    Overview

    The Sealy Sophia Luxury Flex mattress range offers the ultimate luxury: a deep, restful night of sleep. With its TightTop construction providing a Luxury Firm feel, this is ideal for sleepers who require a firmer surface. Designed to disperse weight evenly and reduce pressure on specific parts of the body, you can wake up feeling restored.

    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 the cushioning quilt layer plus the premium and cushioning foam layers, creates a supportive and comfortable feel.

    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.
