U-Shape Design:
The most common shape, designed to wrap around the neck and provide support, especially when you're sitting upright (e.g. on a plane or bus).
Soft and Comfortable Materials:
Usually made from memory foam, microbeads, or soft cotton/polyester fillings that adapt to your neck shape and provide comfort.
Removable and Washable Cover:
Most travel pillows come with a removable outer cover that can be easily washed to maintain hygiene.
