Purchased on Rakuten Ichiba in May 2025. Used with a cover. Honeycomb structure donut-shaped baby pillow, breathable mesh material. - Color: White - Design: Honeycomb structure - Material: Mesh material - Shape: Donut-shaped - Usage: Baby pillow 【Point 1: 3D Structure】 The smooth slope fits the shape of the baby's head and disperses pressure on the head. The slope can also act as a wall, preventing the baby from rolling off the pillow. 【Point 2: Freely Adjustable Size】 The height of the pillow is adjustable, allowing you to protect the baby's head. It helps solve concerns about babies, such as flat head syndrome and head-turning preferences. 【Point 3: Absorbent and Breathable, Non-Muggy Pillow】 Babies are very delicate. If they sweat a lot and get stuffy, they can develop a rash. The pillow uses two types of materials to provide comfort throughout the year. Side A is 100% cotton, which is absorbent and has excellent texture. Side B uses mesh fabric, which is breathable and less prone to stuffiness. 【Point 4: Washable at Home】 Babies sweat a lot while sleeping, so you want to choose something that is easy to care for. Also, the inside of the pillow can get dirty from spit-up... This concern is solved because you can wash it at home. (Please use a laundry net when washing at home.) 【Point 5: Carefully Selected Safe Materials! Domestic Quality Inspection Completed】 This product is safe and secure, having undergone quality inspection by a specialized domestic organization to ensure it is safe for babies to use.
