Occasionally, we hear from customers who are concerned about the stories they’ve heard about hot memory foam mattresses. In most of these situations, a friend or acquaintance has complained about how hot their memory foam mattress is, and how it’s difficult to sleep and stay cool & dry. Chances are, this person has inadvertently purchased a memory foam mattress made of low-quality, slow recovery memory foam designed with a closed cell design.
Open Cell vs. Closed Cell Memory Foam
Memory foam is designed with either an open cell or closed cell make up. Open cell memory foam returns to it’s previous shape quickly, and allows for more airflow through the material. Think of open cell memory foam as having tiny air balloons in its core. Even with pressure applied to the foam, air is able to flow through the memory foam mattress. This keeps the mattress cool, fresh, and dry.
Closed memory foam is designed for many uses, and some lower-quality manufacturers may use closed cell memory foam for mattresses. These mattresses do not allow for adequate air flow, which will lead to a warm sleeping surface. The memory foam is unable to “breathe,” which traps moisture & body heat, making sleep less sound.
Rocky Mountain Mattress Products
The manufacturers used by Rocky Mountain Mattress – Bayer & Foamex memory foam mattresses – use only open-cell mattresses. These products are specifically designed to be breathable, cool, and dry, and are among the highest quality foams created.
In fact, the Aerus by Foamex is a revolutionary memory foam which allows air to flow up to eight times more freely through its open cell system.
As the air travels through the memory foam, heat and moisture is pulled away from the sleeping individual and out of the memory foam mattress.
