    Overview

    The Sealy Sophia Luxury Flex mattress range offers the ultimate luxury: a deep, restful night of sleep. With its premium LuxeTop construction and Luxury Medium feel, this is the perfect option for those looking for a mattress that is not too soft, not too firm, but just right.

    Tried-and-tested comfort technologies and advanced support systems provide the perfect harmony between relief and relaxation. The SmarTex fabric regulates temperature, the HealthShield maintains a hygienic surface, while the premium wool fibre promotes breathability to create the ideal sleeping environment.

    Proper sleeping posture is essential and you’ll feel supported by the state-of-the-art Titanium RestSUPPORT to maximise stability and balance. In addition, the combination of supersoft and Sealy quilt layers, plus the deep premium foam, provide outstanding pressure-relieving comfort so you wake up every morning feeling refreshed.

    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 Luxe Base.
    Titanium RestSUPPORT

    This revolutionary three-stage coil system supports your body with perfect balance, helping to ensure a restful night of sleep. Engineered for durability, you can enjoy long-lasting sleep to help your mind and body rejuvenate each night.

    Deep Premium Foam comfort layers

    Quality sleep results from top-quality design and the Deep Premium Foam layer in this mattress gives a well-balanced feel. Designed with the Durabond Insulator to perfectly bring together the comfort layers and support system, this mattress provides long-lasting comfort.

    ComfortCore Plus

    Help keep lower back discomfort at bay. Enhanced with ComfortCore Plus, this mattress has a densified memory foam and gel infused visco-elastic layers to adapt and conform to your lower back, relieving pressure so you wake up feeling your best.

    Not so great after a few months
    Well, we've turned it every couple of weeks per instructions, and my Mother in law is now complaining of a lumpy bed... wife and I tried it, and it is, you can feel the springs in it. It was fine for the first few weeks. She has an adjustable bed base, which this is supposedly made for, but now we had to buy a very thick mattress topper so she doesn't have aches where more weight is on the springs. Disappointing for the price paid, we won't make that mistake again, we'll get a mattress we can look at first.
