    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.

    The ultimate relief for hot sleepers

    PolarBands™ actively absorb and release body heat for 8+ hours. Paired with CoolThread™ and cooling Kloudcell, it's perfect for hot sleepers.

    Deep, cloud-like comfort

    With 60% more Kloudcell® foam than the SE Mattress, this layer offers a cushioned feel. It relieves pressure without losing stable support.

    Ready for any Australian season

    Your quilted topper has two sides built-in. Easily switch between soft organic cotton when it’s cold, or crisp CoolThread™ when you need cooling relief.

    Your perfect support, chosen at home

    The double-sided Kloudcell® comfort layer offers two feels: medium-firm or firm. Easily unzip and flip the layer to find your sweet spot. No tools, just better sleep.

    The comfort behind every Koala mattress – Kloudcell®

    Kloudcell® is our signature comfort foam. It’s designed to balance soft cushioning with steady support, help reduce heat build-up, and respond easily as you move through the night.

    Soft and supportive

    So you feel cushioned, not stuck

    Kloudcell® foam gently cushions pressure points while staying supportive under broader areas like your back and hips, helping keep your body comfortable and aligned across different sleep positions. Its structure is designed to ease pressure at the shoulders, hips and knees without the sag or sink often associated with traditional memory foam.

    Breathable

    So heat doesn’t build up

    Kloudcell® allows air to flow through the mattress thanks to its open foam cell structure, helping excess heat escape so you sleep cooler and stay on top of the bed, not stuck in it like traditional memory foam.

    It’s tested to be up to 40% cooler to the touch and 30× more breathable than the worst-performing competitor foams.

    Instantly responsive

    So movement doesn’t interrupt your sleep

    Unlike slow-response memory foam, this fast-responding foam reacts instantly when you move, making it easier to change positions with less disturbance. It absorbs motion at the comfort layer, forming the foundation of our Zero Disturbance® motion reduction.

    Built to last

    So comfort holds up over time

    Kloudcell® is made with durable, high-density foam designed to hold its shape and comfort over years of use, delivering consistent comfort night after night.

      So lush but supportive. Love that i can can choose medium firm or a firm topper and the seasonal top piece. I had been on an ikea saggy old mattress and i so wish i upgraded sooner! No more back pain

      Came so quickly, and is so comfy. The mattress was easy to assemble (and my kids are still playing with the boxes lol) and has already made a huge difference to how we are sleeping. Now when my partner turns over in the night I barely feel it at all, if I even notice, and our bed base doesn't make much noise anymore either (it was so squeaky before with our twelve year old mattress)

      Firm, comfortable and cool mattress

      This firm mattress provides excellent support and keeps me properly aligned throughout the night. I no longer wake up sore and I feel much better rested in the mornings. It’s also great in eliminating partner disturbance and staying cool especially as a hot sleeper.

    FAQs about the Koala Polar+ Mattress

    How do PolarBands™ keep me cool?

    They are thermal bands that draw excess heat away from your body where it tends to build up most. This innovative tech is designed to keep you feeling cool for 8+ hours.

    Can I buy the seasonal topper on its own?

    The seasonal topper is an exclusive part of the Polar+ system. It's engineered to work perfectly with the internal cooling layers and is not sold separately.

    How do I switch the topper for the season?

    Simply unzip the topper, flip it to your preferred side (CoolThread™ or organic cotton), and zip it back up. Easy custom comfort for any season.

    How do I adjust the firmness feel?

    Unzip the topper, flip the double-sided Kloudcell® comfort layer to choose between medium or medium-firm, and zip it back up. Customise your support at home.

    Which firmness should I try first?

    We recommend starting with the medium side. If you need more support after a few nights, simply flip the comfort layer for a firmer feel. Easy to adjust!

    What makes the CoolThread™ fabric cool?

    It’s a special cooling yarn designed to feel instantly crisp and cool against your skin, while actively wicking away moisture to help you stay dry all night.

    How do I care for the seasonal topper?

    You can wipe it clean with a damp cloth. Please note that washing or dry cleaning 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.

    Who is the Koala Polar+ Mattress best for?

    Struggling with heat: Your absolute best solution for sleeping hot, thanks to the deep internal cooling power of PolarBands™ technology.

    Seasonal peace of mind: Never worry about being too hot or too cold—the simple-flip topper adjusts to your preferred climate instantly.

    Your perfect feel: You prefer to make the final firmness decision at home, choosing the right level of support for your body.

    The best investment:     You're ready to buy a mattress once and know you're getting the most advanced, fully featured Koala design.

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