The 6ft Prestige Cushion Top mattress from Silentnight has a soft knitted stretch fabric cover & features their Miracoil spring system & a firm support. The mattress upholstery has a micro quilted top panel with generous layers of hypoallergenic & dust mite resistant fillings below for a healthier night’s sleep. The layers of fillings include ‘ Eco Comfort Fibre’, a scientifically proven fibre that dramatically reduces heat build up & also provides pressure relieving comfort. Silentnight's patented Miracoil system has springs that are connected from head to toe distributing weight up & down the mattress instead of across it. This creates individual sleep zones giving each person an undisturbed sleep. Edge to edge support gives you a wider sleeping surface – you can sleep comfortably right up to the very edge of the mattress without the sensation of rolling off. Also extra springs are concentrated in the centre third of the mattress to create a supportive Posture Zone just where the body needs it most. In fact there is more than double the number of springs in a Silentnight mattress than in a standard open coil spring unit. The mattress is designed to be one-sided (non turn) & does not require to be flipped over, but does need to be rotated from head to toe regularly. Head to toe support & additional support exactly where your body needs it. That's the Silentnight Miracoil way, & a hugely successful way it is too.
