History of Memory foam mattress is attached with NASA, Ames Research Center. NASA has invented memory foam for get relief from back pain, neck pain of astronauts which is caused by g-forces in the 1970s. NASA supposed that this memory foam would be used for get comfort to contour of body. By this wonderful foam, people come out from this problem. At the end, inaccurate stress points will be fashioned on the body. After that NASA has invented the way for creating this foam which is comfortable to body contour.

Memory foam is Synthetic polyurethane foam material. Memory foam mattress producers will insert many types of chemicals to modify the density of the foam. After this process, this foam of mattress will have more density. Also they add visco elastic foam material which is non toxic. The weight of foam is depended on the quantity of chemicals which are used in process of the foam. Average weight of memory foam mattress is 4 – 5lb to 2-3 lb.
Quality of memory foam mattress is depended on some factors including ILD raing, resiliency and etc. The Indentation Load Defelection (ILD) is a rating system that is used to verify the resistance of the material. Mattresses with higher ILD rating are hard. Mattresses with low ILD rating are capable to decrease the stress points. Although that, mattresses that are too flexible are not fine for the body. The resilience rating is used to resolve how many recover of steel bound on the mattress. High resiliency designates that the memory foam mattress is very strong. Costly memory foam mattresses are finished from a mixture of the memory foam and lower high resilient layer. The lower high flexible layer and memory foam are capable to decrease the pressure point and propose extra support for the lower part of the body.
