If you constantly wake up feeling hot during the night, you’re not alone. Traditional memory foam mattresses often retain body heat, making it difficult to sleep comfortably. The CoolNest® Memory Foam Mattress was designed to address that problem with multiple cooling technologies that work together to create a cooler, more supportive sleeping environment.

After taking a closer look at its features, here’s what makes this mattress stand out.
What Is the CoolNest® Memory Foam Mattress?
The CoolNest® Memory Foam Mattress combines cooling materials, breathable construction, and ergonomic support into one mattress designed for all-night comfort.
Available in 12-inch, 14-inch, and 16-inch models, it offers multiple thickness options to suit different sleep preferences while maintaining the same advanced cooling technology throughout the collection.
Unlike many memory foam mattresses that trap heat, the CoolNest® uses several specialized layers to help regulate temperature and improve airflow. Find out more.
Cooling Technology Designed for Hot Sleepers
One of the biggest reasons shoppers consider the CoolNest® Mattress is its impressive cooling system.
3D Knitted Cooling Cover
The mattress begins with a soft 3D knitted cooling cover featuring more than 10,000 micro-ventilation holes. This breathable fabric encourages airflow while helping moisture evaporate quickly, leaving the surface feeling cooler throughout the night.
PCMflux® High Resilience Foam
Directly beneath the cover is PCMflux® High Resilience Foam.
This innovative layer uses phase-change materials (PCM) that absorb excess body heat when you’re warm and release it as temperatures change. The result is a more consistent sleeping temperature without the overheating common in traditional memory foam.
Gel-Infused Memory Foam
The next layer is gel-infused memory foam designed to provide pressure relief while helping dissipate heat. The cooling gel particles help prevent heat from building up deep within the mattress so you stay comfortable longer.

Breathable Construction Improves Airflow
Cooling isn’t limited to the top layers.
The CoolNest® features an innovative multi-layer airflow system with:
- Hollow foam construction
- Multiple breathable foam layers
- Hundreds of ventilation channels
- Airflow-enhancing perforations
Together, these features continuously circulate air throughout the mattress, reducing trapped heat and humidity while promoting a fresher sleeping environment.

5-Zone Ergonomic Support for Better Sleep
Comfort is only part of the equation. Proper spinal support is just as important.
The CoolNest® uses a 5-Zone Ergo Support System that provides targeted support for:
- Head and neck
- Shoulders
- Lower back
- Hips
- Legs and feet
Each section is engineered to cushion pressure points while encouraging healthy spinal alignment throughout the night.
Whether you sleep on your side, back, or switch positions, the zoned design adapts to your body for balanced support which allows you to sleep better.
High-Density Foam Base Provides Long-Term Durability
Supporting the comfort layers is a durable high-density foam base that helps prevent sagging over time.
This sturdy foundation improves stability while allowing the upper comfort layers to perform as intended night after night.
Motion Isolation Helps Couples Sleep Better
If you share your bed, motion transfer can be a major issue.
The memory foam construction absorbs movement instead of transferring it across the mattress. That means one person’s tossing, turning, or getting out of bed is less likely to disturb the other sleeper.
Quality Certifications
The CoolNest® Memory Foam Mattress includes several respected certifications that reflect its commitment to quality materials and construction.
These include:
- CertiPUR-US® Certified Foam
- OEKO-TEX® Certification
- ISPA Certification
- American Chiropractic Association (ACA) Certification for its ergonomic spinal support design
These certifications provide added confidence that the mattress has been tested for quality, safety, and performance.
