The Foams in Your Mattress

A foam mattress offers a soft and cushy surface ideal for sleeping on - but have you ever wondered what type of foam is really inside? After all “foam” is a broad term with a variety of different specifications.

So, let’s take a closer look at the types of foam that you will find in most common brands of mattress, so that you can make a well informed decision when you are buying a mattress.

Types of Foam

● Polyurethane Foam: This type of foam is very soft and seems to “melt” when you lay down on it. There are three grades of firmness with this type of foam, so keep the density in mind when you are shopping. Poly foam is an inexpensive option, but it can sometimes have issues with excessive offgassing (chemical smell) and lack of support. It can also adapt to your body impression over time.

● Memory Foam: Similar to polyfoam, it uses the same processes and materials. However, it has an increased density and viscosity. It gets the name “memory foam’ because when you lie on it it conforms to the shape of your body and then when you wake up it springs back to its original shape.

● Gel Memory Foam: This is a modern type of memory foam that is infused with gel. It was invented because traditional memory foam had some issues with holding onto too much heat. The gel that is swirled throughout the foam helps to keep you cool.

● Reflex Foam: This is a high density style of foam that has a medium level of firmness. It contains bubbles within, which move and conform to your body. However, when you get off the mattress the bubbles will bounce back to their original form - which is why it is known as reflex foam.

● Latex Rubber Foam: This type of foam is created using a white sap that comes from trees - which means that it is a renewable resource and an all natural product. It is very durable - a latex foam mattress can last up to 15 years. However, this is one of the more expensive mattress foam materials.

● Convoluted Foam: You might know it as “egg carton foam.” This is the type of coam that is made with peaks and valleys on the surface which resemble an egg carton. This foam is usually used in mattress toppers in order to add another level of support for sleepers. It is advantageous because it distributes heat and weight well and can provide you with good spinal alignment.

What's Important in a Foam?

What you deem important in a foam depends on what you are prioritizing when shopping for a bed. For example, if you have back and neck pain or sore joints, the cradling and support properties of memory foam can be very important. However, these types of foams can be less desirable for older consumers with mobility issues as they can make it more difficult to get out of bed.

Perhaps off-gassing is a problem for you and you are concerned with buying a mattress that will be releasing chemicals into your home? If this is the case, you will want to look for plant-based foam that is made with all natural ingredients and no harmful chemicals.

What Affects The Durability of a Foam?

One of the factors that will affect the durability of the foam is the density. Forms that are in the 2.5-3.5lb range will usually have less resilience and will show wear sooner than other foams. Foams that have a density of 4-5.5lbs will last a long longer before showing signs of wear.

Generally, the manufacturing origin will also tell you about the durability of the foam. Materials that are made in the USA are likely to last longer because they are subject to more stringent manufacturing guidelines.

Of course, it is important to find the right balance between longevity and comfort. A mattress might last a long time, but not be as comfortable. The goal is to find a balance that works for your preferences and your budget.

What About the Feel of the Foam?

If you like the feeling of sinking into your mattress and being cradled by a very soft surface, you’ll love memory foam. However, some people hate this sensation and report that it makes them feel like they are lying in quicksand. Also, many people have complained that very soft foam makes it difficult to have sex because your limbs sink into the material. If you prefer a firmer surface, you will enjoy reflex foam much more.

There are many different foams to choose from - so when you are shopping for a mattress it may be helpful to make a list of the factors that you desire in the foam. The more you know what you are looking for, the easier it will be to find the perfect foam bed for your needs.
