Just by placing it on top of your existing bedding,
your sleep environment will change.
Just by placing it on topof your existing bedding,your sleep environment will change.
What's important for sleep
is not just the "quantity, but also the quality"
The wisdom of "Stanford Sleep: The Science of High-Quality Sleep"
is condensed within.
About one-third of our lives is spent sleeping.
If the quality of sleep is poor, your brain and body will not be able to rest, and
you will not be able to perform at your best.
Since bedding is an important item that you use every day, why not re-evaluate it from a quality perspective?
3-Zone Design
Wire Wave
Structure
With 3 zones of varying firmness and a
Wire Wave structure that lifts the body from within,
you'll feel lighter tomorrow.
Furthermore,
Lower your core body temperature
for a deeper "Golden 90 Minutes"
The quality of sleep depends on how deeply you can sleep for the first 90 minutes after falling asleep. If this golden 90 minutes is shallow, the quality of sleep will not improve, no matter how many hours you sleep afterward.
Our mattress, with its focus on breathability, lowers your core body temperature to induce a deeper sleep.
An incompatible mattress can
cause back and spinal pain.
When I wake up in the morning, my lower back hurts.
My body aches and I don't feel refreshed.
Too firm
Too soft
Heat gets trapped in the mattress, making it difficult to sleep.
Sinks too much,
putting a strain on the body.
Too soft /
Too firm
Difficulty turning over
Difficult to clean
(Cannot wash, moisture accumulates)
Dust mites and mold growth
Achieve optimal sleeping posture simply by layering it.
Feel lighter tomorrow.
When you wake up in the morning, do you have back pain or other body aches? This could be due to a mattress that is too firm or too soft. Our overlay instantly upgrades the support of your current bedding.
Our 3-zone design, with varying densities, is engineered to balance and support your entire body when you lie down. The lumbar region, which bears about half of your body weight, is firmly lifted to prevent excessive sinking.
Even though it's thin, it firmly supports the entire body from within the mattress and prevents excessive sinking, thus supporting an optimal sleeping posture.
Countless fibers support the body three-dimensionally from multiple directions, supporting all sleeping postures and body types.
Without burdening the body, it firmly supports the lower back to the buttocks, which are the heaviest parts of the body, and maintains a correct posture.
Test method: Measured from the shoulder as a starting point using a sleeping posture measuring device.
Properly supports the lower back and spine, allowing for smooth, energy-efficient tossing and turning.
Test method: Tossing and turning was repeated for 5 minutes at a rate of 60 times/minute. Respiratory metabolic rate was measured during this time, and the analysis used the average value over 3 minutes.
Made of over 90% air, it allows air to pass between the bedding and your body, releasing heat and moisture.
Simply placing it on your existing mattress makes it easier for air within the bedding to escape, allowing you to sleep comfortably until morning.
*Heat dissipation was measured over time with a sweating thermal mannequin set in an environment of 20°C and 65% humidity.
Typical mattresses cannot be washed, and accumulated moisture leads to the growth of mold and dust mites. Brain Sleep mattresses can be washed, and the material itself does not retain moisture, making it difficult for dust mites to breed, so you can always use it cleanly.
Test method: The thickness of the test piece was measured after repeated compression at a rate of 60 times per minute over 50% of its thickness, followed by 30 minutes of rest at room temperature, and the compression residual strain rate (sagging rate) was calculated.
Years of use: Calculated assuming 20 turns per night.

Not only can the cover be removed and machine washed, but the entire mattress core can also be washed.
The core can be easily maintained by simply rinsing off dirt with a shower and then air-drying in the shade.
Urethane and coil mattresses are prone to poor ventilation, accumulating moisture and heat, which can lead to dust mites and mold. Brain Sleep mattresses are highly breathable, making them less prone to dust mites and mold. Furthermore, they can be washed anytime you're concerned about household dust or dirt, allowing you to maintain a clean state.
Each mattress, pillow, and other product is meticulously checked for quality by engineers and craftsmen.
After strict quality inspections, each item is carefully packaged and delivered to the customer.
The spring water from Shimizu Bakuen, a special soft water designated as one of the "15 Famous Waters of Toyo no Kuni" with minimal impurities, is used in the production process. By using water with fewer impurities, unnecessary chemical reactions can be avoided, and quality deterioration can be prevented.
The cover features a large opening for easy removal and an internal piping design to prevent snagging. The side that touches the body has a soft brushed finish, and the side that overlaps with the bedding is made of a breathable mesh material to support comfortable sleep.
The Brain Sleep Mattress Overlay is a mattress designed to be placed on top of your existing bedding. It is recommended for those who are not satisfied with their current bedding or wish to change their sleeping comfort.
*It cannot be used directly on tatami mats or flooring.
*It cannot be used on severely sagging bedding (e.g., dented or wavy).
It is delivered compactly rolled into a cylinder for easy setup. Its lightness makes it easy for anyone to set up.
