The ChillFlex open coil mattress offers exceptional value and is expertly hand-made in the UK. Designed for a refreshing and comfortable sleep, it features a luxuriously soft, cool-touch top panel that enhances breathability and promotes a cooler sleeping surface. At its core, the mattress contains a 13.5-gauge patented Ultra Max diameter open coil Bonnell spring unit, which evenly distributes weight and pressure over a wider area, improving overall comfort and support. Additionally, a layer of high-quality open-cell Cool Blue memory foam adapts to the contours of your body, providing superior pressure relief and enhanced support for a truly restful night’s sleep.
