Introduction to Memory Foam

Memory Foam Mattresses-

Memory Foam History-

Memory Foam was developed by NASA in the late 1960’s to improve safety of aircraft cushions.  Memory foam is firmer when cold, and reacts to body heat, allowing it to conform to the user.  NASA released the technology to the general public in the 1980’s.  Fagerdala World Foams was one of the few companies to work with the foam and in 1991 they debuted the “Tempur-Pedic Swedish Mattress”.  Some of the first uses were medically related for patients who had to lay in a set position for unhealthy periods of time.  Tempur-pedic memory foam mattresses cut way down on bed sores and gangrene.  Originally the technology was too expensive for widespread use, but that has changed in recent years and Memory Foam mattresses are much more common today.

Memory Foam Properties-

Memory foam mattresses are usually more dense than other types of mattresses, making them more supportive but also heavier.  Memory foam mattresses are often seen as a compromise between the comfort of a soft mattress and the solidness of a firm one.  These mattresses often sell for more than a traditional mattress.

Memory foam reacts to heat and weight and will mold itself to the sleepers body, relieving pressure points and sore spots.  The density of the mattress is measured in ‘pounds per cubic foot’  and a density of 5 lb/cft is generally considered high quality, although most standard foam has a density of 1 to 5 lb/cft.

Though occasionally a mew memory foam mattress will give off odors, the odors tend to decrease over time and with airing out.  Memory foam is very resistant to bacteria and dust mites and are generally good for those sleepers suffering from allergies.
