Layer Details
Sleep Surface
A Belgian damask viscose cover that feels silky and soft to the touch. It's highly breathable, which means a fresher sleeping environment through the night.
Comfort Fillings
Sustainably sourced Hampshire wool sits beneath the cover, giving a cosy, cushioning feel. Wool is known for its durability and elasticity, so this layer should keep its shape well.
Comfort Fillings
A layer of fine English cotton, spun and crafted in the North West of England. Cotton adds softness and helps the mattress breathe.
Support System
7-zone ergonomic pocket springs, up to 1000 individually responsive springs in a king size, with the count varying by size. The zoning gives softer comfort at the shoulders and firmer support at the hips and back, which means better spinal alignment for most sleepers.
