The ergonomic hollow contour pillow is designed to alleviate neck pain and discomfort by combining the benefits of a traditional bed pillow and a contour pillow. Its hollow concave surface, tilted at a 15° angle, cradles the head while maintaining the natural curve of the neck and aligning the spine. The pillow features six unique contour zones that provide full support to the neck, shoulders, and arms, addressing targeted pressure points to alleviate neck pain and muscle stiffness. Made of 98% breathable memory foam, the pillow is non-toxic, odorless, and enhances airflow for a cool and comfortable sleep. The pillowcase utilizes a highly dense 3D mesh design for excellent breathability and includes a Q-Max 0.4 Arc-Chill cooling pillowcase that reduces skin temperature by 5℃. The pillow is customizable with the ability to rotate it 180° or remove the bottom insert to find the perfect sleep height, promoting a 15° golden ratio of ARC neck traction for enhanced deep sleep. The pillow is suitable for those seeking to improve their sleep quality and restore the body's natural curves. Color: Grey.
