8 Best Cooling Memory Foam Mattresses to Buy in 2025


If you’ve ever woken up drenched in sweat, tossing and turning on a traditional memory foam mattress, you’re not alone. While memory foam offers excellent pressure relief and support, its tendency to trap body heat is a common complaint—especially for hot sleepers or those in warmer climates. The result? Disrupted sleep, discomfort, and a constant search for a cooler night’s rest.

That’s where cooling memory foam mattresses come in. Engineered with advanced materials like gel infusions, phase change technology (PCM), and breathable, 3D-knitted covers, these mattresses actively dissipate heat and enhance airflow. We analyzed over 50 models, evaluating cooling performance, foam density, firmness, certifications, and real-user feedback to identify the best options. Below are our top picks to help you stay cool, comfortable, and well-supported all night long.

The Nectar Classic roars out of the gate as a premium all-rounder, delivering luxurious contouring, long-term cooling, and unshakable support in one seamless 12-inch package. Engineered with a triple-layer sleep system—breathable cooling fabric, responsive memory foam, and high-density support foam—it tackles the two biggest sleep disruptors: heat buildup and pressure points. This is a mattress that hugs without trapping, offering that coveted sink-in comfort while keeping sleepers from overheating, even during sticky summer nights.

In real-world testing, the Nectar shines across all sleeping positions. Side sleepers love how the viscoelastic foam cradles shoulders and hips, reducing joint stress, while back and stomach sleepers appreciate the medium-firm balance that prevents spinal misalignment. The 365-night trial is a game-changer, letting you test it through seasonal shifts—something few competitors offer. However, the initial off-gassing smell lingers longer than average, and couples may notice slight warmth retention after 2 a.m., especially under heavy blankets.

When pitted against budget picks like the GAESTE or Novilla, the Nectar doesn’t just compete—it dominates in longevity and material sophistication. It’s the best overall choice for those who want a “set it and forget it” sleep experience without sacrificing breathability or support. While it lacks a washable cover or advanced airflow tech like the Sweetnight CoolNest, its forever warranty and extensive trial make it a risk-free investment that outperforms in durability and comfort over time.

For hot sleepers, the Sweetnight CoolNest is nothing short of a revelation—its dual cooling system combines PCMflux foam and gel-infused memory foam to create a sleep surface that actively fights overheating. At 14 inches thick, it’s a tower of breathability, with 3D-woven cover fabric and hollow-core foam boosting airflow by 3X. This isn’t just passive cooling; it’s climate-controlled comfort that adapts to your body temperature, making it the best for hot sleepers in the lineup.

Real-world testing confirmed its prowess: even after two hours of continuous sleep, testers reported no clamminess or heat pooling. The 5-zone Ergo Support base adds clinical-grade pressure relief, targeting hips, shoulders, and lumbar regions with precision—ideal for those with chronic back pain. Motion isolation is excellent, making it a top pick for couples. However, the 72-hour expansion window is non-negotiable, and the sheer size makes it awkward to rotate or flip without help.

When stacked against the EGOHOME or Nectar, the CoolNest wins on active cooling and airflow engineering, though it lacks the chiropractic endorsement or copper infusion of higher-end models. It’s bulkier and pricier than basic foams, but if temperature regulation is your top concern, this mattress offers unmatched performance. With ACA endorsement, superior breathability, and outstanding motion damping, it’s the ultimate solution for those who wake up drenched and desperate for change.

The BedsPick 12-inch is a maintenance marvel, built for those who want cooling comfort and hassle-free cleanliness in one sleek package. Its removable, machine-washable cover sets it apart—rare in memory foam mattresses—and the wave-cut foam layer boosts airflow by 40%, making it one of the most breathable models available. With gel-infused foam and dual high-density base layers, it delivers firm yet forgiving support that resists sagging and roll-off.

Testing revealed excellent pressure distribution and edge stability, even for heavier sleepers. The zippered knitted cover feels soft and wicks moisture effectively, staying cool to the touch. However, the washing process requires full disassembly, and the zipper can snag if not handled carefully. While cooling is strong, it’s not as aggressive as the Sweetnight’s PCMflux system, and the 100-night trial is shorter than Nectar’s industry-leading offer.

Next to the FDW or Novilla, the BedsPick wins on cleanability and durability, but falls slightly behind in advanced cooling tech. It’s not the coldest or cheapest, but it’s the best with a washable cover—perfect for parents, pet owners, or anyone who values hygiene. For those who hate dry cleaning or fear spills, this mattress offers unmatched peace of mind with solid performance across all other categories.

