Check the Memory Foam Density

Density is measured in cubic metres (m³), so the higher the density, the heavier the mattress will be. As a general rule, the higher the density of the memory foam, the better the quality.

While most sleepers prefer a mattress that’s at least 10 inches thick, mattress thickness depends on personal needs and preferences. A thicker mattress may be better for side sleepers, individuals over 90kg, and those who find it easier to get in and out of a higher sleep surface.

A 40 density would be high density in polyfoam (PU Foam), not so much in memory foam, and very low for others. For example, in the Indian demographic, people prefer the PU Foam to have a density value between 32 and 40. Similarly, memory foam should have a density value between 50-60 and between 55-65 for latex foam.

Foam density is the mass of a foam’s material within a cubic foot. The denser the foam, the more compact the foam material is. This, in turn, makes the foam heavier. A foam’s density is characterized by pounds and is determined by taking its mass and dividing it by its unit volume.

Although memory foam is generally considered safe, it may pose a problem for certain people, such as those who suffer from allergies, asthma, or other respiratory conditions. Memory foam may also bother you if you are very sensitive to smells.

There’s a misconception that high-density foam and memory foam are two mattress types that can be directly compared. In truth, high-density foam refers to the amount of foam per square foot of a mattress, while memory foam is a type of foam and comes in different density levels, from low to medium to high.
