    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.

    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.

      It’s so good!

      We are only 3 weeks in- but we love the new mattress. We got the dual medium/firm mattress - and we have been sleeping really well.

      The medium is a lot firmer than we anticipated- but that’s not bad- it’s still ridiculously comfy- just not sure we will have a need for the firmer setting!

      Indulgent!! We ummed and ahhed for a long time about which mattress to get!

      Just jump in and get it! It’s worth it

      Best mattress!

      This mattress is a game changer! Its the best night sleep my husband and I have had in years (and our last one was pretty pricey). The Polar+ layer makes a significant difference on those hot nights in keeping your body temp steady and cooler. HIGHLY recommend!

      Best mattress ever

      We purchased a King and King Single Koala Plus Mattress. After months of back, neck and shoulder pain I have enjoyed 2 months now of painfree sleep. The mattress is fantastic. And with our QLD summer the cooling insert has worked a treat - no sweating through the night. And as for movement - there is none, as in, my large husband who likes to throw himself over when he turns, does not disturb me anymore. As for making the bed - it's a breeze. It's not heavy so I can lift the corners easily to fit the sheets on. We will never go back to the heavy inner spring coil mattress. We are intending to purchase more Koala mattresses for the other beds in the house.

      Also a shout out to the customer service and communication. It was excellent - and we ordered our mattresses during the Christmas New Year period and still received prompt service.

    FAQs about the Koala Plus Mattress

    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.

    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.

    Best for
    • Sleepers who struggle with temperature fluctuation, thanks to its advanced cooling features and moisture-wicking CoolThread™ fibres.
    • Those who want seasonal adaptability, featuring a reversible "seasonal topper" with a warm organic cotton side for winter and a crisp cooling side for summer.
    • People unsure of their ideal firmness, as it offers a flippable comfort layer to switch between medium-firm and firm support.
    • Customers looking for advanced ergonomic support, provided by a 5-zone design that targets key areas of the body.
