Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") will release the "Brain Sleep Comforter Perfect Cool Air Throw" (hereinafter "Comforter Air Throw"), a summer comforter that provides "ultimate coolness" and "super coolness" from bedtime to wake-up, even in the humid season when sleep problems increase. The comforter will be available on the Brain Sleep official website from May 14 (Wednesday). By adopting cooling fibers and a uniquely developed highly breathable Air Throw structure, the comforter achieves "ultimate coolness" through the double effect of contact cooling and sustained cooling. Furthermore, the reversible structure of ultimate cooling fabric and towel blanket fabric efficiently controls the humidity that causes restless summer nights, achieving "super coolness." Development Background 2023 and 2024 saw record-breaking heatwaves for two consecutive summers, and the Japan Meteorological Agency predicts that the summer of 2025 will also see nationwide temperatures higher than average.※1The arrival of midsummer days with temperatures reaching 30℃ or higher has been accelerating year by year, with observations typically made in April, but in 2025, this was observed at multiple locations nationwide on March 26.※2In recent years, in addition to temperature, the rise in humidity has also been significant, with the average humidity trend showing an increase of approximately 15% compared to 2004,※3and this outdoor humidity affects indoor humidity and, consequently, bedding humidity.※4Humidity and sleep quality are closely related, and a comfortable bedding humidity during sleep is said to be around 50%. In high-humidity environments, body heat cannot dissipate sufficiently, leading to increased night sweats and awakenings, and also increasing the risk of dust mites and mold, which cause allergies. Furthermore, while many people choose not to use comforters during muggy seasons, this can lead to excessive cooling and fatigue from direct exposure to air conditioning. Brain Sleep recommends using a comforter even during muggy seasons. Therefore, we developed a summer comforter that simultaneously controls high temperature and high humidity, providing "ultimate coolness" and "super coolness" that lasts until awakening, promoting restful sleep. ※1 Japan Meteorological Agency "Explanation of 3-month forecast (announced April 22, 2025)"※2 tenki.jp [Breaking News] First midsummer day nationwide this year - First midsummer day in March in 26 years https://tenki.jp/forecaster/deskpart/2025/03/26/33032.html※3 From Japan Meteorological Agency "Past Weather Data" (Calculated average humidity in Tokyo during the 3-month period from June to August for each year from 2004 to 2024)※4 Fukumi Maki, Tsutomu Aoki "Journal of the Japan Wood Research Society Vol. 52 No. 1 Changes in Humidity in Various Living Spaces" Makuake Supporter Feedback Following the previous Makuake project "Brain Sleep Perfect Cool" series, many supporters have expressed their anticipation for the "Comforter Air Throw" for this summer, which is expected to be even hotter.・I'm looking forward to spending the increasingly hot and restless nights a little more comfortably with the help of bedding.・I hope to get through the hot summer refreshingly. I'm happy about the towel blanket side.・Last winter's Comforter Dual was much better than I expected, and the feel of the fabric, in particular, improves sleep comfort. Since this one is also reversible, I have high hopes for its feel. Features of "Brain Sleep Comforter Perfect Cool Air Throw" 1.PERFECT COOL & REVERSIBLEUltimate coolness lasting until morning and reversible designThe reversible design with a cool side that achieves ultimate coolness through the double effect of contact cooling and sustained cooling, and a towel blanket side, supports comfortable sleep.[Contact Cooling]260% cooling sensation! Experience ultimate coolness with our uniquely developed cooling fiber!We uniquely developed yarn and fabric from scratch in pursuit of ultimate coolness, achieving a contact cooling Q-MAX value of 0.524 (Q-MAX maximum heat absorption rate w/m²), which is approximately 260% of the standard value of 0.2. This ultimate cooling fabric effectively absorbs heat upon contact, providing a cool sensation, and its functionality does not degrade with washing.[Sustained Cooling]Coolness lasting all night with space technology PCM*The filling fibers are blended with microencapsulated PCM, an innovative cooling technology developed for spacesuits. While conventional contact-cooling bedding loses its cooling properties once heat absorption reaches saturation, the Air Throw's cooling sensation regenerates and is maintained as the body moves away from the comforter during sleep (e.g., turning over).*PCM stands for Phase Change Material 2.PERFECT DRY & COMFORTSuper coolness with a uniquely developed Air Throw structure. A comfortable sleeping environment.The unique Air Throw structure eliminates uncomfortable humidity during sleep. A special structure with air ventilators (mesh) on both sides allows air to circulate and control humidity during sleep. Both the cool side and the towel blanket side absorb and release moisture, achieving a comfortable, breathable humidity within the bedding.Compared to conventional down blankets, breathability is significantly improved. By using a highly breathable material, it circulates air during sleep to eliminate humidity. 3.PERFECT CLEANThoroughly cleans the inside of the comforter for perfect cleanliness without a coverIt can be used without a cover and is fully machine washable at home, so there's no need to worry about dirt, mold, house dust, or mites inside the futon. Cleanliness is maintained even without a cover.
