A scientist named Charles Yost was hired to engineer a mattress for the use by the National Aeronautics & Space Administration agency, more commonly known as NASA agency. They wanted a material that could protect against the impact of the g-forces on takeoff.  After the initial production of memory foam for this purpose Yost worked in collaboration with NASA to help commercialize the foam and it was then released to medical institutions.

What exactly is memory foam?

Memory foam is made with something called polyurethane and has added chemicals mixed in with it to help increase the elasticity and viscosity of the material. It is usually referred to as memory foam but it is actually called ‘visco-elastic foam’ or low-resilience polyurethane foam. Memory foam can come in two varieties; High density memory foam which softens to body heat and low density memory foam is more pressure sensitive and moulds to whatever the pressure is. High density foam moulds to the heat of the warm body rather than the pressure.

What does memory foam do?

Memory foam has an open cell structure and it is designed to react to body heat and weight. When pressure is applied to the mattress it moulds to the sleepers body, which can help in many ways. Pressure points are supported efficiently and comfortably by the body moulding technology.

Memory foam also has a special technology that can help to regulate your temperature, dispersing heat into the reactive mattress when you are hot and helping to maintain your body heat when you are cold.

How can Memory foam help me?

Memory foam is particularly helpful to all of the joints and muscles in your body. As the memory foam eases the pressure points of your body it also helps to prevent common complaints that can arise from sleeping in a difficult position. With memory foam the reactive foam moulds to whatever shape you are in, offering you the same level of support regardless of your sleeping position.

What problems can memory foam help and/or solve?

Memory foam was released for medical use after its popularity with Nasa, and the Doctors could see how the foam would benefit its patients. The reactive body contouring foam helped prevent pressure or bed sores to long term patients. It also showed considerable improvement with people who suffered with arthritis, rheumatism, scoliosis, sciatica, blood clots and varicose veins. As well as easing some of these medical issues memory foam has been shown to significantly improve common issues associated from lack of sleep such as; migraines, acne, menstrual problems, headaches, lethargy, joint and muscle pain and back problems.

What’s it been used in?
