The Hilton Dual mattress is a double sided mattress with a winter and a summer side. The summer side is designed to keep you cool with an open coil spring system and traditional fillings to prevent the mattress from overheating and allowing you to have a restful nights sleep. The winter side provides warmth with a layer of memory foam that will mould to your body and retain heat, with less airflow (both sides are labelled). The Hilton mattress is tufted so all the fillings are held together securely and it is finished with a soft stretch knit cover.
