There are a few terms in the bedding industry as ambiguous as foam density. It is a term marketed widely on the majority of beds. Even Spring coil mattresses consist of high-density foam. However, what does it mean, and what effect does foam density have on a foam mattress?
Foam Mattress Density is a measurement that compares the amount of matter the foam has to its volume, usually expressed in kilogram per cubic meter (kg/m3). In simple terms, if you weigh a 1m x 1m x 1m block of foam, the weight of that block will indicate its density.
The higher the density, the more raw material is used to produce the same size of foam compared to a less dense foam, hence the increased price. A higher density foam mattress means higher quality and durability and should not be confused with firmness. One can have a very high-density rating in foam, and it can be as soft as a very low-density foam.
Another aspect that adds to the confusion of foam density is that some manufacturers add fillers to the foam. These fillers artificially increase the density of the foam without the quality and durability that goes with such an increase. It is therefore essential to note that Sloom uses pure foams without any fillers on our foam mattresses.
