Sleep is not just about time. It’s about quality The only mattress that brings 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? What matters in a mattress comes down to two aspects of body control. Posture×core body temperature The ultimate relaxed posture Designed to recreate the posture identified by NASA as placing minimal strain on the body Designed for the ultimate relaxed posture FLOATTECHNOLOGY Patent No. 7727279 A proprietary float structure that supports the legs, waist, and shoulders This structure enables a neutral sleeping posture and effective body pressure distribution, helping reduce physical strain during sleep. Advanced pressure distribution A three-layer structure supports the body from multiple directions, facilitating smooth movement during sleep.A foldable two-way design allows for compact storage. In addition, Lowering core body temperaturefor deeper “golden 90 minutes” Sleep quality is largely influenced by the depth reached during the first 90 minutes after falling asleep.When this “golden 90 minutes” remains shallow, longer sleep alone does not necessarily improve quality.This BRAIN SLEEP mattress, designed with breathability in mind, helps lower core body temperature, guiding sleep toward greater depth. Drawbacks of a typical mattress Difficult falling asleep due to heat buildup in the mattress Excessive sinking can place strain on the body Too soft / too firm Restricted turning during sleep Difficult to care for (not washable, moisture tends to build up) Dust mites and mold can develop Common issues caused by an ill-fitting mattress Waking up still feeling tired, even after a full night’s sleep Feeling fatigued from the moment the day begins An uncomfortably warm and humid sleep environment Lower back pain and shoulder stiffness Waking up during the night It is said that sleep is said to makes up one-third of our lives.Why not take a fresh look at the mattress — one of the most important elements of quality sleep? One change can transform sleep TECHNOLOGY 01Float technology designed to reduce physical strain 02A super-breathable material designed to guide sleep toward greater depth 03Fully washable with water, for cleanliness from the core 01Float technology Recreating the neutral posture identified by NASA Astronauts have noted that resting in space feels more comfortable than on Earth.When the body is freed from gravity, the shoulders naturally settle inward and the legs rise slightly—forming a posture considered to place minimal strain on the body.Float technology recreates this neutral posture. Through its unique three-dimensional structure, it provides balanced support tailored to the shoulders, lower back, and legs, creating a floating sensation while maintaining optimal firmness.This design encourages a deeply relaxed posture, easing the body away from gravitational load. A deeply relaxed posture supported through the legs, lower back, and shoulders Leg float Elevates the legs to support circulation in the body Lumber support Three layers of high-resilience fiber provide stable lumbar support Shoulder rest Supports a posture that allows easier breathing View detailed evidence Relaxation of the body and mind This product creates a posture that supports deeper, more comfortable breathing.By shifting brain activity toward an alpha-wave–dominant state, it helps guide both the body and mind into a relaxed state. A sleep posture that minimizes physical strain Mattresses made from soft materials such as urethane may feel comfortable due to their plushness, but in practice, excessive sink depth can place strain on the body during sleep.By using a high-resilience material, this product minimizes sink depth and supports a sleep posture close to a neutral position—often described as the ideal posture for deep relaxation. Superior pressure distribution and high resilience The material used in this product features a three-dimensional structure formed by interwoven, tube-shaped elements with high resilience.By adapting to the contours of the body, countless coil-like structures provide support from multiple directions, allowing pressure to be distributed evenly across the surface. Elevating the legs supports circulation and recovery The leg section is designed to sit 4 cm higher than the chest, encouraging smoother blood flow back toward the upper body. This positioning helps ease feelings of fatigue and swelling. View detailed evidence Blood circulation increases by approximately 150% In a comparison between a flat mattress and this product, which features an elevated leg-rest structure, blood flow volume increased by approximately 1.5 times.This increase is believed to help alleviate fatigue and swelling. Supports smooth turning during sleep The lumbar area, which bears the greatest pressure, is designed with a higher-density structure to provide stable support throughout sleep.By reducing excessive sinking at the lower back, the design allows for smoother turning during sleep, offering comfort even for those who are mindful of lumbar support. Zoned support tailored to different body areas helps maintain an ideal sleeping posture A wire-shaped support core, “Wire Wave,” features fibers of varying thickness designed to correspond to different areas of the body, supporting the body from within the mattress.By accommodating differences in body pressure across each zone, it prevents excessive sinking and helps maintain an ideal sleeping posture. 02Super breathable Controls temperature and humidity for optimal sleep through super-breathable materials To achieve quality sleep, maintaining proper temperature and humidity within the sleep environment is essential.With over 90% of its structure composed of air layers, heat and moisture generated during sleep do not build up, creating a consistently comfortable sleeping environment. View detailed evidence Lower surface temperature rise compared to other materials Sleep quality is largely influenced by the depth reached during the first 90 minutes after falling asleep. Lowering core body temperature supports deeper sleep, while heat buildup prevents body temperature from dropping, making it harder to fall asleep.With its highly breathable structure, the BRAIN SLEEP mattress shows a lower rise in surface temperature compared to other materials, contributing a smoother transition into sleep. High level of heat dissipationprevents heat from accumulating The BRAIN SLEEP mattress features a highly breathable material that retains significantly less heat than other materials, inducing high-quality sleep throughout the night. 03CLEAN FOR LONG TIME & DURABILITY Washable with water for lasting cleanlinessMites and household dust are less likely to accumulate Shower-washable for easy cleaning—simply rinse with water and allow to dry in a well-ventilated area. Maintenance is simple and hassle-free.Mattresses made of urethane foam or coils tend to trap heat and moisture due to limited breathability, creating an environment where dust mites and mold are more likely to grow.In contrast, the BRAIN SLEEP mattress features excellent breathability, making it difficult for dust mites and mold to develop, as well as being washable with water to help maintain a consistently clean sleeping environment. View detailed evidence Minimal mold growth Compared to other materials, this product shows a significantly lower level of mold growth.It is also recommended for those sensitive to house dust or allergies, as well as for families who sleep with young children. Outstanding durability, equivalent to 80,000 uses Everyday use makes durability a key concern when choosing a mattress.This product has demonstrated high durability through compression testing equivalent to 80,000 cycles, in accordance with JIS standards.Even with long-term use, it continues to deliver stable comfort.*Durability may vary depending on usage conditions. MADE IN JAPANMeticulous craftsmanship,trusted quality Each mattress and pillow is carefully crafted, with skilled technicians and artisans conducting repeated quality checks by hand.After passing rigorous inspections, each item is meticulously packaged and delivered with care. Natural spring water with minimal impurities is used to prevent quality degradation The production process uses natural spring water from Shimizu Bakuen, designated as one of Toyonokuni’s 15 Famous Waters—a special soft water with exceptionally low levels of impurities.By using such pure water, unnecessary chemical reactions are avoided, helping to prevent any deterioration in quality. SCENES Use it on your existing bedding—or on its own The Float Mattress is designed with a firmer base layer where it meets the bed or floor, ensuring stable comfort regardless of how or where it is placed.It can be placed on top of an existing mattress or futon, or used directly on flooring or tatami—adapting naturally to a wide range of living spaces.With ample resilience, the mattress provides comfortable support even when used on its own, making it suitable both for everyday use and for accommodating overnight guests.
