Sleep is not just about time.
It’s about quality
Bringing together the full science of
The Stanford Method for Ultimate Sound Sleep.
We spend nearly a third of our lives asleep.
When sleep quality is poor, the brain and body do not fully rest, making it difficult to perform at their natural best.
Because sleep products are part of our everyday lives, why not reconsider sleep from the perspective of quality?

TECHNOLOGY
01AIR THROW STRUCTURE
Air throw structure
regulates heat and humidity
Maintaining appropriate temperature and humidity within the sleep environment is essential for quality sleep.
The air throw structure promotes air circulation, allowing heat and moisture generated during sleep to dissipate and helping maintain a comfortable sleep environment.
By enabling continuous vertical airflow, the structure consistently supports optimal ventilation throughout the night.
Enhanced breathability when paired with a BRAIN SLEEP mattress
This bed frame is designed to work in combination with a BRAIN SLEEP mattress, maximizing breathability without compromising performance.
By supporting the mattress’s structure—composed of over 90% air layers—it allows airflow to function as intended and brings out the mattress’s full potential.
Provides stable support for the mattress
to create an ideal sleeping posture
The slat spacing is carefully designed to optimally support both the mattress and the body.
Appropriate slat width and spacing, combined with the natural softness of Hinoki wood grain, provide support without placing excessive stress on the mattress or the body.
02MATERIAL Hinoki
Japanese Hinoki creates a comfortable sleep environment
Hinoki cypress sourced from Shimane Prefecture—an area long known for producing quality timber used in traditional architecture such as Izumo Taisha, Mt. Sanbe, and Matsue Castle—is used for this bed frame.
Only untreated Hinoki is used, without additional coatings or finishes, allowing the wood’s natural benefits to be fully expressed.
Effective humidity regulation
Hinoki wood absorbs and releases moisture according to room humidity, maintaining a comfortable sleep environment.
Relaxation and stress reduction
Hinoki naturally contains α-pinene, an aromatic compound known for its calming qualities.
When inhaled, it is said to promote relaxation of both the mind and body and to ease stress.
Because this bed frame is made from untreated Hinoki, its natural aroma gently spreads throughout the bedroom, creating a relaxed atmosphere that supports restful sleep.
Antibacterial, deodorizing, and odor-control benefits
Hinoki contains natural components that are known to inhibit bacterial growth and break down odor-causing substances.
Protecting the environment through the sustainable use of forest resources
To preserve natural ecosystems, thinned wood generated through forest management is utilized—trees selectively removed to support healthy forest growth.
Among these materials, smaller-diameter trees aged approximately 10–20 years are specifically selected. Such trees are often difficult to use in construction or furniture production and are therefore frequently discarded or incinerated.
By repurposing these underutilized resources, a responsible and cyclical use of forest materials is achieved while reducing environmental impact.
03FIT YOUR LIFE
Adjustable size to suit changing lifestyles
The needs of daily living evolve over time—shaped by growth, work, and changes in family structure.
The bed frame is designed to adapt to these transitions, supporting a flexible and more sustainable way of living.
Easily expandable from single to double
A size-shift structure that can be adjusted easily with one hand.
There is no need to replace the bed frame each time life stages or lifestyles change.
By using a bed frame one size larger than the mattress, the extra space can also be used as a side table.
Low, middle, or high—height adjustable to suit your preference
Many people sleep with their mattress placed directly on the floor or use a futon.
However, adjusting the height of the bed is also an important factor in creating a comfortable sleep environment.
High (18 cm) and Middle (9 cm) leg options are available for ¥11,000 each (tax included).
Choose the height that fits your lifestyle
A height of 30 cm or more is recommended to reduce exposure to house dust.
The area within 30 cm of the floor is often referred to as the “house dust zone,” where dust tends to circulate more easily.
For those sensitive to dust or allergies, sleeping at a height of 30 cm or higher is recommended for a cleaner sleep environment.
Recommended combinations for a total height of 30 cm or more
・Low legs × Premium Float or Plus Float
・Middle legs × Premium Float / Plus Float / Float
・High legs × Premium Float / Plus Float / Float
A height of 40 cm or more is recommended to reduce strain on the legs and lower back.
When seated on the edge of the bed, this height allows the knees and hips to form a 90-degree angle, with the feet resting flat on the floor.
This posture makes it easier to stand up and helps reduce strain on the legs and lower back.
Combinations that reach 40 cm or more
・Middle + PREMIUM FLOAT
・High + PREMIUM FLOAT or PLUS FLOAT

About the wood grain of Hinoki
During the processing of Hinoki—particularly around knots and knot-adjacent areas—natural variations such as those shown in the photos may occur.
These are inherent characteristics of natural wood and do not affect the strength or durability of the product.
Because natural Hinoki is used, resin may occasionally appear on the surface after delivery or during use.
This resin is a natural substance that gives Hinoki its distinctive, pleasant aroma and indicates the wood’s healthy, living character.
If resin appears, gently wipe it away with a cloth lightly dampened with ethanol or vinegar.

FAQFrequently asked questions
How should I care for the product?
[Daily care]
Because wood absorbs moisture, mold may develop in high-humidity environments. If the room temperature or humidity is high (conditions favorable for mold growth are approximately 20–28°C and 75% humidity or higher), ensure adequate ventilation. If the indoor environment becomes hot and humid, remove the mattress from the bed frame and allow air to circulate
[If stains are a noticeable]
Clean the surface using a dry cloth.
Do not use chemical wipes, alcohol-based cleaners, benzine, thinner, bleach, shoe polish, or similar products.
If dry wiping does not remove the stain, lightly sand the affected area with fine sandpaper (#240 grit or finer), taking care not to over-sand.
[If mold appears]
Choose a dry day with good airflow and allow the product to dry thoroughly in a shaded, well-ventilated area.
Next, gently wipe the mold away using a dry cloth lightly moistened with 70% ethanol, then allow the surface to dry completely.
Please note that discoloration caused by mold cannot be removed.
Can Hinoki wood crack?
Cracking is more likely in very dry environments or when the product is exposed directly to airflow from heating or air-conditioning systems, regardless of the length of use.
To reduce the risk, please observe the following:
・Avoid long-term placement in high-humidity or extremely dry conditions, as repeated expansion and contraction may cause warping, cracking, or discoloration.
・Avoid exposure to direct sunlight, strong lighting, or hot air from heaters, stoves, or air conditioners, which may lead to deformation, cracking, discoloration, or potential injury.
Can I assemble the bed frame by myself?
Assembly by two or more people is recommended.
Before starting, carefully review the included assembly instructions and confirm that all listed parts and hardware are present.
