Brain Sleep Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") has obtained a patent for its uniquely developed "Float" mattress structure, based on ergonomics and sleep science. This structure divides the mattress into head (shoulder), waist, and leg sections, optimizing pressure distribution by designing the optimal firmness for each body part. Additionally, the raised leg section recreates the zero-gravity posture, said to be the most relaxing position for humans. Furthermore, it has been found that this posture improves blood flow.Brain Sleep will continue to contribute to creating a comfortable sleep environment through innovative technological development, delivering healthier lives to more people. Development Background Brain Sleep focused on research indicating that the natural posture adopted by humans in a zero-gravity environment is the ideal posture for maximum mental and physical relaxation. Aiming to replicate this posture on a mattress during sleep, we embarked on unique technological development. This delivers an unprecedented new sleep experience, something not achievable with conventional uniform structures. Features The development of this structure has demonstrated the following data:Improved blood flow: Significantly increased blood flow compared to conventional products.Relaxation effect: Increased alpha wave content in EEG measurements, decreased LF/HF ratio in ECG.Pressure distribution effect: Reduced pressure on the lower back from 8.0kPa or more to less than 6.0-7.0kPa.Optimized sinking depth: Achieves ideal sinking that reduces the burden on the body. Patent Overview Patent number: No. 7727279Registration date: August 13, 2025Name of invention: MattressApplicants: Brain Sleep Co., Ltd., Eco-World Co., Ltd., Teijin Axcis Co., Ltd. (formerly Texel Co., Ltd.) "Brain Sleep Mattress Float" Series The "Brain Sleep Mattress Float" series combines ideal sleeping posture with ultra-pressure distribution. ＜Common Features＞ 1. Zero-gravity technology creates the ultimate relaxing posture Recreating the neutral posture advocated by NASA When the body is left to its own devices in space, the shoulders naturally pull inwards and the legs rise. This is considered the least burdensome posture for the body. This posture is replicated with a unique structure featuring a complex woven layer of polyethylene fibers combined with a "float" design where the foot section is elevated. This creates a floating-like repulsion and optimal firmness tailored to the legs, waist, and shoulders, promoting the ultimate relaxed posture, free from gravity. 2. Optimal sleeping posture maintained with ＜zoning support＞ tailored to body parts "Wire waves," wire-like support cores with fiber thickness adjusted according to body parts, support the body from inside the mattress. They support different body pressure points, preventing excessive sinking and maintaining an ideal sleeping posture. 2. Excellent breathability for comfortable sleep without heat retention Ultra-breathable material controls temperature and humidity for optimal sleep To achieve good quality sleep, it is important to maintain appropriate temperature and humidity within the bed.Composed of over 90% air layers, it prevents heat and humidity from building up during sleep, creating a comfortable sleeping environment. 3. Long-term durability & clean and stain-resistant 【Excellent durability】 Can be used for 10 years Durability is a concern for mattresses used daily.This product has demonstrated high durability even after 80,000 compressions, meeting JIS standards. A stable sleeping experience continues even with long-term use.*Durability may vary depending on usage. 【Can be washed with a shower and kept clean】 Dust mites and house dust are less likely to occur The cover can be removed and machine-washed, and all the core material of the mattress can also be washed.The core material can be rinsed clean with a shower and easily dried by simply air-drying in the shade after showering.Brain Sleep mattresses are highly breathable, making them less prone to dust mites and mold, and can be washed anytime if house dust or dirt becomes a concern, thus maintaining a clean condition.
