A pillow that
supports deep sleep
and nurtures the brain

recommended height range: approx. 90–140 cm

Children’s sleep is deeply connected to brain and physical development.

When the brain develops, it not only supports learning-related abilities such as concentration, attention, and decision-making, but also plays a vital role in physical growth and emotional development.
Since sleep is very important, why not start by improving its quality?

Cooling the brain to support better sleep

Exceptional breathability × ice pack

Children’s ability to regulate body temperature remains underdeveloped until adolescence, making effective heat release essential.
The KIDS PILLOW combines exceptional breathability with an ice pack to release excess heat, supporting comfortable and restful sleep for children.

Cools from the back to the brain, for faster, deeper sleep

Children’s ability to regulate body temperature is still developing.
To sleep soundly through the night, releasing excess heat is essential.
Designed to dissipate heat effectively from the back, this pillow helps maintain a comfortable sleep environment for children who tend to overheat.

Deepen the sleep that defines your overall sleep quality — the “golden 90 minutes”

Brain sleep pillow was shown to have a higher proportion of deep sleep during the first sleep cycle (the “golden 90 minutes”), which plays a key role in determining overall sleep quality, compared with general functional pillows.

Perceived improvement in sleep quality

Compared with typical functional pillows, Brain Sleep pillow showed higher subjective evaluations related to alertness, sleep onset, and fatigue recovery.

High level of heat dissipation
prevents heat from accumulating

BRAIN SLEEP pillows feature a highly breathable material that retains significantly less heat than other materials, inducing high-quality sleep throughout the night.

Exceptional breathability
prevents moisture buildup

More than 90% of the structure is made up of air layers, allowing heat and moisture to escape rather than accumulate inside the pillow.
Compared with urethane or feather pillows, this design offers markedly superior breathability, maintaining a comfortable sleep environment through the night.

A specialized ice pack
that preserves breathability

Sized to avoid obstructing the pillow’s exceptional airflow, this ice pack remains comfortable even during sudden fevers or hot nights when cooling is needed.
Breathability is preserved throughout the night, ensuring a consistently comfortable sleep environment.

02Support a Growing Body

Gently support a growing body

A five-zone graduated structure—softer at the center and gradually firmer toward the edges—combined with a uniquely developed fiber that balances plush comfort and responsive support, creates a gentle, stable fit that adapts to a child’s growing body.

Smooth turning for children with less muscle strength

The five-zone graduated structure becomes more resilient toward the sides, supporting smooth turning during sleep—even for children with less muscle strength.
It allows children, who tend to turn over more frequently than adults, to move naturally and comfortably throughout the night.

03Super Clean

Easily washable under running water

It is said that the body perspires about one cup (approximately 200 ml) of sweat during sleep.
With its high excellent breathability, moisture is less likely to accumulate, and the pillow can be washed with water and dries quickly, allowing it to be kept clean at all times.
