Air-filled cushions are soft, flexible pads that contain air, providing comfort and support. They are commonly used in furniture, such as sofas and chairs, to enhance seating comfort. The air inside the cushions allows them to adapt to the shape of the body, distributing weight evenly and reducing pressure points. These cushions can also be found in various applications, including bicycle seats, car seats, and medical devices. They are often made from durable materials like vinyl or nylon, ensuring they can withstand regular use while maintaining their shape and functionality.
