This Reflex Foam Divan Bed contains an orthopaedic open coil spring unit which provides excellent levels of support, as well as comfort. It has layers of traditional hypo-allergenic fillings including reflex foam. The layer of reflex foam largely contributes to the firmness rating of the mattress while the other layers offer enhanced comfort and luxury. Reflex foam is made up of tiny holes that slightly adapt to your body shape but bounce back against you at the same time. The high-density foam is naturally hypoallergenic and durable. Flexible and responsive, the mattress provides healthy spine alignment and back support.
