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.
Orthopedic is a term that in the context of mattresses means supporting joints, bones, and the overall body. It is commonly used for mattresses that help with spinal alignment and recovery from joint or back issues.
In this way, there is no one material that is certified orthopedic, and the term can be used my manufacturers and marketers to help sell their mattresses.
For this reason, it is important to do additional research on any bed that claims to be orthopedic to make sure that it will actually help straighten the spine and alleviate pain.
Pros: For mattresses that stand true to the name, pain alleviation and better posture are some of the benefits.
Cons: It is difficult to decipher the truth from marketing on orthopedic mattresses.
