      Koala Queen Plus Mattress

      Glad we purchased this mattress as it’s much lighter than a spring mattress and being retirees it’s easier to lift and to make up daily

      When getting up from the mattress or turning over there is nil to minimal partner disturbance.

      A great purchase and customer service from Koala.

      Comfy, Quality Mattress

      This mattress is comfy and helps to keep me a bit cooler than I would usually be during the night. I like a firm mattress and have the topper on ‘medium’ rather than ‘firm’. I loved how it was delivered in a roll!

    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.
