What is the Thickest Memory Foam Mattress?

Thickness is the most important thing in the mattress because it tells you how long the mattress will last with you. The thickness of the foam depends on your weight. If you are a tall, bulky guy, you need a thick mattress covering your body because a thick mattress has more layers. 

What is the thickest memory foam mattress?

The thickness of the mattress varies from 6 to 14 inches. If you want a mattress for your children, then a thickness of 6 to 10 inches would work for you, but if you want a mattress for adults, then the thickness of the mattress that suits you is above 10 inches. 

The thickness is for your comfort and relaxation because more thickness will help you get better sleep which you will not get on a thin mattress. 

Difference Between the Thickness of the Memory Foam Mattresses?

We don’t have to put a lot of effort to find the differences between the thickness of the mattress. We have already told you that the thickness of the mattress is around 6 to 14 inches. If you want to know the difference between a 6 inches mattress and a 14 inches mattress, then let’s find out. 

If we talk about the 6 inches thick mattress, then it has some layers that would handle the weight of children, and the same goes for the 8 inches mattress, but when the thickness increases to 10, 12, or 14, that means there are more layers added to that mattress to handle the weight of an adult man. 

The thickness is important for the long life of the mattress, but it is also perfect for the person’s comfort. If an adult uses a less thick mattress, he compromises his comfort and relaxation, and the life of the mattress will also be reduced.

How to Choose a Memory Foam Mattress?

Okay, so, you know the difference between the 6 and 8 inches mattress; now let’s find how we choose the memory foam mattress and what things you should consider to choosing a mattress. 

How to Choose a Memory Foam Mattress

Choose the Most Comfortable Memory Foam Mattress for Your Sleeping Style

Every person has a different sleeping style, but four sleeping positions are way more popular, and other positions lie in them too. There is a space between you and your mattress while sleeping that the mattress has to cover, and a good mattress covers that space and gives you a very comfortable space. There are four main sleeping positions, and let’s find out how these mattresses are good for every position. 

Combination Sleepers

These are the hardest sleepers because they don’t find comfort in every mattress. In addition, these sleepers do not have a position; they used to change their positions daily and rotate all over the bed. This sleeping position needs a good mattress for comfort, and memory foam is the best option. 

A medium to medium-firm mattress is the best option for them because it adjusts according to their positions and gives them very firm support and comfort level, which is very important for good sleep. 

Side Sleepers

It is also a very common type of sleeper that sleeps on the weight of their shoulders and hips, and these two are their main pressure points while sleeping. The memory foam mattress comes with a conforming ability that relieves these pressure points and helps you get better sleep. 

Back Sleepers

These sleepers are very hard to find good sleep with all other ordinary mattresses out there in the market. These types of sleepers need a very firm mattress which is provided by memory foam mattresses. The memory foam maintains neutral spine alignment and gives you good support to have a peaceful sleep. 

Stomach Sleeping

According to the doctors, this is a very unhealthy position of sleeping, but still, some people are addicted to sleeping in this position. The people who sleep in this position have more chances to get back pain. 

If you are also one of those who sleep this way, then you should try the medium-firm to firm memory; it may help you to get better sleep at night, but we would suggest you change your sleeping position as soon as possible; otherwise, you may have some harmful health impacts.  

Choose a Memory Foam Type

Most people think that all the memory foam sleepers are the same, but they are not real, and there are some differences in all of them that an observer could see, and after reading this article, you will be able to detect them too. There are three types of memory foams:

Choose a Memory Foam Type

  1. Traditional foams
  2. Gel foams
  3. Latex foams

1. Traditional Memory foams

It is the most common type of memory foam. It supports your body and weight in every shape and makes sure that you have a very peaceful sleep at night. 

2. Gel Memory Foam

These inserts reduce pressure similar to those used in shoe inserts. In addition, the gel encourages air to go through the mattress and disperse heat away from the body while sleeping. People who are prone to sleeping hot find gel memory foam to be a great choice.

3. Latex Foam

There is no technical distinction between this and memory foam, and it does not conform as well to a sleeper as memory foam, but it is plush and comfortable nonetheless. Also, having hypoallergenic and antimicrobial properties makes latex foam a great option for people with dust allergies. In any case, if you have a latex allergy, then you should not purchase a latex mattress.

Compare Memory Foam Density

It is a technical term, so you all might not know about this, but the density measure is between the pounds per cubic square foot. If you want to understand how density affects the body, you should know that the density of the foam decides how it will support the body. The difference in density between the memory foam and poly-foam PCF is very low. 

Memory Type foam 

Memory Foam Type



2.5 PCF to 3.9 PCF


4.0 PCF to 5.4 PCF


5.5 PCF and higher

Poly Foam

Poly Foam Type



1.8 PCF and lower


1.8 PCF to 2.5 PCF


2.5 PCF and higher

One cubic foot of foam has a density of one pound. High-density foams are more durable, but low-density foams are more breathable and lightweight. 

Adaptable high-density foam offers better body contouring but may restrict airflow. In addition, low-density foam tends to lose its structural integrity over time, whereas high-density foam retains its strength longer.

Determine How Thick Your Memory Foam Mattress Should Be?

Plus-sized sleepers may be able to extend their mattress’ lifespan by paying attention to its thickness. Those with heavier bodies need more support; a thin mattress does not have enough layers to meet their needs. Between six and fourteen inches is the average thickness of a memory foam mattress. Children should not be placed in beds 6 to 8 inches high. The reason behind this is simply to benefit adults more.

Determine How Thick Your Memory Foam Mattress Should Be

An excellent mattress for adult sleepers measures 10 to 12 inches. At least two inches of comfort layers and a six-inch base of support should be present at this height. Your body will feel supported by this thickness range. The thinner the bed, the more likely it is to sag and lose its support.

Consider Hypoallergenic Memory Foam

Some people have allergies to different particles like latex and some other thing so, if you have any kind of allergies, then you should go for the hypoallergenic memory foam because these foams save you from different types of allergies which if you don’t consider first you will be in a terrible condition. 

Select a Mattress Size
