BrainSleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "BrainSleep") is pleased to announce that its signature product, the "BrainSleep Pillow" which helps the brain sleep, and the "BrainSleep Mattress Float" which controls sleeping posture and core body temperature, have been adopted for the "Relax Lounge Building" in the outdoor bathing area of the Osaka-Kansai Expo Sauna . Furthermore, the "BrainSleep Mattress Float" will be specially designed for this outdoor bathing area. The sauna is built with a structure that uses tetrahedron-shaped units, composed only of minimal aluminum frames, ETFE film, and air, which are adopted for the first time by Taiyo Kogyo Corporation, a global leading company in membrane structure architecture. It will be available for experience during the exhibition period from April 13 (Sunday) to October 13 (Monday, national holiday). Background of the initiative The "BrainSleep Pillow" and "BrainSleep Mattress Float" introduced this time offer excellent breathability, efficiently dissipating body heat that rises after a sauna bath and promoting relaxation. Furthermore, these products incorporate a circular design*1 where material scraps generated during manufacturing and products collected due to size exchanges are re-materialized at the manufacturing plant and regenerated as new products. By utilizing 100% recyclable materials, they contribute to waste reduction. Such initiatives align with the philosophy of realizing a sustainable future under the theme "Designing Future Society for Our Lives." For these reasons, they have been officially adopted for the "Relax Lounge Building" in the outdoor bathing area of the sauna within the Expo. Relationship between Sauna and SleepIn July 2022, BrainSleep conducted a verification of "the effect of sauna bathing on sleep." The results showed a tendency for an improvement in the duration of deep sleep (stage 3) and delta power, an indicator of deep sleep, during the first 90 minutes of sleep (sleep cycle 1), which plays the most crucial role in sleep quality, when sauna bathing was incorporated*2.Dissipating the core body temperature elevated by sauna bathing is an important process for "totonou" (achieving a state of deep relaxation) during outdoor bathing. Outdoor bathing helps balance the autonomic nervous system, leading to profound relaxation. By installing the highly breathable "BrainSleep Pillow" and "BrainSleep Mattress Float" in the relax lounge building, it is expected to efficiently dissipate body heat elevated by sauna bathing and enhance post-sauna relaxation. *1 Action taken against the low recycling rate of bedding that "changes the future with sleep" by introducing proprietary technology!

Expo Sauna General Producer, Sauna Master Daisuke Akiyama's Comment For the sauna experience at Expo Sauna , we placed the highest importance on "resting," which is often referred to as the main dish of "totonou" (achieving a state of deep relaxation), even more than the experiences in the "sauna" and "cold bath." While considering how best to allow for "rest" amidst the 3D sound and lighting programs, I arrived at the idea of lying horizontally with the feet slightly elevated. In realizing this idea, BrainSleep proved to be perfect in terms of design, functionality, and experiential value. The special custom version created for Expo Sauna has been very well received by visitors after their experience as a new approach to outdoor bathing, and I believe it will become a new standard in the sauna industry going forward. Please come to the Expo Sauna and experience a new sensation of "totonou" with a floating feeling.

Focusing on improving sleep quality, it combines excellent breathability with a comfortable fit achieved by its patented 3-layer, 9-gradation structure. 1. Excellent breathability for "cooling the brain, sleeping faster and deeper" Composed of over 90% air, it prevents heat and humidity from accumulating in the pillow during sleep, creating a comfortable sleeping environment. 2. 3-layer, 9-gradation structure achieving a personalized fit with unique patented technology It features an "adjust layer" that softly conforms to the shape of the head, a "support layer" that firmly supports the head and neck, and a "base layer" that allows air to escape from below. These layers vary in fiber thickness and density, creating a rational structure. The 3-layer, 9-gradation structure, which gradually fits the size of the head and sleeping position, is realized with patented technology. It becomes a personalized pillow with each use. 3. Cleanable by showering with water It is said that humans sweat about one cup (approximately 200ml) while sleeping. Since over 90% of the pillow is made of an air layer, its excellent breathability prevents moisture accumulation, making it hygienic. Furthermore, not only the cover but also the core material can be washed with water, and it dries quickly, so it can always be kept clean. ＜Product Details＞ Product Name: BrainSleep PillowPrice (tax included): 33,000 yen (tax included)Product URL: https://brain-sleep.com/products/pillow Mattress that controls sleeping posture and core body temperature"BrainSleep Mattress Float" The BrainSleep Mattress series recreates the "neutral posture" advocated by NASA, which places less burden on the body. A distinctive feature is that the leg section is designed to be 4cm higher than the chest, which facilitates blood circulation to the chest, reducing fatigue and swelling. Furthermore, it supports turning over with ultra pressure distribution that repeatedly absorbs and rebounds with every movement. Like the pillow series, it is made of over 90% air layer, providing high breathability and can be washed with water to maintain hygiene, creating a comfortable sleeping environment. ＜Product Details＞ Product Name: BrainSleep Mattress Float Price (tax included): From 88,000 yen Sizes: Single to Queen Product URL: https://brain-sleep.com/products/mattress_float
