Millbrook Duke Natural Silk Mattress - EU King

• Sleep Surface. A Belgian damask viscose cover that feels silky rather than scratchy against bedding. It's highly breathable, which means moisture escapes rather than lingering, helping the bed feel fresher night after night.
• Natural Silk Layer. Silk is lightweight and exceptionally soft, which means a gentle, cushioned first impression when you lie down. It's a genuine luxury filling rather than a marketing flourish.
• Sustainably Sourced Hampshire Wool. Wool is naturally elastic and durable, which means the cushioning recovers its shape rather than flattening quickly. It also regulates temperature well, a quiet advantage if you run warm.
• Fine English Cotton. Premium English-spun cotton, crafted in the North West of England, adds a soft, breathable comfort layer. Cotton wicks moisture, which means a drier, more comfortable sleeping surface.
• Support System. A 7-zone ergonomic pocket spring system with up to 1000 individually responsive springs in a king size, designed to mirror the body's natural contours. Softer cushioning at the shoulders and firmer support through the hips means better spinal alignment, particularly for side sleepers.
