This is a Teijin futon mattress. I purchased it on Amazon for 5555 yen and used it a few times, but I am selling it because I am upgrading the size of my bed. I am also selling futon covers and other bedding items, so if you are interested in purchasing multiple items, I will do my best to offer a significant discount, so please feel free to contact me. #Beddingkkk ① Product size: Approximately 100cm wide x 210cm deep x 10cm high (includes 5cm urethane foam) ② Product weight: Approximately 4.5kg ③ Material/Outer fabric: 100% polyester (peach skin finish) ④ Filling: 100% hollow polyester (using TEIJIN Mighty Top filling) 【Comfortable feel and five-layer futon mattress】 The surface layers on both sides are filled with fluffy filling, providing excellent sleeping comfort. The non-woven fabric separates the filling and urethane, making it easier to maintain the shape of the filling, preventing it from collapsing, and increasing durability. The approximately 5cm of urethane effectively supports the body, preventing the futon mattress from collapsing. The inclusion of urethane provides balanced support for the entire body, maintaining an S-shaped sleeping posture, and allowing for comfortable sleep. 【Thick 10cm volume for a firm sleeping experience!】 The core material of the futon mattress, which affects sleeping comfort, is tuned with high-resilience urethane with excellent pressure distribution. It provides a soft and fluffy sleeping experience while also providing firm support, making it easy to turn over. It supports the body without sinking in too much, providing a balance of support and sleeping comfort. 【Microfiber filling】 The filling uses fluffy, ultra-fine polyester fibers, making it softer, lighter, and fluffier compared to conventional filling products. The filling uses Teijin's "Mighty Top," which has anti-mite, antibacterial, and deodorizing effects. The antibacterial and deodorizing effects of "Mighty Top" suppress the odor of sweat and the growth of bacteria, maintaining cleanliness. Please enjoy the fluffy feel unique to a freshly made futon mattress. The ultra-thick volume of approximately 8-10cm allows for a comfortable sleep. With its fluffy feel and no feeling of the floor, it provides an exquisite sleeping experience and supports high-quality sleep. 【Antibacterial and deodorizing - SEK mark certified】 With the SEK-certified excellent antibacterial and deodorizing effects, it suppresses the growth of bacteria and exhibits deodorizing effects. Produced in an "ISO9001" certified factory, it is low in formaldehyde and of safe quality. #Beddingkkk
