Does Flexible Foam Density Determine the Firmness and Quality of the Cushion?
The more material (denser the foam) that goes into producing a foam size will provide more support, however, this is independent of the surface firmness. High density foams can be produced to be very soft and low density foams can be made to be very firm. The density of the foam will dictate the level of support of the cushion and it’s ability to push back so it will feel less like the cushion is bottoming out. Usually support densities of 1.8 and greater will be needed for a furniture seat cushion to bear the appropriate amount of human weight and retain its original properties to a more satisfactory level.
