【Unique Ergonomic Design】The DreamLullaby sleep pillow is specially developed based on a large amount of human body data to protect the cervical spine and shoulders. The cervical spine support area has a 39-degree slope, fitting the natural curve of the neck. The recessed design of the back-sleeping area secures the head. The side-sleeping support area has a height of 11-12cm, matching half the height of the shoulder, reducing shoulder stiffness when sleeping on your side. 【Fall Asleep Quickly and Sleep Deeply All Night】You can sleep comfortably regardless of your usual sleeping position. The concave design of the occipital support area secures the head, prevents head shaking, and reduces the burden on the head. The neck support area perfectly fits the natural curve of the cervical spine, allowing the cervical spine to be in a natural and comfortable state, breathing smoothly, and falling asleep quickly. The high design of the side-sleeping support area effectively reduces shoulder stress, allowing you to experience deep sleep without stress. 【Memory Foam for Comfort】We pursue comfort and achieve the ideal firmness, adopting the optimal memory foam to relax the shoulders and neck. It slowly sinks along the shape of the head, gently wrapping and adhering closely. It supports the natural curve of the neck without putting any burden on the neck and shoulders, no matter how you sleep. While supporting the head, neck, and shoulders, it feels soft and can be adjusted to fit your sleeping position. 【Removable and Washable Class A Mother and Child Grade Pillowcase】The pure cotton pillowcase uses mother and child grade fabric, which is gentle on the skin and suitable for temperature, allowing you to experience comfortable sleep all night. The cotton pillowcase contains 95% cotton and 5% spandex, is soft and breathable, and can absorb moisture and retain moisture. The pillowcase is washable. 【Quality Assurance, Customer First】DreamLullaby provides not only a high-quality cervical spine pillow but also reliable after-sales service. This cervical spine pillow is made of high-quality memory foam certified by the authoritative SGS institution. It uses high-density, low-rebound, and harmful substance-free memory foam. It is safe and harmless, so you can use it with confidence.
