The Luxury Supreme mattresses are filled with natural fibres, such as British wool traceable to Waitrose and Red Tractor assured farms and responsive natural Talalay latex. Plus, plant-based comfort layers made from cotton, Himalayan allo and silk-like kapok. These fibres are naturally breathable, have temperature-regulating and moisture-wicking properties and offer supreme comfort. This No 1 model has a medium tension. ReActivePro™ Pocket Spring System The enhanced pocket spring system in this mattress provides support and pressure relief and helps to align the spine while you sleep to prevent aches and pains. The springs work individually, enhancing airflow so your mattress stays fresh and cool. Hypnos' Triple Edge Protection™ means the support spans the entire width of the mattress, so you have a wide sleep surface. Plus, the edge is reinforced with a genuinely hand side-stitched border and frame, with firmer edge springs to prevent rolling. Make the most of your new mattress Leave your new mattress to air in a well-ventilated room for a few hours to diffuse any natural scents from its fillings. Use a breathable mattress protector and air your mattress regularly. This mattress complements a sprung bed base to enhance its luxury feel, but if you have a slatted base, ensure the gaps are no more than 7.5cn apart. Follow the care instructions supplied.
