Memory foam is known for its ability to conform to your body shape and support your joints, thus alleviating aches and pains. But even if you’re ready to embrace this material, you might be
unsure of how thick your memory foam should be.
You’ve come to the right place. To choose your perfect mattress, it’s important to consider not only the memory foam mattress thickness but these additional four factors: the mattress layers, how much support it offers, its density, and how firm it is.
Use this helpful guide to find a memory foam mattress built for you to drift away on.
Curious to know what thickness memory foam mattress you need to get? They can range anywhere from 8-14 inches. Typically, the standard mattress thickness is 10-12 inches, which is enough to conform to the body of the average adult sleeper. Thicker mattresses are another way to gain additional support.
If you’re wondering what thickness memory foam mattress is best, these factors can influence whether you should try an 10-inch thick mattress or a 14-inch thick mattress:
If you need more support, opt for a thicker mattress.
While thickness is a great place to start, you’ll need to do a little research on your potential mattress to ensure it meets all your sleep needs.
So, how many layers does a memory foam mattress have? Depending on the brand and manufacturer, it can vary, but the answer is typically two: a comfort layer and a base layer.
Sometimes these mattresses can come with a transitional layer that is in between the comfort and base layer. That middle part acts as a “buffer” and also helps to prevent sagging.1
What thickness memory foam mattress topper is best for you depends on your desired firmness and support, but one thing is for certain: you need more of the base layer than the comfort layer.
To determine if the mattress has enough support, look at the base layer.
As mentioned before, this layer is what holds everything up including you. That means it should be at least twice the size of your mattress. If your comfort layer is two or four inches, then make sure your base layer is at least four to eight inches. Depending on your body type and other factors, you may want to choose a thicker mattress.2
Sufficient support promises to prevent your bed from sagging. Plus, a good, durable base layer will ensure your mattress is in it for the long haul.
Have you ever considered your mattress’ density?
As we’ve explored, thickness is not the only factor in support.
The higher the mattress density, the more it can support your body. The density of a memory foam mattress is measured in pounds per cubic square foot, or PCF.
While low-density mattresses are more lightweight and cheaper compared to the others, higher-density mattresses offer more support and durability. So, it’s best to go for a mattress that is at least medium-density. Anything lower can heighten your neck and backaches as well as break down sooner.
The density chart for a polyfoam mattress will look different, so double-check to see if the mattress you’re looking at is polyfoam or memory foam.
While you might assume that density is the main measure of mattress firmness, there is in fact yet another number to add to your mattress calculations.
If you want to know how firm a mattress is, look at its Indentation Load Deflection (ILD) rating. In the mattress business, manufacturers figure out how much pressure a mattress can take before it indents four inches into the surface.
A high rating indicates a firm mattress, while a low rating indicates a soft mattress. Choose the option that best suits how you sleep.
