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.
Latex is made from the sap of a rubber tree. Over generations, people have learned how to tap the trees without having to cut them down. This means that it is one of the most eco-conscious and sustainable ways to create bedding.
After the latex is harvested from the rubber tree, it is treated to create foam. The two most common ways of treating latex for bedding is Dunlop and Talalay. The result is a high response and heavy piece of foam that can be used for bedding. By changing the density, the latex can be more or less responsive.
Those that are used to a memory foam feel (a slow response) will be surprised to know that most latex is highly responsive, meaning that although it will react to ones body, it has a natural bounce. Some sleepers prefer this, though others not so much.
Recently, there has been an explosion in latex bedding with the higher demand for eco-conscious foam alternatives. Though latex is natural, there are some that mix it with memory foam. For those that are looking for pure latex bedding, be careful to do your research on the entire bed.
Pros: High response, differing firmness options.
Cons: High expense vs memory foam, some don't like the latex responsive feel.
