Brain Sleep’s customer service desk receives many inquiries every day, and among them, the most common is about “how to care for the Brain Sleep Pillow.” Therefore, we’d like to introduce recommended care methods to help you use your Brain Sleep Pillow comfortably for a long time!
Wash it at home with water once every 1-2 months!

While the Brain Sleep Pillow resists dirt and flattening, you can wash it with water whenever you want to clean it or if you start to notice any flattening.
Easy to clean with a shower, so it’s always hygienic!
The pillow itself can be hand-washed.
Because it's made from woven polyethylene, dirt is unlikely to seep in and become impossible to remove. You can easily wash away dirt by simply rinsing it with a 45-50 degree shower. After thoroughly draining the water, air dry it in a well-ventilated, shaded area. It will dry in about 30 minutes if dried in a well-ventilated place.
The guideline for care is once every 1-2 months, but if you are concerned about dirt or odor, washing it frequently will allow for more comfortable use.
Wash at 39 degrees or less to maintain the custom fit!
The Brain Sleep Pillow is characterized by its ability to change shape and fit the user's head shape and weight. Since the pillow retains the shape it had before use, washing it with hot water at 45-50 degrees will restore its fluffy fullness.
This means that if you wash it with water at 39 degrees or less, you can clean it without losing the personalized, custom-made fit.
The Brain Sleep Pillow can be easily washed at home, keeping it clean and comfortable at all times. Since the pillowcase is machine washable, even busy people can enjoy a clean and comfortable pillow that can help turn their daily sleep into a restorative recovery period.
Made of polyethylene, so no need to fear dust mites or mold!
Since pillows are used for long periods every day, it's essential to keep them clean. In particular, the proliferation of dust mites and mold can cause skin irritation, allergies, and asthma, so careful maintenance is necessary. However, if dust mites and mold are inherently less likely to occur, you should be able to maintain cleanliness with less frequent care.
Therefore, Brain Sleep conducted its own study to determine the number of dust mites and mold in the entire pillow at different usage frequencies for the Brain Sleep Pillow (made of polyethylene), and pillows commonly used with urethane and feather materials. Let's compare the results right away.
The Brain Sleep Pillow has a significantly lower incidence of dust mites and mold compared to other materials.

The research results showed that feather materials are prone to dust mites. Regarding mold, both urethane and feather materials were prone to its growth, while the Brain Sleep Pillow, made of polyethylene, had a significantly lower incidence of dust mites and mold compared to other materials.
It is important to sleep on clean bedding, especially when you are recovering from a day's fatigue and breathing deeply unconsciously. This is especially recommended for those with house dust or allergies, and for those who sleep with children.
A 100% recyclable material, rare in bedding
Polyethylene, a material that is less prone to dust mites and mold, is also characterized by being a sustainable material that considers the global environment, with 100% of manufacturing scraps and items collected for size exchange being reused. It's also a great benefit that by using the Brain Sleep Pillow, you can effortlessly participate in sustainable activities.
If you start to notice some flattening
While the Brain Sleep Pillow can regain its fluffiness, there's one thing I'd like to tell you beforehand.
The Brain Sleep Pillow is a three-layer pillow with nine gradients, designed with a strong focus on fit. A characteristic of the pillow is that its shape changes to conform to the shape of your head, so it might not be flattening, but rather a sign that it has adapted to your head.
Therefore, it is recommended to check the actual fit when you lie down, rather than just the visual change, to determine if it has flattened. See the article below for the secret to its fit.
The Secret to the Brain Sleep Pillow's Beyond-Customized Fit
If you still want to restore its fluffiness, the following method is recommended:
Spray with 45-50 degree shower water
Spray 45-50 degree shower water onto the entire pillow for about 3 minutes, focusing on the area where your head rests, and it will regain its fluffiness. You can also wash it completely at the same time, killing two birds with one stone! Afterwards, drain the water thoroughly and air dry in the shade.
*Please note that spraying hot water above 51 degrees can lead to a deterioration in quality.
Since body types and muscle development change daily, if you feel that the pillow's shape no longer fits you or if you are concerned about the Brain Sleep Pillow's flattening, please try this method.
Achieve higher quality sleep with the Brain Sleep Pillow!
Sleep is said to have various effects, such as resting the brain and body to recover from fatigue, consolidating memories, regulating emotions, and balancing the autonomic nervous system. Although it may be difficult to dedicate a lot of time to sleep in today's busy lifestyle, improving the quality of sleep can activate the brain and enrich the five senses, so please consider focusing on sleep quality.
Aim for higher quality sleep with the Brain Sleep Pillow, which is easy to keep clean as it can be fully washed, and is less prone to dust mites and mold!
