This height-adjustable inflatable travel pillow lets you customize its firmness as needed with an included pump. It features a built-in high-pressure airbag inner core that can be manually inflated using the provided inflator ball. The pillowcase has a convenient zipper design for easy removal and washing, just remember to take out the inflation tube first before removing the cover. Compact and lightweight at just 250g, this inflatable cushion folds up easily when not inflated, making it small and easy to carry for business trips or travel. The cloth cushion cover is made from soft, durable polyester fabric that stays comfortable with regular use and resists snags and fraying over time.
