Mattress Density: How Important Are They?

Mattress density

If you are shopping for a new mattress, one of the factors to consider is density. Density is the degree of compactness of a substance, thus a mattress’ density determines its thickness or softness. So if you want a heavier, thicker mattress you will want a mattress with a higher density and vice versa. Density does not only refer to firmness, but it also refers to the quality and durability expected of a mattress.

Also, it is important to note that density alone is not an indication that a mattress will be harder or firmer than one with a lower foam density. A dense mattress can provide quite a bit of body contouring and pressure-point relief. The foam Indentation Load Deflection (ILD) is not density, rather, it is what determines firmness as well as how much weight is required to indent it.

As we continue in this discourse, it is vital to state that there is a correlation between a mattress density, overall comfort, and feel.

Here are some of the things we are going to explore regarding mattress density:

Response to Temperature

First, the Higher Density foams tend to be more temperature-sensitive, this means that they take on a rather sticky feel as they warm up. Some sleepers enjoy this feeling of being contoured and cradled, while others feel as though they’re trapped and sinking into the bed. These types of mattresses don’t return to their original shape quickly, thereby making it difficult for people who change positions while they sleep.

On the other hand, the Lower Density foam mattresses don’t react to temperature, in the same way, it returns to shape faster, and cause fewer difficulties for sleepers who move around a lot.

Motion sequencing

The mattress density level is not a signal of the degree of motion. All memory foam densities, whether they are low or high, do well at preventing motion transfer. This is particularly helpful for couples where one person moves around or gets in and out of bed frequently throughout the night.

A high-density foam affords a sleeper more body contouring, the increased density also gives more support, pushing the sleeper upward even as it enfolds their body. A low-density foam doesn’t provide a great deal of support. Little wonder why a higher density mattress rates better for back pain relief than low-density mattress.

A new mattress is a significant acquisition, therefore, durability is an important factor when making a choice. Findings and reviews have shown that mattresses with higher foam density often last longer. This is because denser mattresses don’t soften and break down as quickly as the low dense once.  A higher density support core is also important because once this layer breaks down; the sleeper will begin to experience pain and discomfort.

Subsequently, we shall consider further details you need to arm yourself with when it regards mattress density. No knowledge is indeed a waste, that is why at Winco foam, we have positioned ourselves as your number one sleep expert in the mattress industry.
