Every layer of this Silentnight mattress is designed for responsive comfort. A dual layer of 2,000 Mirapocket® springs reacts independently to your movements, providing personalised zoned support while distributing weight evenly across the mattress. The UltraGel® comfort layer cushions pressure points before springing back as you change position. A plush boxtop adds extra depth, while the breathable mesh border encourages airflow. The UltraGel® layer is up to five times more breathable than standard memory foam, and an anti-allergy treatment is scientifically proven to help reduce dust mite allergies. Handmade in the UK.
