Like the other mattresses in the Stress Free collection the Stress Free Supreme uses an open coil spring technology. The Stress Free Supreme is firmer than the Stress Free and incorporates additional layers of wool and other luxury paddings to create a truly exquisite effect. As well as utilising a unique cover that promotes airflow, there are air vents and turning handles on both sides of the mattress. The Stress Free Supreme gives you a soft, sumptuous feel while helping you to keep cool during your sleep. The matching divan base comes with end or side storage in any combination.
