35-density foam should not be compared with HR foam types. The main feature that distinguishes 35-density foam from HR and 35-density white foam is that it has a much firmer structure.

Description

Density in sponge is a term that generally refers to the material’s density. As the density increases, both density and quality increase.

Foams used in sofa cushions range from 28 DNS up to 40 DNS. The higher the foam’s DNS, the longer its lifespan. For example, a 28 DNS foam may thin by 2–3 cm per year, whereas a 35 DNS foam maintains its shape.
