【Ergonomic Design】This pillow is designed based on ergonomics. It fills the gap between the neck and the pillow, providing support and fitting the curve of the neck. The arched shape fits the curves of the shoulders and neck, guiding your head into a natural curve just by resting on it, relieving pressure on the neck and shoulders. 【Comfortable in Any Sleeping Position】When sleeping on your back, it keeps your neck and cervical spine in a natural shape, making sleep easier and reducing the number of times you turn over, allowing you to sleep soundly. When sleeping on your side, the height of your shoulder width perfectly matches the height of both sides of the pillow, providing firm support for your neck and relieving pressure on your shoulders. 【Relaxing High-Density Memory Foam】It uses "memory foam," which has higher shock absorption than general urethane. It reacts to body temperature and pressure, slowly sinking in to conform to the shape of your head, enveloping it and providing comfortable sleep without burdening the neck and shoulders. 【Skin-Friendly, Washable Cover】The original cover has a gentle feel, excellent breathability, absorbs and wicks away sweat during sleep, and maintains a comfortable sleeping environment. Of course, it is also antibacterial, deodorizing, and mold-resistant. It has a zipper, is removable, and is washable, so you can always keep it clean. 【Perfect for Gifts】Recommended as a birthday or Christmas present. Other occasions include weddings, childbirth, housewarming,入学/ご就職/ご新築/リフォーム/お中元/お歳暮/Father's Day/Mother's Day/敬老の日, and other celebrations and gifts. B5-299 $$2280
