MUJI Popular Pillow That Accommodates Tossing and Turning Used for just under six months with a pillowcase. While there are no noticeable scratches or stains, please check the photos for the condition as it is a used item. The structure and design of this pillow smoothly accommodates any sleeping position, whether you sleep on your back or side, which changes with tossing and turning. The center part is lower and softer than the sides, designed to allow your neck to be at a natural angle when sleeping on your back. When sleeping on your side, it is desirable for your neck and spine to be straight, and for your shoulders not to be compressed, so the sides have been made higher and firmer. *The "appropriate height" may not be suitable for everyone, depending on your physique and the mattress you use. 【About Materials】 It is highly breathable, does not get stuffy, and can be washed with a shower, making it hygienic. 100% recycled polyethylene is used. Scraps generated during the manufacturing process are reused within the factory. 【Care Instructions】 ① If you are concerned about sagging Set the water heater temperature to 42°C to 50°C and apply hot water with a shower to the areas you are concerned about sagging. *Please refrain from using hot water of 51°C or higher, as it may degrade the quality. ② If you are concerned about odors or stains and want to maintain it Rinse with a shower using room temperature water.
