    Overview

    You’ll feel the difference the moment you lay back on a Sealy Summer Flex mattress. From the luxurious foam and quilt layers, to the robust support system, you can feel your tiredness instantly melt away. With its TightTop construction providing a firm feel, this is designed to disperse weight evenly and reduce pressure on specific parts of your body.

    At its core, the sensitive SenseGel ComfortCore helps to minimise muscular tension, easing you towards a restful slumber. While you sleep, your body is kept well-aligned thanks to the intuitive AlignSupport system. The SmarTex fabric regulates temperature, the HealthShield maintains a hygienic surface, while the natural wool fibre blend promotes breathability to create the ideal sleeping environment.

    This mattress is designed with FlexiCased edge technology with an articulating perimeter to pair with Sealy’s adjustable bed bases including Energise and Inspire. Or create the bedroom of your dreams with Sealy’s SpaceSaver Drawer Base and Endurance Base.
    SenseGel ComfortCore technology

    Located in the centre-third of the mattress, the ComfortCore is enhanced with the ultra-sensitive, super-soft SenseGel material to conform to the shape of your body, helping to ease and alleviate tension while you rest.

    Titanium AlignSupport

    Tossing and turning is a thing of the past. Engineered to sense your weight and respond to ensure your body’s alignment, the durable Titanium AlignSupport has intuitive coils so you can enjoy deep, undisturbed sleep.

    Deep Cushioning quilt layer

    The quilt layer in this mattress cushions and conforms to your body to provide support and a super comfortable feel. This means you can wake up as good as new and ready to tackle the day ahead.

    Convoluted Firm Foam layers

    The deep layer of convoluted foam combines comfort with a firmer feel to help relieve pressure points. Designed with the Durabond Insulator to perfectly bring together the comfort layers and support system, this mattress provides long-lasting comfort.
