Memory foam, also known as viscoelastic foam, is a material that molds to the shape of whatever presses against it, distributing weight evenly. It was originally developed by NASA in the 1960s to improve the safety and comfort of aircraft cushions. This unique property allows memory foam to reduce pressure points, which is why it's widely used in mattresses, pillows, and other comfort products.

The primary component of memory foam is polyurethane, to which additional chemicals are added to increase its viscosity and density. When pressure is applied, the foam's structure temporarily deforms. Upon removal of the pressure, it slowly returns to its original shape, hence the name "memory." The rate at which it returns to its original form can vary depending on the foam's formulation.

Memory foam's ability to contour to the body makes it a popular choice for individuals experiencing joint pain or seeking enhanced comfort and support. It can help align the spine and reduce the need for tossing and turning during sleep. However, some users find that traditional memory foam can retain heat, leading to a warmer sleeping experience. Manufacturers have developed various cooling technologies, such as gel-infused foam or open-cell structures, to mitigate this. Memory foam is also used in medical applications, like wheelchair cushions, to prevent pressure sores.
