Layer Details
Damask cover
A finely woven, durable fabric that feels soft to the touch, which means the firmness underneath isn't harsh against your skin. It doesn't retain heat, so it helps keep the surface cool.
Eco Comfort Fibre
A layer of fibres made from recycled materials that gives cushioning comfort over the springs. It also helps evaporate body heat, which means a cooler night if you tend to run warm.
Miracoil Springs
Silentnight's own open coil system with separate support zones that support the spine and distribute your weight evenly. In practice, that means firmer support where you're heaviest and less pressure on hips and shoulders.
