A mattress that changes how you wake up with
an ideal sleeping posture x super pressure distribution

Recreating NASA's
neutral body posture
for ultimate relaxation

When you surrender your body in space, your shoulders naturally turn inward and your legs lift. This is considered the posture with the least strain on the body.
This product uses a unique three-dimensional structure to create a floating-like rebound and optimal firmness tailored to your shoulders, lower back, and legs, promoting an ultimate relaxed posture free from gravity.

Ultra pressure distribution supports turning over
Rest your body with low energy consumption

Sleeping in the correct posture allows for smooth and effortless turning. Furthermore, the 7-layer structure, which repeatedly absorbs and repels in response to turning, supports the act of turning over. By minimizing energy consumption during sleep, it reduces strain and allows for comfortable sleep until morning.

Ultra-breathable material
Controls optimal temperature and humidity
for sleep

To achieve quality sleep, it is important to maintain appropriate temperature and humidity within the bedding.
With over 90% air pockets, heat and moisture generated during sleep do not accumulate, creating a comfortable sleeping environment.

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

This ultra-breathable product dissipates heat from rising body temperature and moisture from sweat during sleep, keeping the sleeping environment comfortable.

Test method: A subject lay on the mattress for 20 minutes with a towel blanket. Thermographic images were taken before and after lying down (before use / after 20 minutes).

Clean with a shower
Less dust mites and house dust

The cover is removable and machine washable, and all the core materials of the mattress can also be washed.

The core material can be easily rinsed clean with a shower, and then simply air-dried in the shade.

Urethane and coil mattresses often have poor breathability, leading to accumulated moisture and heat, which encourages dust mites and mold. BRAIN SLEEP mattresses have excellent breathability, preventing dust mites and mold, and can be washed anytime if house dust or dirt is a concern, maintaining a clean state.

Excellent durability
Can be used for 10 years

For a daily-use mattress, durability is a key concern.
This product has demonstrated high durability even after 80,000 compressions according to JIS standards. Consistent comfort continues even with long-term use.
*Durability may vary depending on usage.
