Shire Memphis Memory Mattress in a Box - 6ft Super King Size; Designed to be supportive and comfortable, the Memphis features a robust open coil spring system and an advanced layer of cool blue memory foam. Cool blue memory offers the same feel and pressure relieving properties as equivalent memory foam, but without the associated heat discomfort. Its durable spring system is made up of rows of hourglass shaped open coils connected at the top and bottom by a spiral wire, known as a helical wire. The Memphis will be delivered vacuum packed in a roll and is designed to be one-sided, although we recommend regular rotation for long-lasting comfort.
