they’re used to make mattresses, beds and toppers. Just confused if visco-elastic foam IS polyurethane or it’s a completely different thing entirely.
Polyurethane foam is a material that was engineered during World War II by Professor Dr. Otto Bayer to replace more expensive natural resources like rubber. Rapidly expanding beyond the war uses it was initially designed for, polyurethane foam today is one of the more wildly used materials around. The diversity of uses is also impressive – polyurethane foam can be found in everything from medical research labs to the cushions in your couch or chair. Polyurethane foam is also finding a use in economy mattresses because of its long-lasting comfort and affordability, as well as a way to reduce the costs of memory foam or latex foam mattresses by being used as a base. Polyurethane cushion foam is known as Qualux Foam for premium uses and Resilitex Foam for more economy uses.
Visco Elastic Memory Foam is a material NASA engineered to make astronauts more comfortable during space launch. It is sensitive to the heat the human body emits and has the ability to automatically adjust to body weight and temperature. The result is a luxurious sleeping experience, not only because Visco Elastic Memory Foam removes irksome pressure points that interfere with a restful sleep, but also because Visco Elastic Memory Foam aims to relieve aches and pains that can accumulate throughout the working day. Visco Elastic Memory Foam is considered medium in firmness and responds to your body´s pressure and temperature. It conforms to the curves of the body, offering support along the spine with no discernable pressure on bones and joints. Because of this lack of pressure, circulation is encouraged during sleep making it easier and even preferable to sleep in the same position for hours at a time. Visco Elastic Memory Foam also reduces the effects of tossing or turning from a sleeping partner!
Viscoelastic foam, also known as memory or temper foam, was first commercialized during the mid 60’s as a result of NASA’s AMES Research technology transfer program. This open-cell variety of flexible polyurethane foam (FPF) was distinguished by properties allowing it to redistribute the G-Force suffered by astronauts during take-off and re-entry, and providing commercial pilots a more comfortable seating surface during long flights.
