    Breathable FusionCool™ cushioning

    We wanted the coolest, most luxurious comfort layer for the top of our Ultra – so we made FusionCool™. Blending wool, charcoal, bamboo and kapok, it provides silky-soft cushioning that’s naturally breathable, allowing air to flow and preventing heat build-up, keeping you cool and dry.

    Boosting PureLift™ layer 

    We combined latex and coconut to create the springy PureLift™ support layer in our Ultra. When blended together, they form a comfortable layer that’s bouncy, breathable and adapts to your body shape – taking the pressure off so you feel fully supported.

    Maximum spring count, maximum comfort

    What’s behind our “sleeping-on-a-cloud” feel? Our titanium alloy Aerocoil® microsprings. We proudly place them at the top of our Ultra, where comfort matters most, and there’s up to 3,800 in two layers – plus an extra layer of up to 2,500 – for ultimate, pinpoint support. As they compress individually, they push fresh air upwards and respond separately to movements – so you feel cooler, and your partner’s toss-and-turns stay on their side.

    Two ‘cooler feel’ Simbatex® layers

    Intertek tests in May 2025 on nine memory foams from the top three UK manufacturers compared to Simbatex® using single pieces of foam to ISO 7231 010 Method B Determination of Air Flow value at constant pressure drop.

    If your mattress makes you feel too hot at night, your quality of sleep suffers. But our Simbatex® foam has over 5x more airflow than memory foam , and it’s infused with graphite to move warmth away from your body. Our Ultra exclusively has two luxurious layers, so you get all the comfort of memory foam – minus the heat.

    What is a Hybrid®?

    (And why Simba is the King of Hybrids!)

    Hybrid mattresses combine foam and springs. Foam mattresses give a restful, cradled feel but can feel soft, hot and lack support. Spring mattresses sleep cooler and provide robust support but can feel bouncy and hard. Hybrids provide the cradled feel without the bounce and sleep cooler.

    Simba Hybrids® uniquely have microspring Aerocoil® layers at the top of the mattress. These provide our unique Simba feel and so you feel ultimately comfortable, supported and cool.

    Ideal firmness, optimum support

    We’ve designed all our mattresses to feel ‘medium-firm’, as it’s what studies have shown offers best sleep quality and support. Simba mattresses offer a ‘hugged’, cradled feeling in the top layers and firmer support in the base layers.
