The Best Cooling Mattresses Have These Features

Shopping for the best cooling mattresses can feel like navigating a maze of marketing jargon and fancy-sounding tech. But here's the thing. Not all "cooling" features actually keep you cool. Some are just hot air (literally).

So, before you get swept up in the hype, let's break down cooling mattress features that actually work.

Advanced Mattress Materials

Not all mattress materials are created equal when it comes to keeping you cool. Some trap heat like a stuffy summer tent, while others let air flow freely like a coastal breeze. Here's what separates the cool customers from the heat trappers.

• Open-Cell Foam Technology: Traditional memory foam mattresses might hug you tight, but they also hug your heat and won't let go. Open-cell foams have interconnected air pockets that create tiny highways for heat to escape. Our Kloudcell® technology takes this concept and runs with it, creating a foam with breathability and support that traditional memory foam mattresses can’t match.

• Cooling Gel Technology: Gel memory foams have tiny gel particles acting like little heat sinks that absorb and disperse warmth away from your body. Cooling gel technology goes one step further. In mattresses such as our Koala Plus, Cooling Gel Kloudcell® actively draws heat away from your body, helping you sleep 13% cooler than other leading online brands, including those with traditional gel-infused memory foams.

• Phase-Change Materials: Phase-change materials are like having a personal thermostat built into your mattress. When you start heating up, these materials absorb the excess heat. When you cool down, they release it back. It's temperature regulation on autopilot. Our Koala Luxe Mattress features this cutting-edge tech integrated directly into the Kloudcell® topper.

• Copper Infusion: This naturally antimicrobial metal is a bloody brilliant heat conductor, which means it pulls heat away from your body faster than you can say "sweaty sleeper." When copper is infused into foam layers, it creates a network of tiny heat highways that whisk away warmth before it has a chance to build up. Plus, it naturally fights off bacteria and odours. Talk about a win-win.

Construction and Design Elements

While fancy cooling mattress materials get all the glory, it's actually the clever construction and thoughtful design elements that separate the sleep-saviours from the sweat-inducing disasters.

• Zoned Support: Not all parts of your body generate heat equally, and smart mattress design recognises this. Zoned support systems strategically place different materials and construction techniques where your body needs them most. These zones don’t just help with body temperature regulation. They also provide customised support for different pressure points.

• Breathable Cover Fabrics: The cover of your mattress is like the first checkpoint for heat management. Natural fibres like bamboo and TENCEL™ are absolute legends when it comes to moisture-wicking and breathability. TENCEL™, made from sustainably sourced wood, is particularly brilliant because it naturally pulls moisture away from your skin and releases it into the air.

• Edge Support: Proper edge support doesn't just prevent that annoying roll-off feeling. It also maintains the mattress's structural integrity, ensuring those internal Kloudcell® air channels stay open and functional. When your mattress has the right edge support, the entire cooling system works as designed.

Your Path to Advanced Cooling Technology and Better Sleep

Here's the thing about finding the right cooling mattress online: it actually works with all your other sleep tricks—the breathable sheets, the optimised room temperature, the pre-sleep cooling routine. But at the end of the day, if your mattress is trapping heat like a furnace, all those other efforts are fighting an uphill battle.

Your journey to cooler, more comfortable sleep starts with a new cooling mattress. Make your decision count, and make it tonight. Explore Koala's complete mattress lineup and discover which cooling solution will transform your sleep. No tools, no worries, just better nights ahead.
