What does the density of memory foam mattress mean?

Comments

The density of a memory foam mattress refers to the weight of the foam within the mattress in units. Foam density is calculated by Indention Force Deflection and is measured by kg per metre cube (kg/m3). If the IFD is higher in memory foam, it will be more firm and supportive to your body’s pressure points. Many people have a misconception that the density of memory foam mattress is linked to the durability of a mattress, which is not true. The durability of a high quality memory foam mattress has no link with the density. The choice of different densities is to accommodate people with different weights with the same level of firmness and support. Picking the right memory foam mattress can be quite difficult and confusing due to the high number of different types of memory foam mattresses. It is for this reason I have written this blogpost to help you understand variations in the density of memory foam mattresses and their respective qualities. I want to try simply the various types available to ensure you choose the right density of memory foam mattress.
