    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 firm feel, you can help reduce pressure on your body for a more restful night of sleep.

    The premium wool fibre adds softness and promotes breathability to create the ideal sleeping environment. This is combined with the Deep Cushioning quilt layers to conform to your body and increase 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.

    Convoluted Firm and Cushioning Foam layers

    The deep layer of convoluted foam combines comfort with a firmer feel to help relieve pressure points, while the layer of cushioning foam enhances conformance.

    Deep Cushioning quilt layer

    The quilt layer in this mattress cushions and conforms to your body to provide support and a super comfortable feel. This means you can wake up as good as new and ready to tackle the day ahead.
