High-Density Foam: What it is and why it may be the Solution to Your Sleep Needs


High Density Foam

If you’re in the market for a new mattress, there are a few things you’ll want to know so you can be sure you’re making an informed purchase. When it comes to your mattress, the quality of the materials matter. Nowhere is this more evident than with the foam itself, deep inside your mattress. This is the sleep surface you’ll have for the next decade, and not all foams are created equal! You want high-density foam. What does “high-density foam” really mean, though? To put it plainly, it means there is more foam and less air in the mattress. 

High-density foams are foam with high weight per cubic foot and therefore have a strong cell structure, which makes the material highly durable. This does not have an effect on how soft or firm the mattress is. Density only indicates quality and durability, not your comfort level. Since the majority of mattresses use polyurethane foam, it's important to understand the concept of density in relation to this. Premium foam is considered at a 1.5 density or above. Some characteristics of premium foams are Depth of Feel and Flex Fatigue. With that in mind, let’s look at exactly why this type of material is better:

High-density foams last longer

You could easily buy a less expensive mattress with low-density foam, but you should not. Why? Because it won’t last as long feeling the way it does on your first night. After all, you intend to keep this bed for years to come, so quality matters. More air in the foam means a much greater chance of it feeling flat sooner than you would like. Your new mattress will maintain its feel for a longer period of time if you remember what you learned about premium foam having a 1.5 density or above when you are shopping.

High-density foams have less chance of settling

High-density foams settle less often than lower-density foams. High-quality materials have a higher recovery and less possibility of body formation. This compression ability means you won’t have to worry about premature body formations the way you would with a lower-quality substitute. In fact, some people describe sleeping on a high-density foam mattress as feeling as if they are “floating.” A great way to understand this density is to think about baking a loaf of bread! A home-made loaf of bread is usually heavy or dense, having more yeast than air. In comparison to a grocery store loaf of bread off the shelf, it's more lightweight, having more air than product

High-density foams promote better sleep

High-density foam provides better pressure relief and allows you to more easily enter Deep Sleep and REM. High-quality, dense foams conform to your body, which diminishes uncomfortable pressure points while you sleep. As you stay comfortable, your body is able to go through your entire sleep cycle, spending time in both Deep Sleep and REM. Without quality sleep that regularly cycles through all stages, you can’t heal as well, or form or maintain the pathways in your brain that allow you to learn and create new memories, and it’s harder to concentrate and respond quickly. If you think you’re waking up too often throughout the night and therefore not entering REM the way you need to, a better-quality mattress can often help.

High-quality foam, as well as other premium raw materials, is uniquely made for your body’s individual curves. It is found in three places: the core, comfort layers, and quilt package. The core of a mattress is so very important toward how long it lasts, as mentioned above. It is your support layer, and you want as dense of a core as possible to give you both support and extended durability. The comfort layers should also be of high quality to offer comfort and also add to the support of the core. The quilt package, sometimes called an upholstery package, is typically different layers of polyurethane foam that are quilted together to offer breathability and air-flow. All of these are designed to work together in order to offer maximum pressure relief and deliver a deeper, more restorative sleep every night.
