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.

Gel

Gel is a recent newcomer to the mattress space. It is being used as both a standalone layer and an infusion into foam. Gel benefits mattresses by retaining less heat than memory foam. Also, newer gels compete against memory foam by being more responsive and less toxic.

Gel is similar to foam because it is a polymer made by blending plastics and other chemicals.

Because of gel's heat diffusing properties, it is generally found in the top layer of the mattress under the cover.

Pros: Cooler sleeping surface vs memory foam. More responsive feel when not combined with foam.

Cons: Similar to foam, it is a synthetic blend of chemicals.
