So what makes memory foam have a memory? It's all about weight and density. The process of making this foam is the most important aspect of it all. By adding certain chemicals you can really make this product have "memory."
During the manufacturing process you start with basic, synthetic polyurethane foam. Then this material has chemicals added to it that dramatically increase the weight and thickness of the foam. Have you ever felt how heavy this product is? It's heavy!
When these chemicals are added to the manufacturing process of the synthetic polyurethane foam a new material is created. It is now a visco-elastic foam material that is safe and non-toxic.
So once the memory foam has been given its "memory" it is now ready to be shipped to your local mattress store or to the warehouse waiting to be ordered.
How Does This Product Work?
Well the "memory" in memory foam refers to the fact that when you lay down it conforms to your body but when you get up the parts of the foam that had conformed to your body "remember" what the original form was and return to it.
So it becomes flat again. This is a result of the visco-elasticity which is a result of the pressure, weight, and body heat you give off.When you lay on the bed the "memory cells" within the mattress warm up and get soft thus you sink down into the mattress. It conforms to your entire body shape giving you unparalleled support and comfort.
