Travel pillows are specially designed cushions that provide support and comfort while sitting, especially during long journeys. They come in various shapes, such as U-shaped or rectangular, and are often made from materials like memory foam or inflatable options. These pillows help reduce neck strain and improve sleep quality on planes, trains, or in cars. Many travel pillows are portable and lightweight, making them easy to carry in a bag. Some feature removable covers for easy cleaning, while others may include additional features like built-in hoods or pockets for storing small items. Popular brands include Trtl and Cabeau.
