Memory foam is a visco-elastic polymer that becomes softer as its temperature increases. This allows it to change its properties with the heat from the human body and quickly mould to its shape. It was originally designed by NASA to help Astronauts cope with the very high g-forces experienced as the Space Shuttle accelerated to escape velocity.
Surprisingly, Memory Foam was never used for space missions. Instead, memory foam was used to make supporting mattresses for paralysed patients having to spend prolonged periods lying in one position. They found that memory foam helped spread the pressure and stresses to reduce or eliminate the bed sores caused by lying on a standard mattress where pressure points would develop; leading to localised circulation problems and "Pressure Sores".
The manufacturing costs for memory foam have reduced over recent years; making memory foam mattresses, pillows and mattress toppers affordable for the home market.
