Layer Details
Top comfort layer
An Egyptian cotton and flax blend that wicks away excess moisture, which means you're less likely to wake up feeling clammy. Both are naturally breathable fibres.
Mid comfort layer
Egyptian cotton, kapok and alpaca wool work together to regulate temperature. In practice that means a cooler feel in summer and a cosier one in winter.
Viscose wool layer
A viscose wool blend derived from the wood pulp of eucalyptus, beech and pine trees. It helps regulate temperature and promotes airflow through the mattress.
Spring system
At the centre sits a layer of Cortec pocket springs with four layers of micro springs and micro ultra springs. Layered springs like these respond to your body in finer detail than a single spring unit, so support feels more tailored.
