It provides a balance of comfort and support in various sleeping positions, such as back and side sleeping, relieving tension in the shoulders and neck and reducing the number of times you toss and turn. The high-density memory foam dynamically conforms to the pressure of your head, providing a zero-pressure sleep experience. The breathable pillowcase feels soft and cool, instantly improving sleep quality. This is not just a pillow, but a scientifically designed comfortable deep sleep experience. 【Scientific Support with Ergonomic Design】The pillow adopts a 3D split design of "head zone, cervical spine support zone, and shoulder fit zone," accurately supporting each part to bring out the natural curve of the cervical spine. It maintains a comfortable line for the entire spine, providing even support in any sleeping position and promoting deep sleep. Every night, you will feel the comfort that perfectly fits your body, preventing shoulder stiffness and neck pain the next day. 【High-Density Memory Foam】The pillow core uses 60D high-density memory foam, which adjusts its shape according to the pressure of the head and neck with a slow rebound force. It reduces localized stress and flexibly adapts to all movements, such as back sleeping, side sleeping, and tossing and turning, providing a natural and smooth sleep experience. The combination of high resilience and a soft feel makes it resistant to sagging even after long-term use, maintaining stable support. 【Two-Stage Height Design】The two sides of the memory foam pillow are designed with heights of 6cm (low) and 10cm (high), allowing you to choose freely according to your preference and sleeping position. If you want firm support for your cervical spine when sleeping on your back, or if you want to fill the gap with your shoulder when sleeping on your side, we recommend the 10.5cm high side; if you prefer a low pillow, or if you sleep on your stomach, the 5.5cm low side is suitable. Anyone can find the optimal height for themselves and enjoy a personalized sleep experience. Management number 1102999
