      Amazing Mattress & Service

      This is arguably the best mattress we have had so far. We sleep so well on it.

      The buying process was also very efficient. The mattress was delivered on the same day we ordered. What a customer service.

      Good sleeps so far!

      Hello! My wife and I have been really enjoying this mattress so far. We previously had a Koala, which developed a dip after about five years, so we’re hoping this one holds up better over time. The extra topper definitely adds a noticeable level of comfor, we're sleeping great!

      Faultless!

      We can’t fault our Koala mattress. It’s our second one that we have bought and they are just the best. Cool, comfortable and luxurious. My wife and I have very different preferences in mattresses, yet this one seems to tick all the boxes for both of us. Being able to choose your delivery time and date is also such a bonus.

      Would love if Koala had a mattress recycling service for future!

    Frequently asked questions

    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.
