What Is Mattress Density?

Mattress density is exactly what it sounds like: the density of the mattress. You may also hear other terms like "foam density," which essentially mean the same thing. The denser your mattress or the foams used in your mattress, the heavier and more solid it will feel per volume.

So if you want a heavier, more solid feeling mattress then you'll want a higher density. If you want a lighter, more airy feeling mattress then you'll want a lower density.

How Density Affects Weight and Durability

When considering which type of memory foam mattress is best for you, it's wise to pay attention to the density of the memory foam. Density is a measurement of the weight of the memory foam per volume. The density of the foam determines many of the characteristics of the mattress, and you can often learn a lot about a memory foam mattress just by knowing its density.

Generally, denser memory foam is more expensive and of higher quality. If a memory foam mattress is surprisingly cheap, it may be because it is made from a cheap, low-density foam that won't last as long or perform as well.

Levels of Density

The price of a memory foam mattress is often linked to its density. The denser a memory foam mattress is, the more expensive it usually is. Higher quality brands use higher-density foams (5 pounds or more per foot), medium-priced brands typically use medium-density foams (4 pounds per foot), and budget or low-priced brands use lower-density foams (2.5 - 3 pounds per foot). The durability of a memory foam mattress is also linked to the foam's density. On average, the higher the density of the foam, the greater the durability of the mattress.

Mattresses that contain high-density foams are typically expected to stay comfortable and supportive for at least 10 years. Memory foam mattresses that are made from lower density foams have a shorter lifespan, and typically don't last longer than 8 years.

Regardless of density, all memory foam mattresses excel in relieving pressure points that cause back, shoulder, and hip pain. However, higher-density foams tend to be more effective. Higher-density foams also typically contour better to the curves of a sleeper's body, which results in greater support and better alignment of the spine.
