What is memory foam mattress made of.

A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam. Memory foam molds to the body in. First designed in the mid 1960s for nasa airplane seats memory foam is made from a substance called viscoelastic. Memory foam is a chemically produced synthetic mattress foam not too dissimilar to other foams you may have around the house.

Viscosity the material moves slowly and reluctantly when pressure is applied. Memory foam memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. Memory foam mattresses are made of polyurethane which was initially created for nasa but has since evolved into one of the most common materials used in furniture. It s also called viscoelastic which combines two concepts.

Memory foam is what is known as viscoelastic polyurethane foam or low resistance polyurethane foam lrpu. It is created by adding various compounds and additives to polyurethane which change depending on the type of foam being created. Greener versions of memory foam use plant based ingredients like soybean oil in place of some of the petroleum derivatives memory foam s distinguishing feature is that it softens in response to heat and pressure. The foam bubbles or cells are open effectively creating a matrix through which air can move.

It s now used in a variety of mattresses from casper simba leesa to eve. The difference is that memory foam is viscoelastic or reacts and softens when subjected to heat. It is often referred to as viscoelastic polyurethane foam or low resilience polyurethane foam lrpu. Ultimately these chemicals affect two of the main qualities of memory foam.

Depending on the chemicals added and the way it is processed polyurethane can form anything from car parts to spray liner or in this case one of the most comfortable sleeping surfaces the world has ever seen.
