    Overview

    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. This mattress has a EuroTop construction with a plush feel, so you can feel at ease when you’re sleeping and relaxing.

    The premium wool fibre adds softness and promotes breathability to create the ideal sleeping environment.
