Travel pillows are an essential item for anyone who spends a lot of time traveling. They come in a variety of shapes, sizes, and materials, and can be a lifesaver on long flights or road trips.One of the most popular types of travel pillows is the memory foam pillow. These pillows are made of viscoelastic foam, which molds to the shape of your head and neck, providing excellent support and comfort. Memory foam pillows are also great for reducing the impact of turbulence or sudden movements during travel.
