Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter referred to as "Brain Sleep") will release the "Brain Sleep Comforter Perfect Warm EX", an evolution of the winter comforter that was launched in 2022 and recorded over 100 million yen in support purchases in the bedding category on Makuake, a support purchase service for new products and experiences. "Perfect Warm EX" uses a 9-layer thermos structure with improved heat retention and a new material that achieves moisture absorption and heat generation, making it the ultimate comforter that provides warmth, comfort without stuffiness, and cleanliness that does not generate dust mites, making it suitable for those who have winter-specific sleep issues such as cold air getting in through gaps during sleep and waking up in the middle of the night due to the comforter shifting. Reservations for "Perfect Warm EX" will begin on Makuake from 10:00 a.m. on Saturday, September 23, 2023. Development Background Currently, down is often used as a material for duvets due to its lightness and warmth, but it has many disadvantages such as washability, stuffiness, animal odor, fluffiness, and storage, so there has been a demand for the development of new materials other than down. One of the characteristics of sleep problems in winter is that cold air can get in through the gaps in the duvet while sleeping, causing the duvet to shift and waking up in the middle of the night due to the cold. In addition, stuffiness can occur even in winter, which can interfere with sleep and create an environment where dust mites and allergens are more likely to occur due to humidity. "Perfect Warm EX" was developed with the aim of creating a material and structure that eliminates all of the disadvantages of down while still providing warmth that exceeds that of down. The 9-layer thermos structure improves heat retention and the uniquely developed material "Kapok Heat EX" has high moisture absorption and heat generation power, realizing the ideal temperature of 33±1℃ and humidity of 50±5% in the bed, and the ergonomic quilt design prevents cold air from entering and enhances the heat retention effect. In addition, it is fully washable, even the inside of the futon, so it can be maintained cleanly. Features of Brain Sleep Comforter Perfect Warm EX (1) PERFECT WARM Ultimate warmth far surpassing that of feathers We have developed our own moisture-absorbing and heat-generating padding, "Kapok Heat EX." A more sustainable heat-generating technology than down, "Kapok Heat EX" is made from kapok, a plant fiber that absorbs moisture and generates heat, acrylic with high heat retention, and acrylate with high moisture absorption and heat generation properties. It is a sustainable material, yet is the ultimate heat-generating technology that converts absorbed moisture into warm heat. In the moisture absorption heat generation test, the temperature rose by 5.1°C after 7 minutes of measurement. Heat retention far surpasses that of down comforters Compared to goose down duvets, which are considered to be of high quality, it provides approximately 120% more heat retention. (2) PERFECT COMFORT The ultimate sleeping comfort, wrapped in comfort This blanket fabric has a special fiber structure that is as close as possible to cashmere, and has a soft and smooth texture like cashmere. Cashmere and wool have a special fiber structure that resembles scales, which allows them to absorb and release moisture. By developing a similar fiber structure from scratch, we have created a blanket that is highly absorbent and releases moisture, allowing you to stay in a non-humid environment. Furthermore, the moisture is effectively converted into heat, providing the ultimate in warmth. In addition, the quilt design is ergonomically designed to take into account the average shoulder width of the human body and emphasizes drape, preventing cold air from entering and improving heat retention. (3) PERFECT CLEAN Always clean and compact for storage The ever-clean layer keeps it clean at all times It has stronger antibacterial properties than antibacterial agents, suppresses the growth of bacteria inside the futon, and eliminates the unpleasant odor of sweat. Its antiviral properties maintain the ultimate cleanliness. In addition, it can be washed completely at a laundromat or at home, so there is no need to worry about dirt or dust mites inside the futon.
