Thank you for taking a look at our product from among many others!! 【Online Retail Price】 5,680 yen 【Color】 White 【Size】 55x52x20cm Weight: 1.47kg 【Patented Double Structure】 This new triangular cushion employs a patented two-layer structure (Utility Model Registration No. 3244666). The upper layer uses silicone wadding and low-resilience urethane chips, while the lower layer uses high-resilience urethane with a density of 25D. This combination perfectly balances softness and support. Conventional triangular pillows were made only of urethane, providing high support but lacking in comfort. However, this newly developed triangular cushion combines flexibility and support, offering the best sleeping experience. 【Double Structure, Comfortable】 The upper layer of low-resilience urethane chips is fluffy and provides a soft, comfortable feel. The lower layer of high-resilience urethane provides firm support and is resistant to sagging. It prevents the body from sinking in, firmly supporting from the lower back to the shoulders, and supporting comfortable sleep and relaxation. 【As a Pillow】 By placing it sideways, it can be used as a pillow, allowing you to sleep comfortably in both the supine and lateral positions at the perfect angle. It is especially helpful for the elderly and pregnant women. When it's difficult to lie on your back in the later stages of pregnancy, using it as a pillow for side sleeping reduces the burden on the neck. 【As a Backrest Cushion】 This cushion can be used vertically as a lumbar support and is useful in various situations. Placing it between the bed and the sofa, or the floor and the wall, is perfect for relaxing while reading a book, watching TV, or using your smartphone. Its sturdy construction also makes it a great gift for housewarmings, etc. 【Easy Care】 The cover has a large zipper, making it easy to remove the urethane! When the cover gets dirty, remove the lower layer of urethane, put it in a net, and wash it in the washing machine. (Please note: To prolong its life, please refrain from frequent washing.) *This is an opened item, but it appears to be unused with no odors. *This item does not come with a box, so it will be packaged and shipped.
