Recreates the neutral posture advocated by NASA
for ultimate relaxation

When you rest your body in space, your shoulders naturally tuck in and your legs rise. This is said to be the posture that
puts the least strain on the body. This product's unique three-dimensional structure creates a floating feeling and the perfect firmness for your shoulders, hips, and legs, encouraging you to achieve the ultimate relaxed posture free from gravity.

Lifting 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.

Maintain an ideal sleeping position
with zoning support for different parts of the body

The wire-shaped support core "Wire Wave" with fiber thickness adjusted according to the part of the body supports the body with lines from the inside of the mattress. It supports the parts of the body with different body pressure, and keeps the ideal sleeping position without sinking too much.

Ultra-dispersion of body pressure helps you turn over in your sleep and helps
you rest your body while saving energy

By sleeping in the correct posture, you can turn over smoothly without strain. In addition, the 7-layer structure that repeatedly absorbs and rebounds as you turn over supports you. By minimizing energy consumption while sleeping, you can reduce strain and sleep comfortably until morning.

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.

Dissipates body heat and sweat,
maintaining a comfortable sleeping environment until morning

Made from ultra-breathable material, this product releases heat caused by rising body temperature while you sleep and moisture caused by night sweats, keeping your bed comfortable while you sleep.

Test method: The subject lay down on the mattress for 20 minutes, covered with a towel blanket, and rested. Thermography was used before and after lying down (before use began/after 20 minutes had passed).

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

Not only can the cover be removed and washed in the washing machine, but the mattress's inner material is also washable.

The inner material can be washed off in the shower, and after the shower, it's easy to dry it in the shade.

Urethane and coil mattresses have poor breathability and tend to accumulate moisture and heat, making them prone to the growth of dust mites and mold. Brain Sleep mattresses are breathable, making them less susceptible to the growth of dust mites and mold, and can be washed at any time if you notice any house dust or dirt, so they can be kept clean.

When it comes to mattresses that you use every day, one thing you care about is their durability.
This product has proven to be highly durable, even when compressed 80,000 times according to the JIS standard. It provides a stable sleeping experience even after long-term use.
*Durability may vary depending on how it is used.
