Ergonomic design: The pillow uses a butterfly shape that conforms to the natural curve of the neck, providing precise support for the neck and shoulders. It helps keep the spine aligned and reduces pressure on the cervical spine and neck fatigue. Memory foam core: The pillow core is quality memory foam with slow rebound characteristics. It automatically shapes to the user's body temperature and the head and neck contour, delivering comfort and maintaining stable, effective support. Relieve neck fatigue: It delivers targeted neck support and distributes pressure to relieve fatigue from long periods in the same position or poor sleeping posture, promoting relaxation and recovery of neck muscles and improving sleep quality. Breathability and cover: The memory foam and cotton pillowcase offer breathable performance, releasing moisture and heat to keep the pillow dry and comfortable. This helps prevent sleep quality decline due to stuffiness and can extend the pillow's service life. Materials and design features: Core material is memory foam; outer cover is a cotton pillowcase. Butterfly ergonomic design is focused on supporting the neck and shoulders with breathable construction. Practical use scenarios: 1) Use for regular night sleep to improve spine alignment and neck comfort. 2) Use after long periods of desk work or screen time to relieve neck fatigue and promote muscle relaxation. 3) Use in warm or humid environments to maintain a dry, comfortable sleeping surface and sustain sleep quality.
