Layer Details
Cover
A soft knitted cotton-viscose cover that enhances airflow, which means heat escapes rather than building up at the surface. It feels gentle from the first night.
Comfort Layer
Layers of 100% Hampshire wool, naturally durable, springy and heat regulating. Wool keeps you warmer in winter and cooler in summer, a real benefit for hot sleepers.
Comfort Layer
Natural cotton fibres that regulate body temperature while wicking away moisture. This keeps the sleeping surface feeling fresh rather than clammy.
Core
A 100% recycled NemoFlex™ core made from recycled polyester using over 200 plastic bottles. It provides edge-to-edge support, so you can use the full width of the mattress.
Support System
3000 traditional pocket springs encased in cloth pockets that adapt to your movement. Each spring works independently, which means less disturbance from a restless partner.
