Silentnight Vilana Limited Edition Miracoil Mattress - UK Super King

• Knitted cover. A soft knitted finish that adds a touch of cosiness and warmth. It also helps airflow, which means less heat building up around you overnight.
• Soft White Fibres. Soft synthetic fillings that give the surface its cosy feel while staying durable and resilient. They're designed to hold their shape rather than flatten quickly.
• Dense polyester fibres. Tightly packed fibres that provide secure cushioning without letting you sink in too deep. This is where the extra firm character really comes through.
• Miracoil Springs. Silentnight's open coil system with separate support zones, which means your weight is spread evenly and your spine is supported where it needs it most. The zoning helps relieve pressure while you sleep.
