      Super comfortable mattress

      We are very impressed with this mattress. It is super comfortable, easy to lift when making the bed and hasn't been any trouble for my sore, aging hips. Highly recommend!

    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.
