    Our coolest mattress ever

    Keep your cool all year long with the Polar+ Mattress. Our PolarBands™ are designed to dissipate body heat, keeping you cooler even through the hot summer months. It’s the cool change you’ve been waiting for.

    Sleep 5°C cooler

    The Polar+ sleeps 5°C cooler than the Plus*, thanks to innovative PolarBands™ embedded in the topper that act as thermal highways to absorb and release body heat for 8+ hours. Combined with moisture-wicking CoolThread™ fabric, cooling gel Kloudcell® foam, and a seasonal adjustment layer, it’s the perfect mattress for hot sleepers and warm summer nights.

    +60% Kloudcell® equals more comfort

    Imagine sleeping on a really chill, comfortable, cool cloud. This is as close as you’ll get. The Koala Polar+ Mattress boasts 60% more Kloudcell® compared to the SE Mattress.

    Australian climate-ready

    Our quilted topper is ready to tackle every season. You can simply unzip and flip it over to take you from comfy organic cotton when it’s chilly, to crisp CoolThread™ when it’s hot.

    Choose your own comfort

    The Koala Polar+ Mattress also features our trademark double-sided Kloudcell® comfort layer, which gives you the choice between medium-firm and firm comfort. Simply unzip and flip the comfort layer to find your sweet spot.

      Koala mattress and pillows

      Lovely and comfortable. Nice to have choice between firm and medium firm. Because we live in the subtropics it's great the topper has a summer and winter option.

      we now sleep through the night without disturbing one another

      We Love our new mattress. Last week I asked hubby if he noticed how restlessly I slept (food induced wise) and he said no. previously if I had a bad night he would as well. movement used to be felt all over our old mattress. Now I can get up early and go for a walk without waking my husband. my back also appreciates the firmness while still feeling like I am in a soft bed. I wish we had changed over earlier.

    Frequently asked questions

    What are PolarBands™?

    PolarBands™ are an innovative cooling technology that are designed to remove excess body heat in order to achieve a naturally comfortable temperature. Highly thermally conductive PolarBands™ are embedded in the top layer of your Polar+ Mattress, around the centre of the body, in order to conduct heat away from the places where it usually accumulates.

    Do you sell the Polar+ topper on its own?

    No, the Polar+ topper is not available to purchase separately.

    How do I change the seasonal topper?

    To change from the winter side to the summer side, unzip and flip the topper. Align the zipper ends and fully close the zipper.

    How do I change the firmness?

    To change the firmness, unzip the seasonal topper, and flip the comfort layer over to your preference. Check that the firmness label has your preferred comfort level facing upwards. Replace the seasonal topper, align the zipper ends and fully close the zipper on the topper.

    I've just bought a new mattress, which side of the comfort layer should I try first?

    Congratulations on purchasing your very own Koala mattress from Australia's most awarded mattress range! We recommend trying out the medium-firm side first to get a feel for the mattress and see how it interacts with your body. If after a few nights you're finding it a bit too soft, you can simply unzip the topper, flip over the comfort layer, and zip it back up for a firmer feel.

    What is CoolThread™ fabric?

    CoolThread™ is a special blend of cooling yarn, designed to feel instantly cool against the skin, and wick away moisture to help you stay cool throughout the night.

    Can I wash the seasonal topper? Can I dry clean the seasonal topper?

    To help keep your seasonal topper looking its best, we recommend you follow the care instructions, and wipe clean with a damp cloth. Unfortunately washing or dry cleaning the topper will damage the Kloudcell® foam, and may void your warranty.

    Do I need to use a mattress protector?

    We recommend you use a mattress protector to keep your Koala Polar+ looking its best. As the CoolThread™ fabric will have the maximum cooling effect when it's closer to your skin, we suggest you try a lightweight protector like the Great Barrier Mattress Protector.

    *Koala R&D testing found the Koala Polar+ Mattress achieves a surface temperature 5°C cooler than the Koala Plus Mattress over 8 hours.
