A Bit About Memory Foam

Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as “viscoelastic” polyurethane foam. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover more quickly to their original shape. 


Originally developed by NASA during the Apollo program to support astronauts during lift-off and re-entry, memory foam is now mostly used in mattresses and has undergone many changes since it’s inception in the 1960s.

Memory Foam when used in a mattress can absorb body heat, creating a warmer nights sleep, however some people do not like this quality of memory foam and so temperature regulating materials such as cotton can be included in mattresses. 

Cool Blue Gel is a modern form of memory foam, which using a new formulation of base ingredients, provides the same comfort and support properties of memory foam, but disippiates heat much more efficiently creating a cooler sleeping surface. 

Memory foam mattresses come in two varieties, sprung mattresses and high density foam mattresses. Sprung mattresses generally have a longer lifespan due to springs superior support, a HD foam mattress may become softer over time as the foam is not under tension and will eventually lose its firmness. 

Memory foam isn’t for everyone and when buying any mattress it is recommended that you try before you buy so you know the level of support and comfort is going to be right for you.
