      Extremely Comfortable

      This is the most comfortable mattress I have ever bought. In the past I have purchased more expensive mattresses and have to say this is just as good if not better. Not only is it a fabulous product but was so convenient and efficient. I ordered it online and in 2 days it arrived. Was also super easy to unpack.

      Can't be beaten

      This is the 2nd mattress we've purchased from Koala and they can't be faulted. It's such a supportive and comfortable mattress that easily beats other larger heavy hitters on the market, it really does take the stress out of a long day.

    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.
