Silentnight have gone above and beyond to find a new way a mattress can deliver strong support. It’s a system of interwoven springs that run vertically (head-to-toe) along the bed, whereas normally they run horizontally in an open coil spring system. Overall it offers a firmer support and prevents ‘roll-together’ that often occurs on the other styles of mattresses. This mattress has a medium-firm firmness rating so it doesn’t sacrifice comfort either. On top of this, the mattress’ support is arranged in a way which targets key areas of the body that are under pressure most of the day, such as the knees, hips and shoulders.
