The wave-shaped side fits the curve of the neck and head, supporting the neck firmly, preventing shoulder and neck pain. The concave side is designed with a concave center and higher sides, so when sleeping on your back, use the center, and when sleeping on your side, the higher sides naturally lift your head, keeping your cervical spine in an ideal state and maintaining a comfortable sleeping posture. [Easy Breathing, Sound Sleep Until Morning] When the airway is narrowed during sleep, it can be difficult to breathe, which can interfere with deep sleep. This comfortable sleep pillow has a height adjustment function that can be adjusted to your body and a shape that naturally lifts the chin, which opens the airway and makes breathing easier, allowing you to sleep in a more relaxed state. Provides comfortable sleep for yourself and your family! [Achieves the Ultimate Sleeping Comfort] The low-rebound pillow uses high-quality low-rebound memory foam from BASF, Germany, characterized by its elasticity that doesn't sink in too much and excellent stability. It slowly envelops the shape of your head, evenly distributing pressure on your head, neck, and shoulders during sleep, while firmly supporting your head, neck, and shoulders. The large size of 63x40cm prevents your head from slipping off the pillow when you turn over, and it has plenty of room for people with larger builds. The washable, cooling-touch cover prevents heat build-up and keeps your head cool, supporting smooth sleep onset.
