The Millbrook Duke Natural Silk Mattress embodies refined British craftsmanship and natural luxury in perfect harmony. Combining sumptuous materials with precise, tailored support, the Duke offers medium tension comfort and enduring quality for a restorative night’s sleep.

Advanced 7-Zone Ergonomic Support

At its core, the Duke features Millbrook’s 7-Zone Ergonomic Pocket Spring System with up to 1000 individually responsive springs (in a king size). Each zone is designed to mirror the body’s natural contours — offering softer cushioning at the shoulders and firmer reinforcement through the hips and lower back. This balanced support helps maintain spinal alignment, ease pressure points, and promote deep, healthy rest.

Naturally Luxurious Fillings

Expertly layered with Natural Silk, Fine English Cotton, and Sustainably Sourced Hampshire Wool, the Duke delivers exceptional comfort and breathability. These natural fibres work in harmony to regulate temperature, wick away moisture, and create a cool, fresh sleeping environment with a soft, indulgent feel.

Traditional Craftsmanship and Lasting Quality

Finished with a hand-tufted Damask sleep surface, the Duke reflects Millbrook’s heritage of meticulous design and craftsmanship. Millbrook UltraEdge™ reinforcement provides edge-to-edge stability and maximises usable sleeping space, while air vents enhance airflow and freshness throughout the mattress. Turning handles allow for easy rotation, and the double-sided construction ensures even wear and lasting comfort.

At 28cm deep and backed by a 10-year warranty, the Millbrook Duke Natural Silk Mattress offers a perfect blend of natural materials, handcrafted excellence, and reliable medium support — a true hallmark of British bedmaking tradition.
