Flexible foam is a type of material made from polymers that can easily bend and compress. It is commonly used in products like mattresses, cushions, and upholstery because it provides comfort and support. The foam can return to its original shape after being compressed, making it ideal for various applications. This material is often produced through a process called polymerization, where chemicals react to create a lightweight and durable foam structure. Flexible foam is also used in packaging, automotive interiors, and soundproofing, showcasing its versatility across different industries.
