or humidifier.

The pleasant scent has a relaxing effect, making it a great gift for people who have trouble falling asleep.

"Brain Sleep Golden Sleep Pillow Mist" has a soothing woody scent. When you spray it on your pillows, sheets, and other bedding, it will envelop you in a gentle, refreshing scent, like forest bathing, creating a relaxing time.

It also has a disinfecting effect, so you can keep your pillows and sheets clean at all times.

Brain Sleep Pillow Cover

No matter how good your pillow is, if the pillowcase doesn't feel nice to the touch, you won't be able to sleep comfortably. Because it's something that touches your face directly, choose an item that is particular about quality and feel. Also, since pillowcases need to be washed frequently, it's recommended to have multiple pillowcases on hand. Simple colors like white and navy are popular.

Brain Sleep Pillow Cover Active Air

This pillow cover is packed with the latest high-performance technology, based on ultra-breathable material and cushioned mesh fabric. The world's first material, "COVEROSSRLIGHT," adds absorbent, quick-drying, antibacterial, and deodorizing properties, and is made of sustainable materials using recycled fibers with consideration for the environment.

Brain Sleep Comforter All Seasons

If you change your bedding with the seasons, you will need space to store the out-of-season bedding, so we recommend futons that can be used all year round.

The Brain Sleep Comforter All Seasons uses an innovative temperature control technology developed for space suits. The unique microcapsules change from solid to liquid in response to temperature changes, repeatedly absorbing, storing, and releasing heat.

It absorbs excess heat when it's hot and releases stored heat when it's cold, so it keeps the temperature inside the bed comfortable (33°C ±1°C). In addition, it has a reversible structure with a cool touch and a warm brushed material, so it can be used all year round, keeping you cool in the summer and as an inner blanket in the winter.

During seasonal changes and when there are drastic temperature changes between day and night, the quality of your sleep decreases and you accumulate physical and mental fatigue, so be sure to use a futon that will protect your body from temperature changes.

In addition, since the main unit can be washed completely, there is no need to put a cover on it, which saves you time and effort.

Brain Sleep Comforter Perfect Warm

Packed with Brain Sleep's knowledge and advanced technology , the Comforter Perfect Warm has the same moisturizing power as a down comforter , so you can spend a comfortable winter with just one.

1: 8-layer thermos structure that retains heat and prevents it from escaping

The first-ever 8-layer thermos structure keeps heat in, so you can get a good night's sleep.

The outermost layer is an insulating "aluminum protector." The inherent high heat retention of aluminum and its radiant heat technology keep the heat inside the futon in and keep out the cold air from the outside.

The heat-generating "Kapok Heat" in the middle part is the ultimate ethical fiber with an incredible hollowness and high heat retention. It is an innovative material that absorbs moisture and generates heat while being a sustainable plant fiber.

The surface that touches the skin is made of "Recovery Insulation", a fiber developed exclusively by Brain Sleep that is used in recovery wear. It uses rare germanium technology, which reflects heat using infrared rays to warm the body.

2: Warm yet thin and flexible, it fits the body well and doesn't leave gaps

The blanket fabric, which is closest to the skin, has a smooth cashmere-like texture. The blanket itself absorbs moisture and converts it into heat, making it very warm despite its thinness.

This futon does not require a blanket , so you don't have to worry about the blanket slipping off even if you turn over in your sleep. Also, the surface doesn't feel cold, so you can sleep comfortably.

3: No stuffiness! 

Down comforters have the disadvantage of being poorly breathable and prone to becoming stuffy, but the Comforter Perfect Warm absorbs and releases moisture, the enemy of sleep, and generates heat, providing exceptional warmth and a stuffy-free sleeping environment.

It can also be washed in your home washing machine, so you can always keep it clean.

Brain Sleep NMN 9000

In recent years, as "maintaining youthful energy" has become increasingly important in order to live a healthy and independent life, NMN has been attracting attention from researchers around the world. In the United States, research is being conducted using national budgets, and many papers on NMN have been published, with the number of reports increasing significantly since the 2000s.

In addition, although there has been progress in recent years in putting NMN to practical use, the reality is that many products are still expensive.

Brain Sleep has developed this product with the aim of improving brain performance, at an affordable price and in an easy-to-drink form.

Feature 1: Contains 9,000mg of NMN, the highest level in Japan

NMN can also be obtained from food, but to obtain 300 mg of NMN through food, you would need to eat 4,800 florets of broccoli, 144 liters of breast milk, or 24,000 edamame beans.

Brain Sleep NMN 9000 is condensed into just 3 tablets containing 300mg of NMN. Furthermore, we are thoroughly committed to the quality of the product, which is manufactured domestically and has a purity of over 99%.

Feature 2: Overwhelming cost performance in the NMN market

While containing high-quality NMN, we also paid particular attention to the price so that as many customers as possible can try it.

Feature 3: Brain Sleep original formula containing 20 other ingredients

In addition to NMN, it contains 20 types of base-up ingredients, including GABA, glycine, and theanine, which are said to be good for sleep.

[Development Story] Brain Sleep Comforter Perfect Cool

Feature 1: The four-layer structure makes you feel cooler when wearing it

Thanks to its four-layer structure consisting of a "cool layer" that feels cool to the touch, a "PCM layer" that maintains a cool feeling and controls a comfortable temperature, a "super cleansing layer" that is hydrophilic and can be washed thoroughly, and a "dry layer" that absorbs and diffuses water, you will feel cooler when wearing it than not wearing it at all.

Feature 2: Special microfiber yarn for ultimate coolness

There is a test method called "q-max" that is used as an index of coolness to the touch, and the higher the q-max value, the cooler it feels when it comes into contact with the body. The industry standard for "cooling bedding" is a value of 0.2 or more, with 0.3 being moderately cool, 0.4 being clearly cool, and 0.5 being surprisingly cool.

The Brain Sleep Comforter Perfect Cool is made using a special method in which a highly cooling polyethylene core is covered with cooling nylon. This involves twisting together approximately 100 fibers to form ultra-fine microfiber yarn, achieving the ultimate coolness with a tactile coolness value of 0.524 (q-max maximum heat absorption rate W/cm2).

The cooling fabric is made by utilizing the coldness of the fibers themselves, so the cooling effect of the fibers is not lost even after repeated washing, allowing for comfortable use for a long period of time.

Feature 3: Space technology PCM used for a cool feeling that lasts until morning

The duvet's filling contains microencapsulated PCM, an innovative cooling technology developed for space suits.

In general, sustained cooling bedding uses PCM printed on cooling fabric, which makes the fabric uneven and uncomfortable to the touch. To avoid this, some products have printing on the back side, but the fabric is still hard and uncomfortable to the touch.

The Brain Sleep Comforter Perfect Cool incorporates microencapsulated PCM into the Tencel filling material, which allows the fabric's texture to remain intact while restoring and maintaining the cool sensation when the comforter separates from the body due to tossing and turning during sleep.

Feature 4: Reversible structure makes it comfortable during the rainy season and hot summer months

It has a reversible structure, with one side made of cool-to-the-touch fabric and the other side made of absorbent, diffusing fabric, making it comfortable to wear during the rainy season and hottest months of the year.

Feature 5: Thoroughly cleans the inside of the futon

The insulation uses hydrophilic filling material. There is a high possibility that more mites are hiding inside the futon than on the surface, and the highly hydrophilic filling material can be thoroughly washed all the way to the inside.

Brain Sleep Premium Float Mattress
