Density is the most frequently spoken-about characteristic of a memory foam mattress. In general, greater quality beds are made from greater density foam and buyers who browse mattress review providers like look to density as a way of examining quality in a mattress. High-density memory foam beds are more pricy because they have more foam per bed, but they provide much better support and more sturdiness.


Determining high-density foam includes weighing a sample of foam, determining its measurements, and utilizing the information to compute a value revealed in pounds per cubic foot (pcf). Memory foam beds range in density from 2.5 pcf to 6.0 pcf. It prevails on the market place to reveal density merely as a number of pounds (pound or pounds). A 5lb high-density foam mattress suggests a foam density of 5 pounds per cubic foot.


Foam makers commonly relate to foam density as the primary reason identifying the resilience of a high-density foam mattress. Sturdiness is the capability of foam to maintain its initial comfort and support qualities. In basic, greater density beds are more resilient. They are also more pricey to produce due to greater product content.


Density and Firmness


The most typical misunderstanding about memory foam mattresses is that density is relative to firmness. Density is not straight reliant on firmness. A 5-pound density memory foam mattress can be softer than a 3-pound density memory foam mattress.


Foam firmness is revealed as an ILD (Preliminary Load Deflection) score. ILD ratings range from 10 – 16, greater numbers being more firm.


The Perfect Density for a Memory Foam Mattress


Foam is comprised of countless small cells. The cells are formed by a polyurethane wall and filled with space (air). Greater density foams have thicker cell walls and less space inside. Lower density foam has thinner walls, greater space. If foam were made too thick, its cell walls would be too thick/ stiff. It would be tough to the touch and would not adhere to the body appropriately.


It costs more making thick foam, and at some time it can be made too thick. There is a balance that needs to be struck in between efficiency, expense, and resilience. The market today has collected around a 5 pound memory foam mattress as the ideal option for bed linen. While more costly than lower density foams, it offers much better, long term contouring support.


Memory Foam Mattress Base Foam


Many individuals wrongly believe that memory foam beds are made with only memory foam. However, only the top layers are made of memory foam while the base layers are made of conventional closed-cell, polyurethane foam. The function of the base foam is to add cushioning support to the memory foam layers. The base foam varies from 1.8 pound to 2.5 pound, but because it is a different kind of foam, it is normally more resilient than the memory foam it is coupled with. It is less thick than memory foam, yet much firmer, varying from 20ILD to 40ILD for the different base layers.
