    Four reasons to love the Koala Mattress

    • A hand pressing down on a white mattress surface, showcasing its plush texture.

      7cm Kloudcell® Comfort Layer

      The Koala Mattress has 17% more Kloudcell® than the SE Mattress. We’ve spent 8 years perfecting our unique Kloudcell® technology so you’re no longer forced to choose between soft or supportive comfort.

      Kloudcell® gently supports broad surfaces like your back, whilst also providing pressure relief across sensitive shoulders, hips, knees and feet.

    • Breathable Cover with TENCEL™ + Kloudcell®

      To fall asleep, our bodies need to cool down first. The Koala Mattress cover fabric is made with carbon-zero TENCEL™ Lyocell fibres that help absorb and release moisture, making nodding off a breeze.

      Under the cover, the Kloudcell® open-cell structure provides the breathability your body needs to sleep cooler and drift off faster.

    • Person adjusting a white mattress topper with a mint green mattress that has a "koala" label, in a bedroom with light wood furniture.

      Flippable Firmness

      Tired muscles, joint aches and pains, or sleeping hot?

      This is where the magic happens. The double-sided Kloudcell® comfort layer gives you the choice between medium-firm and firm at home, with both sides providing superior comfort and breathability. Simply unzip and flip to find your sweet spot.

    • Close-up of a mattress with a dual firmness feature. One side is labelled medium-firm, the other firm. Hands demonstrate the firmness levels.

      Partner Preference (Optional)

      Improve your sleep (and your relationship) with an optional Partner Preference comfort layer.

      Each side of the mattress is tailored to individual firmness levels — medium-firm for one, firm for the other. Perfect to bring you closer together (rather than driving you apart)!

    An award-winning sleep changes everything

    We know good night’s sleep can make your day. But a good sleep every night? Well, that can change your life. That's why we've upgraded Australia's top rated mattress. Not only is the Koala Mattress a ProductReview.com.au 2023 & 2024 award winner but it now comes with 17% more Kloudcell® for extra comfort. Plus the choice of flippable firmness or partner preference so you can customise your sleep.

    17% more Kloudcell®

    A little bit of Kloudcell® goes a long way. An extra 17% more Kloudcell®? Well, that’s enough to change the way you drift off at night. Our proprietary Kloudcell® technology offers the superior support, breathability, responsiveness and durability you need to fall asleep faster and stay asleep longer.

    Flippable firmness

    Falling asleep should never be hard. But it can be firm. Or medium-firm. Yep, you can choose. Change up the firmness with our double-sided comfort layer. Just unzip and flip to find your sweet spot.

    Partner preference

    Two words that’ll change your life in so many ways; Partner. Preference. It’s here. If you and your partner can’t agree when it comes to bed time - we’ve designed an optional comfort layer with half firm and half medium-firm Kloudcell®. No more complaints, just a perfect sleep on both sides of the bed.

    Zero disturbance®

    Sleeping with a tosser? You don’t need to change partners to get a good night’s sleep. Just upgrade (your mattress). With 3 targeted support zones, you'll sleep soundly no matter who you sleep next to.

      Fantastic mattress

      My husband and I have been sleeping on koala for years now. We finally decided to upgrade to a queen during a move, and WOW is it comfortable. It’s soft, breathable, and feels amazing every morning we wake up! Truly couldn’t recommend something more for those looking for a good mattress at an affordable price

      Super comfy with great support

      after procrastinating for ages on a new bed an mattress I decided to try Koala after a recommendation from my son. The full refund if you don’t like it gave me some additional comfort with my purchase not having the opportunity to see one in person. The mattress did not disappoint. It is super comfortable whist still giving great support. Very happy with this purchase

      KOALA to the rescue

      My mattress was delivered within a couple of days of ordering. After sleeping on it for a couple of night, I realized that it was a bit firm for me. I contact leisl in the customer service team to see if I could purchase an alternate topper… and oh my god the service! I was send a complimentary mattress topper which I also received within a few days of my feedback,. My mattress is now perfect. love you Koala.

      so easy!

      the koala matress was so easy for me who lives alone to unbox and put on my bed. I can lift it on my own and it is so comfy. I selected a flippable and I prefer the firmer side for more support.

    Frequently asked questions

    How does the Koala Mattress feel? How supportive is it?

    The Koala Mattress and Koala Plus Mattress are designed with versatility in mind, featuring a flippable comfort layer that allows sleepers — whether they prefer lying on their front, side, or back—to choose between medium-firm and firm comfort levels at home. Additionally, the Koala Mattress offers the option to include a half-and-half comfort layer, catering to couples with differing firmness preferences and sleeping positions.

    Every Koala Mattress is designed with a sophisticated base of ergonomic support zones, each tailored to contour the body's natural curves and promote healthier spinal alignment for life changing sleep. The Koala Mattress features three high-density targeted support zones positioned under the torso, hips, and legs to offer enhanced support where it's most beneficial.

    The Koala Mattress also features 17% more Kloudcell® than the Koala SE Mattress, for better support, breathability, responsiveness and durability. The Koala Mattress has been engineered to provide stability under broad surfaces like your back, but it is flexible enough to support your hips and shoulders in any sleeping position.

    What's the difference between Flippable Firmness and Partner Preference?

    The Koala Mattress and Koala Plus Mattress are designed with versatility in mind, offering a Flippable Comfort Layer that allows sleepers — whether they prefer lying on their front, side, or back—to choose between medium-firm and firm comfort levels at home. Additionally, the Koala Mattress offers the option to include a Half-and-Half Comfort Layer, catering to couples with differing firmness preferences and sleeping positions.

    Here's how they work:

    Flippable Firmness (Standard)

    Adjust your comfort level at home.

    Falling asleep should never be hard. But it can be firm. Or medium-firm. Yep, you can choose.

    A double-sided Kloudcell® comfort layer gives you the choice between medium-firm and firm at home. Simply unzip and flip to find your sweet spot.

    Partner Preference (Optional) - Half medium-firm, half firm

    Half medium-firm, half firm

    If you and your partner can’t agree when it comes to bed time - each side of the mattress can be tailored to individual firmness preferences — half medium-firm, half firm.

    The Partner Preference comfort layer can be rotated so your comfort preference is always on your side of the bed. Perfect to bring you closer together (rather than driving you apart)!

    Can I get both Flippable Firmness and Partner Preference?

    Unfortunately not, but if you've purchased a Koala Mattress with Flippable Firmness and you'd like to change to Partner Preference, just give our friendly Customer Support team a call!

    What is Kloudcell®?

    Kloudcell® is what quality sleep is made of. With its superior support, breathability, responsiveness and durability, Kloudcell® is the closest experience to floating on a cloud that you can have.

    Every Koala Mattress uses Kloudcell® technology in the comfort layer, but the Koala Mattress and Koala Plus Mattress models also feature Flippable Firmness, so you can choose between medium-firm and firm Kloudcell® at home. Couples with different firmness preferences can add a Partner Preference comfort layer to their Koala mattress, featuring half medium-firm and half firm Kloudcell®. For the plushest comfort, the Koala Luxe Mattress features 3cm of Kloudcell® quilting, and has 50% more Kloudcell® than the Koala SE Mattress.

    As Australia’s most awarded mattress range with over 50,000 five-star reviews, falling asleep faster and staying asleep longer is as good as a sure thing. Learn more.

    Which side of the Koala Mattress with Flippable Firmness should I try first?

    We recommend trying the medium-firm side first, and giving your body a few days to adjust before trying out the firm side. Just like a new pair of shoes, it may take a few days to feel just right!
