    Make it a set

    Four reasons to love the Koala SE Mattress

    • Kloudcell® — soft & supportive

      After 8 years of perfecting Kloudcell® technology, you no longer have to choose between soft or supportive. Kloudcell® offers gentle support for your back and relieves pressure on shoulders, hips, knees, and feet—soft where you want it, supportive where you need it. Ideal for both back and side sleepers.

    • Soothing TENCEL™ Cover + Kloudcell®

      To fall asleep, our bodies need to cool down first. The Koala Mattress cover fabric is made with TENCEL™ Lyocell fibre that helps absorb and release moisture, making nodding off a breeze. The Kloudcell® open-cell structure provides the breathability your body needs to sleep cooler and drift off faster.

    • Woman in light clothing lying on a bed with a wooden frame and white mattress. Neutral-toned room with beige walls and white curtains.

      3 zone support

      Responsive support where you need it most. The durable 3-Zone Support design aligns to your shoulders, hips and feet for enhanced pressure relief, with Kloudcell® responding to movement to keep you continuously supported and undisturbed throughout the night.

    • Close-up texture of a white mattress cover with a quilted pattern and small perforations, showcasing soft, breathable fabric surface.

      Koala Comfort

      Recently, we upgraded our bedroom mattress to a king. It has taken me a few weeks to get used to this mattress. Now, I sleep well. And so good to have the space and not to get any movement when your partner or self turn in for the night or wake early.

      LOVE IT!!!!

      This is my first time using a Koala bed and I can't tell you how good it is! From the super impressive next day delivery, to the easy set up.....to the comfort of the bed and the great mattress material- everything is top level! We purchased it for the spare room but have loved it that much, we use it often ourselves!

      No more rolling to the middle of the bed!!

      My husband and I both love the Koala mattress. It's firm, but so, so comfortable!!

      We are not in the process of replacing our teenage son's mattress, as he is increasing rapidly in size, we want him to have a mattress that will support his growing body!!
