Foam Density and Why You Should Care About It

Foam Density and Why You Should Care About It

By: David Keam

President of the Best Sleep Centre

At Best Sleep, we take sleep seriously. All of our Restonic and Spring Air Mattresses are engineered with the latest in Comfort Technology. In this blog I would like to discuss Foam Density and why you should care about it.

Foam density is a key factor in determining quality, durability, and overall mattress. If you have ever heard the idea that your metal spring coils sagged? Of course not, because it is not possible. Unless you are standing on your bed to change the light bulbs or letting your kids jump on the mattress like in some silly hotel commercial; your coils are as good as the day they were made. It is the foam that sags and eventually turns to powder.

If a company offers you 1000 pocket coils and 1.5lb. foam and another mattress store offer you 2000 pocket coils and 1lb. foam take the 1000 pocket coil bed. If you want a fantastic quality bed, then come and see our Scion mattress by Spring Air (LINK) with 5000 pocket coils and 1.8 inches of 4lb. foam. Now you have the absolute best and will be a satisfied customer for the next 10 years… or more.

Now for the specifications: Mattress foam density is expressed in pounds and refers to the mass of one cubic foot of foam (i.e. a 5-pound per square foot piece of foam means that a 12”x 12”x 12” cube of the foam weighs 5 pounds). A mattress with a layer of higher density will be heavier and be more solid and last longer than a mattress built with lower density foams. It is important to note that the density of a foam layer is unrelated to mattress thickness or firmness. Density is a quality best tied to durability and posture support. The foam in mattresses comes in three densities: low-density, high-density and ultra high-density.


Low Density

Low-density foam is typically measured at 2lb/ft³ or lower. Many other mattress brands now primarily use this density level because of its lower price point. However, the lower density equals a shorter life span, less durability and less overall support than higher-density models. The base line of many mattresses is 1.35lb. per sq. foot. These mattresses often soften much quicker, which results in sleepers sinking through the mattresses top layer. For heavier sleepers or those who are prone to body pain, this lack of support is not good.

  • 1lb. to 1.35lbs.
  • less durable
  • lower price point
  • decreased support


High Density

High-density foam falls within the range of 2.5lb. to 3lb /ft³. These designs offer an ideal mix of durability and support at a reasonable price point. The higher-grade memory foam will support increased bodyweight and improve mattress integrity and longevity. These higher destiny foam infused mattresses aid to shape to the contours of your body, leading to better body support in key areas such as the back, shoulders, and hips. High-density foam also provides an ideal balance between adequate airflow and long-term durability.

  • 0lb. to 3lb.
  • exceptionally durable
  • longer lifespan
  • excellent overall support
  • cost-effective
  • reduced pressure points


Ultra High Density (Our Scion Mattress – LINK)

  • 4lb. or higher
  • exceptionally durable
  • high price point
  • longer lifespan
