The sides are slightly higher by about 2cm, making it more suitable for side sleeping and when you turn over while sleeping with your neck raised by your shoulders, providing a more intimate and comfortable fit. The middle under the arc is slightly recessed, allowing it to fully absorb the curve of the back of your head and provide the most correct support for your head and neck. ✨ Breathable ✨ The pillow core, made of memory foam, has a fine open-cell structure. It moves with your body during sleep, breathing with you and promoting airflow within the pillow, improving the comfort of your sleep environment. ✨ Self-shaping ability ✨ The special material of the memory foam pillow sinks under external pressure. However, due to the temperature-sensitive particles it contains, it has viscoelasticity and temperature sensitivity. It remembers the shape created by the object it contacts and only regains its original shape after the temperature gradually returns to normal. This memory deformation and self-shaping ability can fix your head and reduce the possibility of it falling off the pillow. Its self-shaping ability can properly fill the gap in your shoulders, effectively preventing cervical spine problems and avoiding the common issue of air leakage from the shoulder area. ✨ Shock Absorption ✨ The memory foam contains temperature-sensitive memory particles that change shape according to body temperature and pressure, effectively relieving body pressure and counteracting reaction force, providing the most uniform and true support. It keeps the contact areas of your body relaxed for a long time. By supporting your head and neck evenly, the pillow gives you a feeling of floating on water or clouds, and your skin feels no pressure. While using a regular pillow may cause pressure on your ears, this does not happen with a memory foam pillow. Antibacterial and Anti-mite - The memory foam sponge inhibits mold growth and repels the irritating odor caused by mold growth when there is sweat or saliva. $$2800 Takkyubin (Home Delivery Service) Pillow, Makura, Peaceful Sleep Pillow, Low Rebound Pillow, Comfortable Sleep Pillow, Turning Over/Breathing Dispersion, Body Pressure Dispersion, Polyurethane, Wavy Line Support, Air Pillow, With Pillowcase, Washable (W500*D300*H100mm)
