Pairing Silentnight Miracoil spring with a deep eco comfort layer, the Sage mattress has been manufactured with comfort in mind. 

Miracoil Spring

The Sage mattress features Silentnights expertly engineered Miracoil spring system which provides double the support of a standard open coil spring. 

With zonal support, the springs in the hip area feature a slightly firmer spring in order to ensure additional support and assist in spinal alignment. 


Ideal for back or side sleepers, the Sage mattress is a medium to firm tension. 

Eco Comfort Layer

Nestled above the Miracoil system is a deep eco comfort layer, not only does this add a comfort layer, the fibres used promote increased breathability throughout the mattress ensuring it keeps that fresh feel. 

Purotex Cover

In order to ensure a healthier night’s sleep, the Sage features a Purotex cover which provides a barrier against allergens and dust mites ensuring your mattress keeps that fresh feel for years to come. 


Silentnight are so confident in the quality of their mattresses they provide a 5 year guarantee.
