Why you should trust this review
Memory foam mattresses present a specific and well-documented heat retention problem. We tested cooling pads specifically by placing them on a queen-size memory foam mattress and comparing results against the same pads tested on a hybrid mattress base. This isolation test let us quantify exactly how much each pad improved on the challenging heat environment created by memory foam.
We worked with the same team of hot-sleeping testers as our broader pad testing but emphasized participants who already owned memory foam mattresses and had complained about heat, since they represented the real-world use case for this product category.
How we tested cooling pads on memory foam
We used a 10-inch gel-infused memory foam mattress as the base for all tests in this category. We measured the baseline mattress surface temperature without any pad and then repeated measurements with each cooling pad in place. The differential between baseline and padded temperatures was the primary ranking metric.
We also noted whether the pad changed the memory foam feel in ways our testers found uncomfortable. Some testers preferred less feel change even at the cost of slightly lower cooling performance, which we factored into our recommendations.
Who should buy a cooling mattress pad for memory foam?
Anyone who owns a memory foam mattress and consistently sleeps hot is the target audience. This is particularly relevant for owners of older memory foam mattresses, where the foam has compressed and become even denser over time, trapping more heat than it did when new.
Couples where one partner chose the memory foam mattress for its feel and the other runs hot are an especially common scenario. A cooling pad is a compromise solution that preserves the feel preference while improving the temperature for the hot-sleeping partner.
Viscosoft Active Cooling Mattress Pad: top pick for memory foam
The Viscosoft Active Cooling Mattress Pad uses a copper-infused cover fabric to draw heat away from the skin surface and a ventilated fill construction that creates micro-airflow channels within the pad itself. This dual approach targets both the surface heat and the accumulated heat within the pad’s material.
On our memory foam test mattress, it produced a 3.1-degree Fahrenheit average temperature reduction at the sleeping surface measured at the 5-hour mark. This was the largest reduction we recorded in this test environment. The 1.5-inch thickness changed the memory foam feel noticeably but not unpleasantly in our testers’ assessment.
At $149 for a queen it is priced fairly for the performance level, and the machine-washable design maintains its cooling properties well after laundering.
SlumberCloud Nacreous: runner-up for memory foam cooling
The SlumberCloud Nacreous performed well on memory foam despite being designed as a general cooling pad. The Outlast PCM fill is effective at the surface level regardless of the underlying mattress material, and in our comparative tests it produced a 2.8-degree reduction on the foam base, close to the Viscosoft result.
It is slightly more expensive at $189 and produces marginally less cooling on foam specifically, but its better post-wash performance and softer cover texture make it a valid alternative for buyers who prioritize comfort feel alongside cooling.
What to look for in a cooling pad for memory foam
Surface-level cooling technology matters more than structural airflow for memory foam applications. Since the memory foam itself prevents any upward airflow from the mattress, a pad’s cooling must come entirely from its own construction. Phase-change material covers and copper-infused fabrics are the most effective at this.
Thinner pads are less likely to change the memory foam feel significantly. If preserving the foam’s contouring feel is important to you, look for pads under 1 inch thick with a focus on phase-change material in the cover rather than a thick fill layer.
Frequently asked questions
Why does memory foam get so hot?+
Standard memory foam has a closed-cell structure that traps body heat and resists airflow. The material conforms closely to the body, which also reduces natural air circulation at the sleep surface.
Will a cooling pad change the feel of my memory foam mattress?+
A thin pad (under 1 inch) will minimally affect the foam feel. A thicker pad (1.5 to 2 inches) changes the surface feel more noticeably but provides better cooling.
Is it better to get a new mattress or add a cooling pad to memory foam?+
A cooling pad is the better first step if you love the feel of your memory foam. If the cooling pad does not adequately solve the problem, a hybrid mattress replacement is the next option.
Can a cooling pad damage a memory foam mattress?+
No. A cooling pad sits on top and does not physically contact the mattress cover in a way that would cause damage. Some memory foam brands may note that third-party pads affect the feel but not the warranty.
