This is an air-type folding cushion. The air structure disperses body pressure, making it comfortable to use even when sitting for long periods. When in use, it provides firm cushioning, and when not in use, you can deflate it for compact storage. It's lightweight and easy to carry, fitting in bags and backpacks. It's a convenient item that's useful in various situations, such as outdoors, events, airplanes and overnight buses during travel, and on top of a leisure sheet. The color is a calm khaki.
