    Overview

    Florence represents the pinnacle of precision-engineered sleep, offering a mattress experience designed to align your body, relieve pressure, and enhance nightly recovery. Built to orthopaedic specifications, this advanced sleep solution integrates the latest in responsive coil and comfort technology.

    At the core of Florence lies the ReactSupport system—a two-stage ultra-sensitive coil setup that delivers superior conformance and support. The surface layer features SynerFlex for micro-level pressure relief, improving initial comfort by up to 14%. Beneath, responsive touch points adjust to your body’s shape, ensuring full-body alignment and reduced motion transfer.

    Enhanced comfort continues with a central ComfortCore zone, upgraded in Florence with SenseGel Material for an elevated level of pressure relief and temperature control. This layer targets the lower back, reducing stress on key joints and promoting a balanced sleep posture.

    Wrapped in SmarTex fabric, Florence actively regulates moisture and temperature to maintain a consistently cool, breathable sleep climate. FlexiCased edge support reinforces the entire mattress perimeter, maximising the usable sleep surface while maintaining durability and compatibility with adjustable bases. The integrated BasePlank structure also provides shock absorption and mattress stability, especially when paired with slatted bases.

    Florence is a superior choice for sleepers who demand luxury-level comfort with functional, clinically-inspired support—engineered for performance, designed for wellbeing.
