Layer Details
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.
