Ergonomically designed, with a wave shape, it perfectly fits the curves of the head, neck and shoulders, provides scientific support and relieves cervical pressure. The high-density memory foam slowly sinks, rebounds naturally, and evenly disperses the pressure, giving people a zero-pressure feeling and helping users fall asleep quickly. The pillow surface is covered with environmentally friendly silicone gel, which provides a long-lasting cool touch, helps to effectively cool down in a hot environment, and creates a comfortable sleeping temperature.
