Pillow Positioning

The indented neck pillow supports proper cervical alignment. The thin base pillow is primarily used for superior airflow. Pillow selection and arrangement are described as important for sleep quality. The optimized pillow configuration enhanced brain drainage during sleep compared with baseline. The article identifies a two-pillow configuration as optimal after testing different pillow types and heights. The most effective setup combined a very thin pillow at the base of the neck with a pillow that had a neck indentation. Different pillow heights and configurations were tested to find a setup that optimized fluid drainage.
