    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.

      Beautiful as I knew it would

      I’ve slept on this new mattress of mine for every night since I ordered it & loving it and I didn’t doubt I would 😁 for I do have a king koala I’ve had for about 5 years and absolutely the #1 favourite thing I own. I had to do to unforeseen circumstances put the king in storage and homeless for 4-6 months I developed terrible back pain from missing my koala as i also have conditions such as slipped discs and EDS and this mattress is just heavenly for these conditions by the way. Once I got a place to live it came with a double bed and after a couple weeks in it I woke up one morning in excruciating pain in my hip I cried trying to roll over certain id have a pressure sore and thought I couldn’t bare that next night on that bed. Placed my order before 8am and it arrived a bit after 3pm and I’m so grateful I love you guys I brag about my bed(s) to everybody! Haha thank you koala love you lots x tay

      Koala SE Mattress

      I recently purchased the Koala SE Mattress for my spare room. Right from choosing the mattress on the website to the order delivery and processing the whole experience was fantastic. I ordered the mattress in morning and it came the same day in the evening which was fantastic. The mattress itself is very comfortable and the return policy is excelllent.

      This is my second koala mattress and thoroughly satisfied.
