The Millbrook Duke Natural Silk Mattress showcases exceptional British craftsmanship paired with luxurious natural materials. Designed to deliver balanced comfort and reliable support, it offers a medium tension feel and long-lasting quality for a truly restful night’s sleep.

Advanced 7-Zone Ergonomic Support
At the heart of the Duke is Millbrook’s 7-Zone Ergonomic Pocket Spring System, featuring up to 1000 individually responsive springs in a king size. Each zone is carefully designed to follow the body’s natural shape—providing gentler support at the shoulders and firmer reinforcement at the hips and lower back. This targeted structure promotes proper spinal alignment, reduces pressure points, and encourages deeper, healthier sleep.

Naturally Luxurious Fillings
Layers of Natural Silk, Fine English Cotton, and Sustainably Sourced Hampshire Wool combine to create a soft, breathable, and comfortable sleep surface. These premium natural fibres help regulate temperature, wick away moisture, and maintain a cool, fresh sleeping environment throughout the night.

Traditional Craftsmanship and Lasting Quality
Finished with a hand-tufted Damask cover, the Duke reflects Millbrook’s heritage of expert craftsmanship. UltraEdge™ reinforcement enhances edge support for a more stable, usable surface, while built-in air vents improve airflow to keep the mattress fresh. Practical turning handles make rotation easy, and the double-sided design allows for even wear over time, extending the mattress’s lifespan.

With a depth of 28cm and a 10-year warranty, the Millbrook Duke Natural Silk Mattress delivers a refined balance of comfort, durability, and dependable medium support—perfect for those seeking timeless quality and performance.
