To get the right memory foam density chart for your specific needs, you need to understand the high densities and mattress firmness of the foam.
And this is not an easy task to do because there are many different types of memory foam and even more than one kind of each type.
You need to know about each type of memory foam so that you can choose a mattress that will give you the support and comfort you want at an affordable price.
What is Memory Foam?
Memory foam is a type of bed mattress that is made from a variety of materials, including latex, thermoplastic elastomer (TPE), higher densities, and polyurethane.
Memory foam was invented in the 1970s by Dr. James Goodrich and has been used in hospitals and offices ever since because it is durable, comfortable, and supportive. We are now seeing people use memory foam in their homes because of the longevity and durability that it provides.
Some types of memory foam require you to purchase a specific brand, while others do not. While there is some variation between manufacturers, all beds made with this type feature thick layers of organic polyurethane on the topper (2-3 inches) and inside (1 1/4-1 3/4 inches).
What are the different types of memory foam Density Charts?
There are three main types of memory foam: soft, medium-firm, and hard. Each type has its unique characteristics that you should consider when purchasing the best mattress.
Soft Memory Foam Mattress – This type of memory foam is the least supportive and is made from layers of cut-out fill, lower-density foam, and other materials.
It is also the most uncomfortable to sleep on low-density because it allows body heat to escape through the material.
Because the layers of memory foam are so thin and therefore breathable, the bed might move more than a normal mattress would. This can make a side sleeper very uncomfortable for people who have back or hip pain.
Medium-Firm Memory Foam Mattress – Medium-weight materials include polyester fiberfill including medium-density and are denser (thickness) than soft types because it has this type of material on top that adds extra support for heavier individuals.
The same features as the soft memory foam mattress apply to this model as well. When purchasing a medium-firm type, you need to make sure it is paired with another brand of the manufacturer because there are many variations within each category of memory foam.
Hard Memory Foam Mattress – The hardest version of the sleep surface steps up in high-density foam and would be considered one of the most supportive.
If it wasn’t so hot when sleeping on top since there isn’t a layer of high-density memory foam on top.
This is the most expensive type because it offers up to 40 lbs of support, but it may feel too hard for some individuals who have no back pain or stress issues.
Memory foam, a form of polyurethane foam, possesses viscoelastic traits, enabling it to mold to the body’s contours for pressure alleviation. Density, measured in pounds per cubic foot (PCF), defines the amount of material within a foam volume. Density influences memory foam’s durability, price, weight, responsiveness, and contouring abilities.
The table below shows the different categories of memory foam density and some of their characteristics.
| Density Range (lbs/ft³) | Feel & Performance | Pros | Cons |
|---|---|---|---|
| 2.5 – 3.5 | Very soft, conforms deeply, molds to body contours | Pressure relief, good for side sleepers | May lack support, less durable, heat retention |
| 3.5 – 5.0 | Medium-soft, balances comfort and support, conforms moderately | Comfortable, versatile for various sleeping positions, relatively durable | May not be ideal for heavier individuals or those who prefer firmer beds |
| 5.0 – 7.0 | Medium-firm to firm, provides good support, retains less heat | Supportive, good for back and stomach sleepers, more durable | May feel less conforming, not ideal for pressure relief |
| 7.0+ | Very firm, offers maximum support, minimal sinkage | Very durable, ideal for back sleepers or heavier individuals | May feel uncomfortable for side sleepers, less pressure relief |
Additional factors to consider:
- Body weight: Heavier individuals generally require higher-density foam for adequate support.
- Sleeping position: Side sleepers typically prefer softer foam for pressure relief, while back and stomach sleepers may do better with firmer foam.
- Personal preference: Ultimately, the best density for you depends on your comfort level and preferences.
Beyond density:
- Foam type: Different memory foam types (gel-infused, open cell, etc.) offer unique properties that can affect feel and performance.
- Layer configuration: Mattresses often use a combination of densities in different layers to provide a specific feel and support profile.
What are the benefits of a memory foam Density Chart?
Memory foam mattresses are popular because they are a great option for people who want to get a good night’s sleep. Some of the benefits of using memory foam include:
- They offer a soft and comfortable surface that is perfect for people who have back or hip pain.
- They allow you to move around without feeling stiff or contorted since the material is bouncy and conforms to your body shape while you sleep.
- Some brands now offer memory foam mattresses that have cool gel layers that are a great option for people who sweat and don’t want to smell bad the next morning.
- People often get respiratory benefits from sleeping on memory foam bedding if they suffer from asthma or sleep apnea, however, this is not possible with all types of mattress products when shopping online for pillows & sheets because different models will feature materials that help keep the mattress fresh.
Are there any risks associated with memory foam mattresses?
There are a few potential risks associated with using memory foam mattresses, but most of these risks can be mitigated by following some simple safety guidelines. Some of the risks that people may face when sleeping on a memory foam mattress include:
- Sleeping on one side of the bed for an extended period can cause pressure points on your spine and contribute to back pain.
- If you have any allergies or sensitivities, sleeping on a memory foam mattress can be unpleasant because there are different types of materials used in its production.
- It is very important for people with sensitive skin or who may suffer from asthma, allergies, and/or respiratory problems, never sleep directly on the material used in most memory foam mattresses as they could still increase your chances of developing health issues by breathing air trapped inside these products.
- Memory foams are naturally inflatable, so the material can expand and respond differently to body heat.
- Sleeping on one side for long periods contributes to this expansion especially if you do not have air conditioning or fans running during indoor warm months in areas where memory foam mattresses are manufactured.
- Depending on the type of edge used in a mattress that does use tongue & groove mechanisms, there is a potential risk of these products being cut through by bodily fluids (blood).
Which type of memory foam is best for me?
There is no one right answer to this question since everyone will have different needs and preferences when it comes to sleeping. But still, you can consider the type of sleep you usually enjoy.
If you are a light sleeper, for example, then a soft memory foam mattress may be more comfortable for you than one with harder layers. Not everyone’s choices are the same. So you can choose your desired one from the memory foam density chart.
