The top layer uses low-resilience material to gently cradle your head and neck, distributing pressure and promoting relaxation. The middle layer features a special cylindrical support that accurately supports the natural curve of your neck, reducing fatigue caused by neck strain during the night. The bottom layer's excellent pressure resistance provides stable support for your head and neck, providing a sense of security. This low-resilience pillow uses high-density memory foam material. It achieves a supple feel while enabling more precise pressure distribution. The internal cylindrical support layer fits perfectly to the curve of the neck, effectively reducing strain. It provides a soft, delicate enveloping feel and comfortable resilience throughout the night, creating a "custom-made neck and shoulder fit pillow" that keeps the neck in a natural state, adapting to individual body types and sleeping positions. It maintains the ideal neck position in any posture, whether sleeping on your back, side, or stomach, leading to a deep sleep that relieves the day's fatigue. This deep sleep pillow has a built-in highly breathable inner cover (a delicate structure that wraps the filling), significantly improving breathability while maintaining a soft texture. It feels like the pillow is breathing, providing lasting coolness. The special striped groove design on the surface forms air passages, greatly increasing breathability. It efficiently releases heat and moisture that tends to accumulate in the head during sleep, keeping you comfortable, cool, and dry. The double ventilation structure of the neck-pain-free pillow allows you to spend the hot season comfortably all year round, and the non-stuffy environment leads to deep, high-quality sleep. This low-resilience pillow uses a reversible pillowcase that can be used according to the season and your preference. The "white side" has a skin-friendly texture and excellent elasticity, fitting the pillow snugly. It is characterized by its resistance to slipping and wrinkling even during sleep. The "blue side" is made of the same material but with an adjusted mixing ratio, achieving a smoother and cooler feel. Use the cool blue side in summer and the skin-friendly white side in other seasons, or switch between them according to the season and your mood.
