    Four reasons to love the Koala Plus Mattress

    • Proven to sleep 13% cooler.*

      CoolThread™ wicks moisture and cooling Kloudcell® foam balances your temperature. Fall asleep faster and stay asleep longer.

    • 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.

    • Close-up of a white reversible mattress pad with green edging, featuring "Summer" and "Winter" labels for seasonal use.

      Adaptable all year

      Simply unzip and flip for comfort. Choose soft Organic Cotton for chilly nights or crisp CoolThread™ for warmer weather.

    • Dual-comfort Kloudcelll® layer

      The double-sided Kloudcell® foam layer offers medium-firm or firm. Just unzip and flip the layer to easily find your sweet spot.

    Koala's most advanced mattress

    The Plus means more. More cooling. More Kloudcell®. More comfort. More support. With all this plus more, you’ll be sleeping pretty, not sweaty.

    Reversible mattress with white fabric, green piping, and "Summer" and "Winter" tags for seasonal use.

    Advanced cooling for better sleep

    Cool-to-touch CoolThread™ wicks moisture, while breathable Cooling Gel Kloudcell® keeps you comfortable. This advanced tech helps you sleep 13% cooler* and stay asleep longer.

    Adaptable comfort, all year

    Your quilted topper has two feels built-in. Simply unzip and flip for your ideal climate: cosy organic cotton when it’s chilly, or crisp CoolThread™ when it’s hot.

    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.

    FAQs about the Koala Plus Mattress

    How do I change the seasonal topper?

    To adapt for cool summer sleep or cosy winter warmth, simply unzip, flip the topper to the desired side, and close the zipper. It's that easy.

    How do I change the firmness?

    Your comfort, your choice. Unzip the cover and flip the internal layer to select your perfect feel: medium or medium-firm. Zip back up and relax.

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

    We recommend a gentle wipe with a damp cloth. Please avoid washing or dry cleaning—it can permanently damage the Kloudcell foam.

    Who is the Koala Plus Mattress best for?

    Seasonal adaptability: Anyone who struggles with temperature swings and needs a bed that's always cosy or cool.

    Your perfect feel: You want the power to adjust from medium-firm to firm at any time during your trial.

    Deep comfort: Sleepers who love the feeling of Kloudcell® cushioning pressure points while keeping their back well-supported.

    The innovation seeker: Best for those who value award-winning design and Koala's most advanced technology.

    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.

    What is Kloudcell®?

    Kloudcell® is our responsive foam that delivers cushioned comfort with steady support. It's designed to relieve pressure points where you need it most.
