The Spring Air Contentment Firm Back Supporter mattress offers you a combination of exceptional back support and pressure-relieving comfort. The Back Supporter Spring Unit features individually wrapped coils that allows motion separation between you and your partner for undisturbed rest. This heavy duty Sampson dual-gauge design features firmer coils in the center for added support in the lumbar area. The 5 layer air suspension foam system includes cooling Gel Memory Foam to improve airflow and release trapped heat and Gel Infused Latex Foam for extra pressure relief and heat regulation. The Body Span Insulator distributes body weight through entire mattress and increases support by 25%

Both hybrid innerspring mattresses and regular innerspring mattresses have an open structure which prevents heat buildup, enabling them to sleep cooler than an all foam mattress.
