    The comfort behind every Koala mattress – Kloudcell®

    Kloudcell® is our signature comfort foam. It’s designed to balance soft cushioning with steady support, help reduce heat build-up, and respond easily as you move through the night.

    Soft and supportive

    So you feel cushioned, not stuck

    Kloudcell® foam gently cushions pressure points while staying supportive under broader areas like your back and hips, helping keep your body comfortable and aligned across different sleep positions. Its structure is designed to ease pressure at the shoulders, hips and knees without the sag or sink often associated with traditional memory foam.

    Breathable

    So heat doesn’t build up

    Kloudcell® allows air to flow through the mattress thanks to its open foam cell structure, helping excess heat escape so you sleep cooler and stay on top of the bed, not stuck in it like traditional memory foam.

    It’s tested to be up to 40% cooler to the touch and 30× more breathable than the worst-performing competitor foams.

    Instantly responsive

    So movement doesn’t interrupt your sleep

    Unlike slow-response memory foam, this fast-responding foam reacts instantly when you move, making it easier to change positions with less disturbance. It absorbs motion at the comfort layer, forming the foundation of our Zero Disturbance® motion reduction.

    Built to last

    So comfort holds up over time

    Kloudcell® is made with durable, high-density foam designed to hold its shape and comfort over years of use, delivering consistent comfort night after night.
