Memory Foam Density
Memory foam mattresses are often sold for higher prices than traditional mattresses.
Memory foam density. Memory foam used in mattresses is commonly manufactured in densities ranging from less than 1 5 lb ft 3 24kg m 3 to 8 lb ft 3 128kg m 3 density. Most standard memory foam has a density of 1 to 5 lb ft 3 16 80 kg m 3. Memory foam density is measured as mass per unit volume. The measurements are 12 inches x 12 inches x 12 inches.
Beds with high density foam comfort layers and support cores typically weigh 75 to 90 pounds or more in some cases. For memory foam the manufacturer takes a piece of foam that s one cubic foot. Low because low density foam is relatively inexpensive mattresses with this material have the lowest average price point. For instance what you often see is a mattress with a low density.
About 500 to 750. If you have a memory foam mattress with a density of 5lbs per cubic foot the foam will weigh 5lbs per cubic foot of course. It has low density and a shorter expected lifespan than memory foam but it still conforms to your body to relieve pressure. Simply put the denser the foam the more foam material used in a given area and the heavier that foam is.
You should also know that most memory foam mattresses have several layers so they can benefit from the different density characteristics explained below. Polyurethane foam is a low cost substitute for memory foam. Low density memory foam weighs 3 pounds or fewer per cubic foot. Due to its construction memory foam is denser than other standard polyurethane foam making it more supportive and durable.
For you visual learners it s represented by the equation. They re quick to respond to your movements because they contain more air.
