What is Foam? Facts (Pros & Cons)

A foam mattress, widely recognized for its comfort and pressure-relieving properties, has emerged as a popular choice for sleep enthusiasts. The technology involves using foam as the primary material in a mattress, which contours to the body's shape. Let's dive into the world of foam mattresses and explore their pros, cons, and key considerations.

The Intriguing World of Foam Mattresses

The Definition: What Is A Foam Mattress?

A foam mattress is a type of bedding that uses foam - a cellular, solid material that deforms under pressure - in its construction. The most common type is memory foam, known for its unique ability to contour to the body for personalized comfort. There are also latex foam mattresses, and mattresses that combine different types of foam for a balanced feel.

Why Choose A Foam Mattress?

Foam mattresses are often chosen for their unique combination of comfort and support. They excel in pressure relief, conforming to the body to distribute weight evenly and alleviate stress on pressure points. They are also relatively quiet and absorb motion, making them an excellent choice for those who share a bed.

Advantages of Foam Mattresses

Superior Comfort and Pressure Relief

Foam mattresses conform to the body's shape, providing excellent pressure relief. They can help reduce aches and pains by providing cushioning to pressure points like hips and shoulders.

Motion Isolation

Memory foam mattresses, in particular, are excellent at isolating motion, which means movement on one side of the bed is unlikely to disturb someone sleeping on the other side.


Foam mattresses, especially those made of memory foam, are usually dense enough to prevent dust mites and other allergens from settling into the mattress.

Potential Drawbacks of Foam Mattresses

Heat Retention

One common complaint about foam mattresses is that they can trap heat, making them less comfortable for hot sleepers. However, many modern foam mattresses incorporate cooling technologies to mitigate this issue.


New foam mattresses often emit a chemical smell known as off-gassing. While this usually dissipates within a few days, it can be a nuisance for some people.

Edge Support

Traditional foam mattresses might lack robust edge support. When sitting on the edge of the bed, you might feel a significant sinkage. This can be a drawback for those who prefer sitting on the edge or sleeping near it.

The Verdict: Is A Foam Mattress Right For You?

The choice to opt for a foam mattress will depend on personal preferences and sleep needs. If you value comfort, pressure relief, and motion isolation, a foam mattress could be the perfect fit for you. However, if you're a hot sleeper or bothered by off-gassing, you may want to explore options with cooling technology or look for CertiPUR-US® certified foams, which have lower VOC emissions.

In the grand scheme of things, a foam mattress offers a unique blend of comfort and support. The key is to consider its pros and cons, do some research, and perhaps try out a few models to find the perfect one for your dreamy slumber.
