Since the Memory on Top 1600 is double-sided (Memory Foam side and Waterfoam side), is it suitable for every season?

Yes. The combination of high-porosity Memory Foam, 1600 individually pocketed springs and highly breathable materials promotes continuous airflow throughout the mattress. This helps maintain a cooler, drier and healthier sleeping environment all year round. The Memory Foam side delivers a softer, more body-contouring feel, while the Waterfoam side provides firmer, fresher support during warmer months.
