The Composition and Benefits of Memory Foam

Memory foam, originally designed for NASA in the 1960s, is made from viscoelastic material. It consists of polyurethane layers and components like polyols, diisocyanates, and blowing agents. Memory foam adapts to body heat and pressure, providing support and comfort. It is denser than regular foam, making it more durable. Its applications extend beyond mattresses to helmets, shoes, and medical seating pads.
