    Overview

    The Flynn range brings a balanced blend of support and comfort, offering a medium feel that suits a wide range of sleep preferences. Whether you’re a side sleeper, a combination sleeper, or simply looking for an all-rounder mattress, Flynn delivers the reliable comfort you need for restorative rest.

    At the heart of every Flynn mattress is the CoreSupport spring system—an exclusive, Sealy-engineered design that features a single-stage, six-turn coil structure. This durable, twice-tempered coil technology provides deep-down reinforcement while still offering subtle conformance to your body’s natural contours. The result is support that feels responsive yet reassuringly stable.

    To complement this support system, Flynn features EdgeGuard technology. This perimeter support module enhances edge-to-edge stability and expands the usable sleep surface, so you can move freely across the mattress without compromising support.

    HealthShield antimicrobial treatment is integrated throughout the comfort layers, maintaining a fresher sleep environment by helping to reduce allergens and bacteria over time. Each component is carefully tested to ensure lasting resilience, giving you the confidence that your mattress will perform night after night.

    Paired perfectly with Sealy’s designer, adjustable, or drawer storage bases, Flynn represents a smart, value-driven choice for comfort seekers who want reliable performance and premium features—all delivered with trusted Australian craftsmanship.

    Happy customer.
    Very comfortable mattress, not too firm not too soft. Good support across the surface and towards the edges. We bought when this was discounted so were very happy with the price. Good quality mattress from SEALY that does what it says in description. Also happy with Appliances online with free delivery and collection of old mattress.
