Open-cell foam is created with small cells that are not fully closed. The spaces created inside the cells are occupied by air so that open-cell memory foam mattresses are less dense and have a softer feel compared to the closed-cell option. As the air is allowed to fill in the interior of the foam and can move freely through the structure, a memory foam mattress with an open-cell construction will feel cooler than a closed-cell memory foam mattress. This is because excess heat is not allowed to build up inside the foam and is instead dissipated outwards before it can cause discomfort to the sleeper.

Pros

Breathable

The open-celled structure of this type of memory foam results in enhanced breathability compared to a closed-cell construction. As air is allowed to flow freely throughout the foam, the sleeping surface remains cool and comfortable as it prevents the accumulation of excess body heat. This improved breathability is especially beneficial to people who tend to feel extreme warmth when staying in the same sleeping position for the duration of a night. Instead of tossing and turning to avoid a hot spot on the mattress, the sleeper can instead enjoy uninterrupted sleep as the surface maintains a comfortable temperature for long hours.

Reduced Off-Gassing

Off-gassing refers to the release of bothersome smells into the air and is often experienced when using foam mattresses that have been manufactured using harsh chemicals. Open-cell memory foam mattresses do not contain volatile organic compounds or gases that can be released into (and harm) the environment. These mattresses can be used from the time they’re delivered to your home without the need to endure a few days of strong odors. With the reduced off-gassing, the air quality in your bedroom can be preserved and you can enjoy the features of the high-quality mattress without strange smells around you.

Durable

Open-cell memory foam is strong and durable so you can depend on the structure to last for a long time. This construction will not easily shrink or deteriorate even with heavy or regular use. This means you’ll be able to fully take advantage of the premium qualities of the mattress for years to come. The aesthetics of the mattress will also be maintained for a long time with the material’s durable nature.

Softer Profile

Those who prefer a softer mattress will benefit from the less dense structure of an open-cell memory foam mattress. The memory foam provides a more cushioned sensation compared to a closed-cell foam that has a rigid construction, resulting in a mattress that will more easily follow the shape of your body. The foam will allow your body to slightly sink in to prevent pressure spots from forming while ensuring that the surface is still comfortable enough to encourage you to fall asleep quickly.

More Affordable

An open-cell memory foam mattress is generally priced lower compared to a closed-cell option because open-celled memory foam requires fewer materials for its production. A memory foam mattress constructed using open-cell technology will be an ideal choice for budget-conscious shoppers who want a lower-priced mattress that can still deliver premium benefits.

Cons

Reduced Density

Open-cell memory foam has a lower density compared to closed-cell construction, which usually translates to decreased durability and strength. However, technology has allowed mattress brands to create open-cell memory foam mattresses that offer superior strength and durability so there will be no worries about the mattress’ ability to withstand heavy use and abuse for a long time.
