Sealy Back Support Harmony Deluxe Mattress

Sealy Back Support Harmony Deluxe Mattress - Medium

If you love sleep as much as we do, then it’s easy to appreciate the balance of comfort and support offered by Sealy’s Back Support Harmony Deluxe mattress. Proudly made in Australia, this luxurious mattress is designed for those who prefer a medium feel.

CoreSupport features in the centre-third of the mattress, a gel-infused, single-stage (spring) support system aiming to improve conformance with the help of premium comfort layers. Stabilised along the perimeter with UniKey®, an element designed to maximise the sleep surface and provide the mattress with added durability.

Finished with a plush pillowtop and a breathable stretch-knit fabric for enhanced comfort, there’s surely nothing that creates excitement at bedtime quite like a Sealy mattress.
