This Asia Coilsprung Divan Bed is a dual sided mattress with a summer side and a winter side. It has been specially designed to provide season specific comfort; the summer side helps to keep you cool with its bonnel open coil spring system and traditional fillings to prevent the mattress overheating and allowing you to have a restful sleep, and the winter side provides warmth with a memory foam layer so that you feel cosy and sleep soundly, protected from the cold winter weather. The mattress has differing labels and covers to differentiate between the two sides.
