Memory Foam is special foam originally developed to support Astronauts in the NASA Space Programme. The original use of the material was to reduce the effects of G-Forces on the astronauts involved in space flight. The material would cushion the impacts of all forces involved in flight and would give the astronauts greater protection for the body Since then, memory foam has been developed for various commercial uses, and has been endorsed by many Medical Institutions, osteopaths and physiotherapists, for it's unique pressure relieving properties which assist and improve circulation and help to reduce pressure sores.
