A memory foam neck pillow is designed to provide support and comfort for the neck during sleep or travel. Made from viscoelastic foam, it conforms to the shape of the neck and head, helping to maintain proper alignment of the spine. This can reduce discomfort and improve sleep quality. These pillows are often used by people who experience neck pain or stiffness. They are available in various shapes and sizes, making them suitable for different sleeping positions. Many memory foam neck pillows also come with removable covers for easy cleaning and maintenance.
