ABCs of Memory Foam

Regardless of the manufacturer, there are several key things – the ABCs if you will – that are universal among Memory Foam mattresses. Knowing the ABCs of Memory Foam will help maximize the consumer’s experience.
Memory Foam is the product of NASA research into ways to protect astronauts from harmful G-Forces. All Memory Foam, regardless of the manufacturer, is derived from this research and utilizes polyurethane based foam.
Memory Foam gets its body-contouring properties from the heat sensitive nature of visco-elastic foams. Memory Foam mattresses are able to evenly distribute weight – and therefore eliminate uncomfortable pressure points – because the foam softens as body heat is applied. When the heat source is removed, Memory Foam will rebound to its original shape within minutes.
Mattress density varies. Lower density products are less expensive to manufacture but will be the quickest to break down. The bottom layer is called the core. On top of this is a more viscous layer which can vary in thickness usually between two to six inches. Variations in density will determine softness and price point of the bed.
With Memory Foam, cheaper is not better. Typically, the denser the Memory Foam is, the higher the cost to the consumer. But the comfort level also increases with the rate of density, making the money well spent.
High quality Memory Foam is generally very durable particularly if compared with many inner spring mattresses and does a better job of resisting bacteria, mold and pests such as dust mites and bed bugs. Memory Foam is still a relatively new product, but these mattresses are generally considered equal in longevity to comparatively priced conventional mattresses.
