Flexible foams are soft, lightweight materials commonly used in various applications, including furniture, mattresses, and automotive interiors. They are made from polymers, primarily polyurethane, which allows them to compress and return to their original shape. This property makes them ideal for providing comfort and support. These foams come in different densities and firmness levels, catering to specific needs. For instance, memory foam is a type of flexible foam that conforms to the body, offering pressure relief. Flexible foams are also used in packaging, insulation, and soundproofing due to their ability to absorb shock and reduce noise.
