    Overview

    1:37
    The Sealy Lua Mattress range draws from years of sleep innovation and expertise to give you support that stands the test of time. Feel refreshed every morning thanks to Sealy’s CoreSupport coil technology, which offers excellent support throughout the night. With its EuroTop construction and medium firmness, this is the perfect option for those looking for a mattress that is not too soft, not too firm, but just right.

    The premium wool fibre adds softness and promotes breathability to create the ideal sleeping environment. This is combined with the SuperSoft and Sealy quilt layers which offers pressure relief and cushioning comfort. The high-density gel foam centre relieves pressure on the lower back to help prevent you feeling stiff and sore.

    Pair this mattress with the Sealy Performance Base with FlexSteel modules to create a sleeping solution that works like a dream.
    CoreSupport system

    Sealy’s CoreSupport system is engineered to provide deep support and greater durability. This alternating single-stage coil system has six turns for conformance and is twice-tempered to offer lasting support for your body.

    UniKey edge design

    Designed to provide an edge-to-edge sleep surface, the Unikey design helps to reinforce the mattress, providing a stable seating edge and support system.

    Deep Premium and Cushioning Foam Comfort Layers

    Quality sleep results from top-quality design and the Deep Premium and Cushioning Foam layers in this mattress gives outstanding conformance, enabling you to sleep soundly and comfortably.

    Supersoft and Sealy quilt layers

    Experience enhanced pressure relief, thanks to the high-density foam used in the Supersoft quilt layer. Plus, the Sealy quilt layer provides a plush feel so you can enjoy luxurious comfort with each night’s sleep.
