High Density Foam vs. Visco Elastic Foam

High Density Foam

High density foam is a very firm foam that generally makes up the bottom layer of popular memory foam mattresses. Other types of mattresses such as innerspring or hybrid may also use high density foam to support the spring systems.

High density foams generally are not used to create the entire mattress because they are just too firm. So, generally they are used as a foundation for the bed or to provide edge support.

High density foam is made of a blend of polyurethane and has a tendency to off-gas. If you are susceptible to lung issues, please do additional research on the quality of foams before purchasing.

Pros: Structural firm foam used by many mattresses to provide foundation and shape.

Cons: Off-gassing problems with lower quality foams and it is too firm to make a mattress in its entirety.

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.