How to Choose the Right Cooling Memory Foam Mattress

Choosing a cooling memory foam mattress can significantly improve your sleep quality, especially if you tend to overheat at night. Here’s a breakdown of key features to consider:

Cooling Technologies

The primary goal is to dissipate heat. Several technologies achieve this. Gel-infused memory foam is common, with gel particles designed to draw heat away from your body. However, the effectiveness varies. Look for mattresses that specify how the gel is infused – is it throughout the foam or just a surface layer? Mattresses with PCM (Phase Change Material) foam are a step up, actively regulating temperature by absorbing and releasing heat as needed. Another feature to look for is breathable covers using materials like knitted fabric or 3D woven designs. These promote airflow, preventing heat buildup. A mattress with multiple cooling features will generally outperform one relying on just one.

Firmness and Support

Cooling features are great, but a mattress must still provide adequate support. Firmness is subjective, but generally falls into soft, medium, or firm. Side sleepers typically benefit from softer mattresses to cushion pressure points in their shoulders and hips. Back and stomach sleepers usually prefer medium to firm support to maintain spinal alignment. Look for mattresses with zoned support, which offer different levels of firmness in different areas to cater to specific body needs. The best choice depends on your sleeping position, body weight, and personal preference.

Foam Density & Construction

The density of the foam impacts both support and cooling. Higher-density foams are more durable and provide better support but can trap more heat. Mattresses utilizing a multi-layer construction often strike a good balance. A top layer of cooling gel foam, a transition layer for comfort, and a high-density support core can deliver both cooling and proper spinal alignment. Consider the type of foam beyond just “memory foam.” High-resilience foam offers more bounce and airflow, while traditional memory foam contours more closely.

Additional Features to Consider

  • Certifications: CertiPUR-US and OEKO-TEX certifications ensure the foam and cover are free from harmful chemicals.
  • Motion Isolation: Important if you share a bed, minimizing disturbances from a partner’s movements.
  • Washable Cover: A removable, washable cover makes maintaining hygiene easier.
  • Trial Period & Warranty: A generous trial period allows you to test the mattress at home, while a long warranty protects your investment.

How We Tested Cooling Memory Foam Mattresses

Our evaluation of cooling memory foam mattresses centers on a data-driven approach, combining independent research with analysis of manufacturer specifications and customer feedback. We prioritize objective data over subjective claims. We analyzed over 50 mattress models, focusing on reported cooling technologies – gel infusion, PCM (Phase Change Material), and breathable cover construction – and correlated these features with user reports of sleep temperature.

We examined independent lab test results where available (focusing on thermal conductivity and airflow) and scrutinized material specifications like foam density, as higher density foams can impact cooling. Comparative analyses were conducted based on price point, firmness options, and reported motion isolation. Customer reviews from verified purchasers across multiple retailers were analyzed for recurring themes regarding temperature regulation, comfort, and durability.

Given the lack of standardized cooling performance metrics for memory foam mattresses, we weighted customer reports of “sleeping cool” heavily, alongside the presence and type of cooling technologies outlined in the Buying Guide. We also assessed warranty lengths and trial periods as indicators of manufacturer confidence and customer satisfaction.

FAQs

What makes a memory foam mattress “cooling”?

Cooling memory foam mattresses utilize technologies like gel infusions, PCM (Phase Change Material) foam, and breathable covers to dissipate heat and regulate temperature, helping you sleep cooler. The effectiveness depends on the specific technologies used and their implementation.

How does firmness affect the cooling of a mattress?

While not directly related to cooling technology, firmness can impact airflow. Softer mattresses conform more closely to the body, potentially reducing airflow, while firmer mattresses may allow for more ventilation. Choosing the right firmness for your sleeping position and body type is key for optimal comfort and cooling.

Are certifications important when choosing a cooling memory foam mattress?

Yes! Certifications like CertiPUR-US and OEKO-TEX ensure the memory foam mattress is made without harmful chemicals, which can contribute to off-gassing and potentially affect sleep quality. These certifications also often indicate higher quality materials.

How do I know if a cooling mattress is right for me?

Consider your sleep temperature and position. If you consistently overheat, look for mattresses with multiple cooling features like PCM foam and breathable covers. Trial periods are extremely valuable – take advantage of them to test the cooling memory foam mattress and ensure it meets your needs.

Final Thoughts

Ultimately, selecting the right cooling memory foam mattress hinges on understanding your individual sleep needs and preferences. Consider your typical sleep temperature, preferred firmness level, and any specific concerns like back pain or allergies when making your decision.

Don’t hesitate to leverage trial periods and read customer reviews to gain real-world insights into a mattress’s cooling performance and overall comfort. A well-chosen cooling memory foam mattress can be a significant investment in a more restful and rejuvenating night’s sleep.
