Rare breed and indigenous wools including the Romney are combined with other British wools and are layered with natural fillings such as Egyptian cotton and viscose for a mattress to take you through the seasons. Targeted support comes from a central Cortec™ spring system working alongside Posturfil, HD 4000 and Microlution 5000 Airflow springs, to give a 23800 spring count. Three rows of mattress side stitching and a True Edge divan base offer stability across the whole sleeping surface.
