Foam vs. Visco Elastic Foam
Foam
Mattress foam comes in multiple different types: memory foam, polyurethane, and latex. Memory foam is a type of polyurethane foam that has lower resistance so it reacts and slowly reforms when pressure is released. It generally makes up the surface layers of a mattress.
Polyurethane comes in multiple different forms - making it useful in the middle and base layers of many foam and memory foam mattresses.
Latex is the natural alternative to memory foam and polyurethane foams. It is created from sap from a rubber tree and is treated to create different densities to cover both soft and firm requirements. Like rubber, it is highly responsive and has a bounce that some sleepers love and some others hate.
Pros: Depending on the foam type, it can be quite comfortable, safe, and responsive.
Cons: Lower quality foams can break down quickly, causing sagging issues within only a few months or years.
Visco Elastic Foam
Visco elastic foam is another term for memory foam. It is a blend of polyurethane foam that was developed for airplane cushions by a NASA contract in the 1970s.
The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance. Its soft surface allows for contouring and its slow response lowers bounce.
Visco elastic foam, like all polyurethane foam, is made from a blend of substances and has a tendency to off-gas. Those with lung sensitivities should do additional research about the quality of foam to ensure that it won't aggravate them.
Pros: Contouring comfort, competitive pricepoints, and widespread options.
Cons: Sagging and off-gassing problems with lower quality foams.
