Designed for those who want support and comfort, the Phoenix features medium springs and a soft and luxurious knitted stretch fabric cover. A 10mm memory foam layer is positioned below the outer cover and is designed to react to body heat and mould itself to your contours. Hypoallergenic fillings provide a healthy sleeping environment, whilst the traditional method of hand tufting ensures the layers are held in place. Rows of open coil springs make up the interior, with each row running from head to toe and connected to each other by spiral helical wires. One sided, its not required to be flipped over, but we recommend regular rotation for enhanced performance, support and comfort.
