Each one is made with care using patented technology and skilled craftsmanship.

AWAKEN

01Cool your brain

Cool your brain for
faster, deeper sleep.

Over 90% of the pillow consists of an air layer, preventing heat and humidity generated during sleep from accumulating and creating a comfortable sleep environment.

Deepen sleep
during the "Golden 90 Minutes"
that determines sleep quality.

The Brain Sleep Pillow has been 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 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 about the evidence

Realize an improvement
in sleep quality

The Brain Sleep Pillow was confirmed to have higher subjective evaluations regarding drowsiness, sleep onset, and fatigue recovery compared to general functional pillows.

High heat dissipation,
no heat buildup

Heat buildup can affect sleep quality.
This product is made of a highly breathable material, so it prevents heat buildup more effectively than other materials, allowing you to sleep comfortably all night long.

02Personalized fit

Patented technology creates your
personalized pillow with a
3-layer, 9-gradient structure

Our patented technology creates a 3-layer, 9-gradient structure that gradually conforms to the size and sleeping position of your head.
With each use, it becomes your unique pillow, optimized for sleep.

A new sensation that
surpasses custom-made:
the ultimate fit

Countless fibers act as springs, creating a new sensation of elasticity that is both bouncy and softly envelops your head.
Adjustment Layer: Softly and gently conforms to the shape of your head.
Support Layer: Firmly supports your head and neck.
Base Layer: Hard, allowing air to escape from below.
Additionally, its 3-layer structure combines surface softness with durability for daily use.

Fits you with every use,
reducing stress on your head and neck

Test method:
Head pressure distribution measured after 1st use and after 1 week.
Subject:
Male, 169 cm tall, 62 kg in weight.

Supports any sleeping posture

The elasticity increases towards the sides, preventing the head from sinking too deeply when sleeping on your side, maintaining your sleeping posture. It adapts to any sleeping position, whether on your side, stomach, etc.
The 9-gradient structure also supports smooth turning in bed.

03Super Clean

Washable with a shower for cleanliness

It is said that humans sweat about one cup (approx. 200 ml) during sleep.
With excellent breathability, it prevents moisture buildup and is hygienic. Furthermore, it's washable and dries quickly, so you can always keep it clean.

FAQFrequently Asked Questions

What to do if the pillow height feels wrong

We recommend maintenance every 1-2 months by following the 3 steps below.
STEP1: Pour hot water at 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.
Do not pour hot water while the pillow is propped up or under pressure, as this may cause deformation.

STEP2: Pour cold water for about 15 seconds to fix the fluffiness.
Tap water temperature is fine.
*During extremely hot summer days, the effect may be diminished as tap water temperature rises.

STEP3: Dry in a well-ventilated, shaded area.
Place the pillow flat to dry.
Avoid direct sunlight or drying with hot air.
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 do I clean it?

If you are concerned about odors or stains
The pillow cover is machine washable. Please check the washing instructions. The pillow itself is washable.
Rinse it with lukewarm water (around 40 degrees) from the shower.
After rinsing, dry it in a shaded, well-ventilated flat area.
If you are particularly concerned about odors or stains, use a diluted neutral detergent.

Precautions when cleaning the pillow body
Please note that bending or applying pressure to the pillow may cause creases or depressions.
When cleaning, do not use hot water above 51 degrees. Also, continuous exposure to direct sunlight will degrade the quality.
Avoid drying in direct sunlight and always dry in the shade.

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

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

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

Set the pillow with the mesh side of the pillow cover facing down and the firm side of the pillow facing up. After tucking in and adjusting the flap of the pillow cover, flip the pillow upside down and use it.
*Please use the pillow with your head resting on the mesh side.
