The mattress's inner core is made of a medium-firm spring that distributes support throughout the night. A high-density (HD) insulator pad and breathable smart fibre comfort layers are placed on top of the spring to prevent spring feel. The breathable smart fibre comfort layers feature an open cell structure, which permits the free movement of air through the mattress and provides significant support for developing bones and muscles. The free movement of air helps to regulate body temperature and create a comfortable sleeping environment by preventing moisture buildup
