memory foam was invented by NASA in 1966 .
A term that is not commonly used in everyday conversation is ‘viscoelastic’. Viscoelastic foam is another way of saying memory foam. The method of manufacturing viscoelastic foam varies depending on the formula used by the company. These different formulas change the qualities of the foam. For instance, some types of viscoelastic foam might be more resilient to changes in the shape of a body that is lying on them. It might take longer to mold to the exact shape of the person. Visco foam is solid and dense. This means that most substances cannot pass through the surface. However, the foam also displays elastic properties. It is able to recover its shape over a certain period of time. It will soften when you lie on it but will return to its original shape when you get up.
Types of memory foam.
Traditional memory foam,Opencell structure memory foam,Gel inserted memory foam, gel particles memory foam and responsive memory foam.
Tranditional memory foam provides for a good sleep experience by molding to your body. One of the biggest complaints, which we’ll go over in a later section, is the fact it has a tendency to retain body heat, making it uncomfortable to sleep in high temperatures.
Open cell memory foam is your basic memory foam with a different internal structure. Open cell memory foam allows for a better movement of air inside the mattress, allowing it to better transfer heat away from your body as you’re sleeping.
Gel memory foam, or gel-infused memory foam, is memory foam that has been pumped full of gel, which also has two different types. The first is a kind of material that just absorbs heat. Think of this like an ice pack you might keep in your freezer. The other type is actually what is called a phase-changing material. What this stuff does is help regulate your temperature as you sleep by absorbing and releasing heat.
