nishikawa Pillow special 3D structure that deepens your sleep High Blue High fit with uneven shape and neck support system Head pressure dispersion

Size: 61X34X13cm Composition: Side fabric: 100% polyester Filling: Urethane foam Country of origin: Japan [Air 3D] series pillow. The renewed type has significantly improved the shape and weight of the upper part. Unique design based on [Neck Support System]. It has a "center concave" structure that firmly stabilizes the head and fits snugly against the nape of the neck. The high cushioning properties allow for smooth tossing and turning while alleviating the burden on the cervical vertebrae. In addition, the ``higher sides'' structure maintains the height even when sleeping on your side. *Neck support system: In order to support the head and cervical vertebrae in a natural posture, we researched and developed a pillow that provides the best position. In search of comfort value, we propose a system for selecting the correct pillow that suits each individual. The 3D structure fits the neck and back of the head. The second layer has a built-in filmless urethane material that improves breathability and allows moisture to escape every time you turn over. Breathability is ensured using urethane foam with uneven shapes of different sizes.
