Why you should trust this review
We entered this review category with skepticism about whether cooling memory foam could genuinely deliver on its promises. Our testing protocol was specifically designed to identify whether the cooling improvements were real or superficial. We used a standardized 90-minute heat-soak test plus a full overnight test on each mattress to separate short-term from sustained cooling performance.
Memory foam pressure relief is our team’s specialty. We have tested over 40 foam mattresses in the past three years and have developed reliable benchmarks for what constitutes excellent, adequate, or poor pressure relief, which we apply alongside the temperature measurements in this review.
How we tested cooling memory foam mattresses
We measured surface temperature at 15, 30, 60, and 90 minutes in the heat-soak test with a 150-pound weighted form. This simulated the stillness of deep sleep, which is when heat buildup is most severe on foam surfaces. We then compared these readings to baseline temperatures on a standard non-cooling memory foam mattress tested at the same time.
For the full overnight test, we used wrist-worn temperature loggers to track skin temperature throughout the night and flagged moments when temperature exceeded 95 degrees Fahrenheit, which we defined as the discomfort threshold for our test group.
Who should buy a cooling memory foam mattress?
People who love the feel and pressure relief of memory foam but run hot are the clear audience. These are buyers who have tried switching to hybrid mattresses but found they missed the slow-contouring, motion-isolating feel of foam. A cooling memory foam mattress is the best compromise.
Light sleepers who are sensitive to motion transfer should also consider this category. Even the best cooling hybrid mattresses have more bounce and motion transfer than a well-made foam model.
Nectar Copper Mattress: best cooling memory foam overall
The Nectar Copper features a 3-inch layer of copper-gel infused memory foam over a 3-inch transition layer and a 6-inch high-density foam base. The copper infusion is consistent throughout the foam rather than just on the surface, which means the thermal conductivity benefit persists as the foam compresses under body weight.
In our heat-soak test, the surface temperature at 90 minutes was 2.4 degrees cooler than our standard memory foam baseline. In the overnight test, our testers reported fewer nighttime awakenings due to heat compared to their previous foam mattresses. Motion isolation was excellent, as expected from a foam construction.
At $799 for a queen with a 365-night trial and lifetime warranty, it offers a level of purchase confidence that matches the premium DTC brands at a more accessible price.
Amerisleep AS3: best cooling memory foam for pressure relief priority
The Amerisleep AS3 uses Bio-Pur foam, a plant-based open-cell memory foam that the brand claims is inherently more breathable than petroleum-based alternatives. In our testing the open-cell structure contributed to better airflow than standard gel-infused foam, though the improvement was modest compared to copper-infused alternatives.
Where it excels is pressure relief. Our testers rated it highest for shoulder and hip comfort, and the medium firmness makes it versatile across side and back sleeping positions. At $1,099 it is priced at the higher end of the all-foam category, but the 100-night trial and 20-year warranty justify the investment for buyers who know they prefer foam.
What to look for in a cooling memory foam mattress
Copper and open-cell foam construction are the two most effective cooling technologies for all-foam mattresses. Gel infusions are better than nothing but lose effectiveness faster under sustained body heat. Look for mattresses that specify the type and location of their cooling materials rather than general “cooling foam” claims.
Consider the base foam density. A high-density base (3 pounds per cubic foot or higher) resists heat absorption better than lower-density bases and also extends the lifespan of the mattress. A low-density base that softens quickly will also compact the comfort layer, reducing airflow over time.
Frequently asked questions
Does gel memory foam actually sleep cooler?+
Gel infusions help in the short term but lose effectiveness after 30 to 60 minutes of body contact. Open-cell foam structure has a more lasting cooling effect.
What is copper-infused memory foam?+
Copper particles are blended into the foam to improve thermal conductivity. Copper draws heat away from the body more effectively than gel beads and maintains this property over time.
Can a memory foam mattress ever be as cool as a hybrid?+
No all-foam mattress reaches the same cooling level as a well-designed hybrid with pocketed coils. However, the best cooling memory foam models close the gap significantly.
How long does memory foam take to off-gas?+
Most off-gassing dissipates within 24 to 72 hours in a ventilated room. Airing the mattress near an open window speeds up the process.
