Best Cooling Mattresses 2025
Let's have some straight talk: 90% of "cooling" mattresses are just marketing gimmicks. A thin layer of gel foam isn't going to stop night sweats.
To actually sleep cooler, you need physics—materials that physically conduct heat away from your body (Phase Change Material), or materials that allow massive airflow (Latex and Hybrids). Below are the three best mattresses I have tested that actually keep the temperature down.
Top 3 Cooling Picks
Black Diamond Mattress
This is heavy-duty cooling tech. It uses "Ice Flex" bands that are physically cool to the touch and conductive Cool Titanium memory foam to pull heat away from your core for 12+ hours.
- Ice Flex: Mineral-based cooling bands.
- Titanium Foam: Highly conductive memory foam.
- CoolTouch Cover: Instantly cold feel.
Helix Elite Series
At 16 inches tall, this is a beast. The secret weapon here is the Cool Force Layer—a dedicated layer of graphite ribbons designed specifically to absorb excess body heat.
- Cool Force: Graphite ribbons absorb heat.
- GlacioTex Cover: Slick, cooling surface.
- Micro-Coils: Two layers for max airflow.
Yawnder Mattress
If you hate the chemical feel of cooling gels, go natural. We use Tencel and Talalay Latex. Latex has an open-cell structure that breathes naturally, preventing heat buildup in the first place.
- Natural Latex: Open-cell airflow.
- Tencel Cover: Superior moisture wicking.
- Joma Wool: Regulates temperature naturally.
Why Most "Cooling" Mattresses Fail
The industry loves to spray a little "cooling gel" into a dense block of foam and call it a day. That works for about 15 minutes. Once that foam heats up to your body temperature, it acts like insulation, trapping the heat against you.
The Solution? Conduction and Airflow. You need materials like the Phase Change Material (PCM) found in the Black Diamond and Helix Elite, which chemically change state to absorb heat. Or, you need the massive airflow of the Natural Latex in the Yawnder mattress, which simply refuses to hold onto heat.
Frequently Asked Questions
Do cooling mattresses actually work?
Yes, but only the high-quality ones. Cheap "cooling foam" saturates quickly. Look for Phase Change Material (PCM), Graphite infusion, or naturally breathable Latex to see real results.
Is latex cooler than memory foam?
Almost always. Latex is "open cell," meaning air flows through it like a sponge. Memory foam is "closed cell," meaning it traps air (and heat) to contour to your body.
What bedding should I use with a cooling mattress?
Don't ruin a $2,000 cooling mattress with $20 polyester sheets. Use Percale Cotton, Tencel, or Bamboo sheets (like the ones in my Sheet Review section) to let the mattress breathe.
