By combining their patented Miracoil spring system, generous comfort layers and a deep pillow top, Silentnight have created a supportive and extremely comfortable mattress. 

Its layers of hypo-allergenic fillings include ‘EcoComfort Fibre’, a scientifically proven fibre that provides pressure relieving comfort and dramatically reduces heat build up.

At the core of the mattress is its unique Miracoil spring system that benefits from 3 firmness zones, providing extra support for your neck, shoulders and lower back. 

The springs are connected from head to toe, distributing weight up and down the mattress instead of across it. This creates individual sleep zones for an undisturbed sleep.

Extra springs are concentrated in the centre third to create a posture zone, just where you need it most. Edge to edge support allows you the full use of the mattress width.

Unlike dual-sided mattresses, the Luss does not need to be flipped over, but regular rotation will enhance its performance and help to prevent uneven wear and tear.
