Designed with comfort & hygiene in mind, the Cool Blue Memory Coil combines traditional Bonnell springs with the heat reduction properties of Cool Blue memory foam. Its advanced Cool Blue layer has been developed to offer the same feel & pressure relieving properties as equivalent memory foam, but without the associated heat discomfort. Cool Blue also features ultra-fresh anti-microbial, anti-bacterial & dust mite protection, plus excellent breathable properties for the ultimate in mattress hygiene. At the core of the mattress is a strong open coil interior that consists of hourglass shaped springs, set in rows running from head to toe & connected into one single unit by a spiral wire, known as a helical wire. As its one-sided, it only requires rotating from head to toe. For easy transportation, it will be delivered to you vacuum packed in a roll & is an ideal solution where access is limited.
