The Benefits Of Memory Foam
-
Memory foam is a type of polyurethane foam known as "viscoelastic" polyurethane foam or low-resistance polyurethane foam (LRPu). It's a plastic that can be found in a variety of items, including sofas, mattresses, insulation, and spray foam. It got its name because of its ability to change shape under pressure, but return to its original shape when the pressure is removed. This allows it to adapt to your specific shape and provide additional head and neck support. It is made by incorporating several chemicals and additives into polyurethane, depending on the type of foam being produced. Finally, these compounds have an effect on two of the most important properties of memory foam: viscosity and elasticity. When we say memory foam is "sticky," we imply that it takes a long time to change shape or transfer energy from one location to another under pressure.
When we say a material is "elastic," we imply that it can stretch or twist, but return to its original shape or size once the stretching force is removed. Different manufacturers have different "recipes" for the chemicals they add to the foam and the techniques they use to make the foam. These formulas and techniques, often a private secret, can have an impact on how each specific memory foam product feels and functions. However, most viscoelastic foams used in memory foam mattresses contain at least some level of a substance called polyether polyol, which contributes to the elasticity and viscosity of the foam.
