The 800 pocket Sovereign mixes generous layers of conventional fillings with the advanced technology of 40mm visco-elastic fibre, more commonly referred to as memory foam. Developed by NASA; memory foam is denser than normal foam and has body weight and temperature responsive properties. This means pressure points, like hips and shoulders, are minimised and your spine is held in perfect alignment whatever your sleeping position. This incredibly comfortable non-turn mattress is even fitted with air vents for a cool sleep.
Please note as this is a memory foam mattress, you may expect a slight odour within the first week of use. This is due to the fire retardant spray used on the memory foam.
