What Is The Best Foam Mattress?

Discovering the ideal foam mattress involves considering a variety of factors, including the type of foam, density, firmness, sleeping position, and personal preferences. While it’s impossible to crown a one-size-fits-all champion, the memory foam mattress has gained widespread applause for its pressure-relieving abilities and customized support. Among the top contenders in the foam mattress category, the Tempur-Pedic brand often stands out for its high-quality, durable, and well-designed memory foam options. However, there are numerous other brands like Purple, Casper, and Leesa that have also carved out significant niches for themselves with innovative foam mattresses that suit diverse needs.

A Closer Look at Foam Mattress Types

Foam mattresses are revered for their pressure-relieving comfort, ability to contour to the body, and relative quietness when bearing weight. They come in various types, each offering unique benefits.

Memory Foam

Memory foam, also known as viscoelastic foam, is celebrated for its deep contouring properties. It responds to heat and pressure to mold to the body’s shape, providing personalized support. A downside, however, is that traditional memory foam tends to trap heat. To address this, many memory foam mattresses now incorporate gel infusions or open-cell technology to promote airflow and reduce heat retention.

Latex Foam

Latex foam is often derived from the sap of rubber trees and is known for its responsiveness, durability, and eco-friendly properties. There are two main types of latex used in mattresses: Dunlop, which is denser and heavier, and Talalay, which is lighter and has a more consistent texture. Latex mattresses tend to be bouncier than memory foam and do not offer the same level of motion isolation, but they are cooler and are often preferred by those looking for a more natural mattress option.

Polyurethane Foam (Polyfoam)

This is a less expensive foam that is widely used as a support layer in many mattresses. Polyfoam doesn’t conform to the body as closely as memory foam, but high-density versions can offer good support and durability. It’s more common to see polyfoam used in combination with other foams or as a transition layer in an innerspring mattress.

Foam Density and Firmness

When shopping for a foam mattress, you’ll encounter terms like density and firmness. These elements play a pivotal role in the longevity and comfort of a mattress.


Density refers to how much material is in the foam and is usually measured in pounds per cubic foot (PCF). High-density foams (over 5 PCF for memory foam) offer more durability and better body contouring, but can trap more heat. Medium-density foams (around 4 PCF for memory foam) strike a balance between durability and heat management. Low-density foams (less than 3 PCF) are less durable but are usually more affordable and offer less heat retention.


Firmness measures the initial feel of a mattress when you first lie on it. It’s a subjective measure, often rated on a scale from very soft to very firm. Side sleepers typically prefer a softer mattress that can cushion their hips and shoulders, while stomach and back sleepers may require a firmer surface to maintain spinal alignment. Your weight also affects the perceived firmness; heavier individuals may sink deeper into a mattress, finding a firm bed to feel softer and vice versa.

Considering Sleep Position and Body Type

Sleeping position and body type are critical factors in selecting the right foam mattress.

Side Sleepers

Side sleepers need a mattress that provides pressure relief at the shoulders and hips. A medium to medium-soft memory foam mattress is often ideal, as it allows for adequate contouring without causing misalignment.

Back Sleepers

Back sleepers require a balance of support and contouring to keep their spine aligned while supporting the natural curve of their lower back. A medium-firm to firm mattress usually works best.

Stomach Sleepers

Stomach sleepers need a firm mattress to prevent their hips from sinking too deeply, which can lead to back pain. A firmer base with a lighter comfort layer of foam can provide the necessary support.

Combination Sleepers

Those who sleep in multiple positions should look for a responsive foam mattress that facilitates easy movement and offers an adequate blend of support and pressure relief. A medium-firm mattress is often a suitable choice.

Body Type

Heavier individuals may prefer a thicker, high-density foam mattress that offers deep compression support. A firmer feel can also be advantageous to prevent excessive sinkage. Lighter individuals may favor a softer, less dense foam that provides sufficient comfort without feeling too firm.

Temperature Regulation and Cooling Features

One common complaint about foam mattresses is that they can sleep hot. However, innovations in foam technology have given rise to various cooling features designed to combat this issue.

Gel-Infused Foam

Gel-infused memory foam incorporates gel beads that are designed to wick away heat, helping to keep the mattress surface cooler.

Open-Cell and Plant-Based Foams

Open-cell foams have an internal structure that is more open, allowing for improved airflow. Plant-based foams replace some of the petrochemicals in traditional foam with plant-derived materials, often resulting in improved breathability.

Cover Materials

The cover of a foam mattress can also affect temperature regulation. Fabrics like bamboo, Tencel, and certain cotton blends are known for their moisture-wicking and cooling properties.

Edge Support and Motion Isolation

Foam mattresses excel in motion isolation, making them an excellent choice for couples, but edge support can sometimes be lacking in all-foam constructions.

Motion Isolation

Foam mattresses, especially those made with memory foam, are adept at absorbing movement. This means that when one partner moves during the night, the other is less likely to be disturbed.

Edge Support

Strong edge support is important for those who sit or sleep near the perimeter of the bed. Some foam mattresses reinforce the edges with denser foam or additional support layers to counteract the compression that can occur when weight is applied along the edges.

Understanding Off-Gassing

New Mattress Smell

Off-gassing refers to the release of volatile organic compounds (VOCs) from a new foam mattress. While not considered harmful, the odor can be unpleasant. This smell usually dissipates within a few days to a week with proper ventilation.

Durability and Warranty Considerations

Foam mattresses vary widely in their lifespan, depending on the quality of materials and construction.


High-quality, high-density foams tend to last longer than their lower-density counterparts. Latex foam is particularly known for its durability, often outlasting other foam types.


Always check the warranty on a foam mattress, as it can give you an idea of the expected lifespan and what type of sagging or indentations are covered.

Finishing Thoughts

Finding the best foam mattress ultimately boils down to personal preference shaped by your sleep style, body type, comfort preferences, and temperature sensibilities. Evaluate the type of foam, density, firmness, cooling features, and more while considering the role they play in your sleep quality. Memory foam mattresses, particularly those with cooling technologies and a balance between comfort and support, are a popular choice, but latex and polyfoam options may better suit certain individuals. Remember to also consider off-gassing, durability, and warranty as part of your decision-making process. A well-chosen foam mattress can greatly improve your sleep quality and, in turn, your overall health and well-being.
