    Four reasons to love the Koala Plus Mattress

    • Advanced cooling. Deep sleeping.

      To fall asleep faster and stay asleep longer, our bodies need to keep cool. And the Koala Plus Mattress features our most advanced cooling tech yet. Cool-to-touch moisture-wicking fibres in CoolThread™ and breathable Cooling Gel Kloudcell® means the Koala Plus Mattress sleeps 13% cooler*on average than leading online mattress brands. Now that’s a game-changer.

    • +33% Kloudcell®

      Our Kloudcell® is the closest experience to floating on a cloud that you can have - and the Koala Plus Mattress boasts 33% more compared to the Koala Mattress and the SE Mattress. We like to think it feels like floating on a cloud, with marshmallows and teddy bears inside.

    • Seasonal Topper

      Our 2cm quilted topper is ready to tackle every season. You can simply unzip and flip it over to take you from comfy Organic Cotton when it’s chilly, to crisp CoolThread™ when it’s hot.

      Comfort

      Love it- right amount of firm, right about of soft!

      I'm a shift worker and to know I can crawl into bed anytime and snooze is the best. Also French bulldog approved!

      Best mattress ever!

      My wife and I had been looking to replace our current mattress for some time as we kept waking up with sore backs and poor sleep. After some research, we decided to purchase a koala mattress. I was a bit sceptical at buying one online without seeing it in a shop. The entire experience from online purchase to delivery was amazing. It was extremely simple to unbox and setup the mattress. We have been sleeping extremely well since the purchase. I have now purchased a Koala pillow, which is the best pillow ever. Highly recommend Koala products to anyone based on our experience!

      Excellent value

      Bought a king size mattress for our new home. Was a good price, adjustable and extremely comfortable. Easily set up, and good packaging.

    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.
