Memory Foam

Memory foam is a type of polyurethane foam that has viscoelastic properties, making it soft and absorbent. It was first developed by NASA in the 1960s to help improve the safety of aircraft cushions. Memory foam is most commonly associated with mattresses, mattress toppers, and pillows, but it can also be used in items such as shoes and blankets. The foam gets its name from its ability to conform to the shape of an object and retain that shape for a period of time after the object is removed, creating a “memory” of the shape. This allows the material to provide personalized comfort and support, as it molds to the body’s shape, evenly distributing body weight and relieving pressure on joints. Memory foam is also temperature-sensitive, meaning it becomes softer when it comes into contact with body heat and hardens in cooler environments, enhancing its molding capabilities. This feature contributes to the material’s popularity in bedding products, as it can help to maintain a comfortable body temperature throughout the night.
