Uniting the science of
the "brain" and "sleep"
Bringing BRAIN SLEEP technology
into one piece
Enjoy exceptional sleep
anywhere
A completely new bedding concept,
designed to enjoy sleep in a variety of settings.
For more comfortable, more fulfilling rest.
A first bed
for solo living
In a compact 6-tatami studio apartment in the city, a bed typically occupies approximately 1/4 of the total floor area, making a cramped living environment the norm.
BRAIN SLEEP ALL-IN-ONE is about 2/3 the size of a standard single bed.
When folded, it reduces the occupied area to approximately 1/20, creating a more space-efficient room.
A second bed
for new ways of sleeping
Suitable for a wide range of situations, including camping, overnight stays in the car, glamping, naps during work-from-home days, nights when quiet focus matters, guests, and for times of emergency.
Large, heavy bedding
may no longer be necessary.
Minimal,
new ways of sleeping.
Designed to pursue the distinctive comfort unique to BRAIN SLEEP, this all-in-one mattress focuses on sleep quality without compromise.
The BRAIN SLEEP PILLOW, which helps cool the brain and guide it toward deeper sleep, and the BRAIN SLEEP MATTRESS, known for its excellent pressure distribution, are combined into a single structure.
MATTRESS
With a thickness of 4 cm, the mattress delivers excellent pressure distribution, providing firm support for the lower back.
Compared with conventional urethane materials, the BRAIN SLEEP ALL IN ONE mattress releases heat more effectively, helping prevent heat buildup throughout the night and maintain a balanced bed microclimate.
PILLOW
Resilient fibers conform to the head and neck, helping maintain a comfortable sleeping posture.
The center is softly cushioned, while the sides are designed with firmer support.
This structure helps support the neck during side sleeping and adapts comfortably to both back and side sleeping positions.
Designed with sufficient width to allow comfortable turning during sleep, even for adults.
Enabled by a proprietary three-dimensional fiber structure, exceptional breathability helps prevent heat buildup and keeps the bed microclimate cooler during sleep.
COMFORTER
The lining that touches the skin is made from soft cotton.
The outer layer features a water-repellent material to help maintain cleanliness.
<Fall and winter>
With the zipper closed, it can be used like a schlaf bag, providing warmth during sleep.
Placing it on top of the mattress also helps block cold air from the floor.
<Spring and summer>
With the zipper fully open, it can be used as a comforter, allowing for easier temperature adjustment and comfortable use.
<Seasonal transitions>
By keeping the zipper closed and opening only the foot area, temperature can be adjusted while maintaining warmth within the bed microclimate.
Comfort temperature: 8°C
A temperature at which a standard female can sleep comfortably in a relaxed position.
Suitable for beginners to outdoor use as well.
Lower limit temperature: 4°C
A temperature at which a standard male can remain comfortable for 8 hours in a curled position.
Experienced outdoor users may achieve optimal thermal performance depending on clothing and other conditions.
The inner surface that comes into contact with the skin is made from 100% cotton, selected for its excellent moisture absorption and release.
Designed to save space, lightweight, and easy to carry.
Storage is simple and can be done one-handed, allowing for quick setup and pack-away in approximately 5 seconds.
A pocket exclusively designed for storing a smartphone is placed beneath the pillow.
Two units can be connected using the side zipper.
When joined, the width expands to 140 cm, comparable to a standard double bed.
The pillow and mattress can be rinsed in the shower.
The comforter and cover are machine-washable with water.
The pillow can be easily removed, allowing the pillow cover alone to be washed for convenient everyday care and lasting cleanliness.
The bottom and side panels are finished with a water-repellent treatment that helps repel water, sweat, mud, and dust.
