Memory foam is a soft supportive foam which reacts to body heat to mould around the body and provide support to the body. It consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density.
The foam bubbles or ‘cells’ are open, through which air can move. Its typical early use was made by the space programs and the medical industry, for its unique supportive properties.
Developed by NASA in the USA in 1966 to improve the safety of aircraft cushions. The temperature-sensitive memory foam was initially referred to as “slow spring back foam”; most called it “temper foam”.
In the early 1980s, NASA released memory foam into the public domain, later commercialisation of the foam included use in both medical equipment and sports safety equipment.
The production technique for memory foam was initially too expensive for widespread use but became cheaper over the years. Its most common domestic uses are mattresses, pillows, shoes and blankets. It has medical uses, such as wheelchair seat cushions, hospital bed pillows and padding for people suffering long-term pain or postural problems.
Memory foam was subsequently used in medical settings. It was commonly used in cases where the patient was required to lie immobile and the old-style firm mattresses available at the time, were impaired the blood flow to the region, causing pressure sores or gangrene. Use of memory foam mattresses significantly decreased such events
