Brain Sleep Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") will launch the "Brain Sleep Comforter Perfect Warm" (hereinafter "Perfect Warm"), the ultimate winter duvet that recorded 100 million yen, the highest amount ever* in the bedding category of Makuake, a crowdfunding service for new products and experiences. The first general sale of "Perfect Warm" will begin on October 10, 2023 (Tuesday) at the Brain Sleep Store. In 2022, "Perfect Warm" received crowdfunding far exceeding expectations on Makuake, leading to the cancellation of its planned general sale and remaining a Makuake-exclusive product. Due to numerous requests for purchase, we will begin its first general sale in 2023. This ultimate duvet, which offers ultimate warmth, comfort, and cleanliness, will ensure comfortable sleep in winter. *As of September 7, 2023, based on our own research The importance of seasonal sleep environment, a duvet to prepare for winter sleep This summer, unusually extreme heat prolonged worldwide, significantly updating the highest global temperatures on record. In Japan, the lingering summer heat continued, with the average temperature in September exceeding the normal year by more than 2℃, and the Japan Meteorological Agency announced that it was the highest in the 125 years since statistics began, causing a deterioration in the sleep environment due to unexpected heat, leading to restless nights and affecting sleep quality. Seasonal measures are crucial for the sleep environment, and it is necessary to prepare for winter sleep before the season when temperatures and humidity drop the most throughout the year. In winter, as a measure against "cold," attention is often paid to indoor temperature control, such as warming the bedroom with an air conditioner before bedtime. However, bed temperature and humidity are also very important for sleep quality. A study on the bed environment and sleep quality showed that while bed temperature tends to decrease with room temperature in the morning, keeping the bed temperature constant at 33℃±1, which is considered to improve sleep quality, shortened sleep latency (a measure of falling asleep) by 15.8 minutes and increased the percentage of deep sleep relative to total sleep time by 4.3%, compared to not maintaining the bed temperature. "Perfect Warm" features materials and a structure developed to maintain ideal bed temperature and humidity from bedtime to waking. Since winter is a season prone to infectious diseases, including those caused by dryness, Brain Sleep aims to improve the sleep environment by optimizing temperature and humidity without over-relying on air conditioners or heaters, thereby enabling high-quality sleep.

Features of "Brain Sleep Comforter Perfect Warm" 1. Ultimate warmth far surpassing down duvets The "8-layer thermos structure" incorporates Brain Sleep's wisdom and advanced technology. Advanced technological materials that generate heat, insulate, and reflect heat are layered. Furthermore, the 8 layers retain heat, preventing warm air from escaping. Simply by using one "Perfect Warm" duvet, even in an environment of minus 14℃, it can maintain a surface temperature of 29.8℃, which is a warm and comfortable sleeping temperature for humans, keeping the inside of the duvet at an ideal temperature. *Thermal insulation test using thermography was conducted in an artificial climate chamber at the lowest temperature of -14℃ by an external testing organization. 2. Ultimate comfort, enveloped in warmth The skin-contact side uses a soft and smooth cashmere-touch blanket fabric. There's no worry of the blanket slipping, and you can feel the warmth as soon as you get into bed. Moreover, the fabric itself absorbs moisture and converts it into heat, providing warmth, so no extra blanket is needed. Warm yet breathable, ensuring a comfortable sleep. The entire duvet absorbs moisture, creating a bed environment that is not stuffy. Not only is it warm, but it also effectively releases moisture. 3. Ultimately clean and compact Machine washable at home. Since it's machine washable, there's no need to worry about dirt or dust mites inside the duvet. Furthermore, the Everclean layer consistently maintains cleanliness. It suppresses the growth of bacteria inside the duvet with a stronger antimicrobial property than ordinary antibacterial treatments, and also deodorizes unpleasant sweat odors. Additionally, it features an antiviral treatment to further enhance cleanliness. Only 2% of the lint generated by down duvets. By minimizing the lint generated from the duvet, there's no need to worry about house dust. Compact storage, taking up little space during the off-season. Storage is an important factor for bedding.
