Seat cushions are padded accessories designed to enhance comfort while sitting. They can be used on various surfaces, including chairs, benches, and car seats. Made from materials like foam, gel, or memory foam, seat cushions help reduce pressure on the body and improve posture, making them popular for long periods of sitting. These cushions come in various shapes and sizes, catering to different needs. Some are specifically designed for ergonomic support, while others focus on portability and ease of use. Many people use seat cushions at home, in the office, or during travel to promote better comfort and reduce discomfort associated with prolonged sitting.
