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.

Wool

Wool is made of sheep fur. It is sheared from the sheep multiple times in their lives.

The most famous kind of wool being used in mattresses is New Zealand wool because of its attention to quality.

Wool is commonly found in the cover or as a comfort layer. As a comfort layer, it is packed tightly in the mattress so it can add softness to the top layers of the mattress. Some untreated wool may have a slight natural barnyard smell. It is also a natural fire retardent.

Pros: Wool is an all natural alternative to other types of comfort layers.

Cons: The quality of wool bedding is entirely dependent on mattress craftmanship. If the packing is too loose, there can be quick sagging and durability issues.
