Foam density is a unit of measurement that dictates how many pounds polyurethane foam can support per cubic foot. In short, foam density tells you the strength of the foam, and that decimal you’re seeing is the number of pounds each cubic foot can hold.
Mattress foam density is the weight of one cubic foot of a particular type divided by its volume. … 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.
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.
|Mattress Density||Weight per Cubic Foot||Best For|
|Low||3 pounds and under||Lighter bodies. Side and back sleepers.|
|Medium||4-5 pounds||Average bodies. Side, back, and stomach sleepers.|
|High||5 pounds and up||Heavier bodies. Stomach, back, and side sleepers.|
If a product has a 2 lb. density, that means a 12″ x 12″ x 12″ foam block weighed 2 lbs. Although density does not pertain to the firmness of a foam cushion, it does correlate to the quality and longevity of that cushion.
2.5 to 3.5 pound density foams are the High Quality materials people should look to when they have a heavy-duty application that needs to hold up to use for years. These products last longer and are able to bear more weight and diffuse impact better than lower quality materials.
Latex foam is one of the most durable types of foam available. Latex mattresses and mattress toppers long outlast those made with memory foam and polyurethane foam. We often hear stories from customers that have had latex mattresses last over 20 years.
Just like almost every other substance on the planet, polyurethane foam off-gasses, or releases compounds into the air. Yes, you breathe in these compounds when you sleep on these mattresses. But no, they’re not going to hurt you.
A higher density foam mattress will offer firmer support, thus keeping you on top and allowing more air to circulate around you. So, if you want to sleep in a cooler environment, choose a high-density foam mattress.
This high density foam provides the most support. It is best used in frequently pressured cushions, chairs, and mattresses where the foam will withstand constant pressure from sitting while still keeping you comfortable.
D30/D35 – Specialised foam
They are generally grey in colour and are exclusively made by Plyfoam. These foams have a high resilience and densities between 30kg/m 3 and 35kg/m 3 .
Firmness is an indicator of the surface feel of the foam. It is measured using the force in pounds required to indent a foam sample by 25% of its original height. This measurement is called Indentation Force Deflection (IFD).
To calculate the density of a piece of foam, you divide the weight of the foam by its width x height x length. If you measure in feet, density is expressed in weight per cubic foot. Say the density of a mattress is four pounds per cubic foot.

High density foam is a very firm foam that generally makes up the bottom layer of popular memory foam mattresses. … High density foams generally are not used to create the entire mattress because they are just too firm. So, generally they are used as a foundation for the bed or to provide edge support.
Memory foam mattresses are often touted as the best option for back pain, and they can certainly be beneficial, thanks to their balance of support and cushioning. However, it’s key to purchase a mattress made with high-quality, dense memory foam, which will provide the support you need.
The ILD rating of a foam material will tell you how FIRM the foam is. Some people prefer a very firm cushion, while others prefer softer. We offer firmness levels of Soft, Medium, Medium Firm, and Firm to match the preference of each customer.
A 5″ thick foam core made with 1.8 density HR (High Resiliency) foam can be expected to last about 3 years with average use before the foam begins to lose its ability to bounce back and keep its shape. Foam cushions will typically still be usable for another couple of years after the deterioration process begins.
Higher-density foams are especially good for pain and pressure relief. … Higher-density foams are especially good for back and stomach sleepers. The fact that they don’t sag quickly means, they offer great back and neck support.
The key to reducing off-gassing odor is ventilation and time. Give your mattress plenty of time to air out in a well-ventilated room. This ensures your bed can release the majority of its off-gassing odor before you sleep on it for the first time. Many new mattresses need at least a few hours to air out.
