    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.

      The best mattress ever!

      I love my Koala plus mattress. I have a connective tissue disorder and chronic pain and this mattress gives me the best support and comfort. The company is amazing and their customer support is exceptional. After our recommendation to my parents in law, they bought one and love theirs too. Thanks Koala!

      Comfortable mattresses even better customer service. I wouldn't hesitate to recommend this company to anyone. I had a delivery issue that was rectified immediately and a sale price match was given after I purchased the item a week before a sale. You can't do better than that for your customers!

      So good, it's a requirement

      Having had a Plus Mattress for over a year now, together with the occasional night on other mattresses, it's very easy for me to say this is the best mattress I've ever had. From the moment you lay down on it, you can feel the super plushness of the Plus Mattress without sacrificing any support. As a side-sleeper, this combination is a must have.

      The mattress is so good, I've buying another for my child.

      Flexible with movement and function

      I love the flexibility of changing the firmness, and the zip and tags make it so simple to do. As advised in booklet, it food take about 3 days to develop it's structure but it was still great to sleep on from day 1. I would recommend / buy again.

      No bedframe no worries

      Despite still waiting for my bedframe to arrive, I would hardly notice because this mattress is so cosy! Plenty of support and the right amount of snug. My back is very pleased with the Koala plus.

    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.

    The Koala Plus mattress on average sleeps 13% cooler when compared to leading online mattresses competitors. Based on independent testing in a climate controlled lab using proprietary technology to simulate human thermoregulation.
