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.

    Fixed quilted topper

    The New Koala SE Mattress features a fixed quilted topper that’s extra plush for that float-on-top feeling.
