Since the Memory on Top 800 is double-sided (Memory Foam side and Waterfoam side), is it suitable for every season?

Yes. Its dual-comfort construction and breathable materials provide outstanding sleeping comfort throughout the year. The Memory Foam side offers a softer, more body-contouring feel, while the Waterfoam side provides firmer, fresher support during warmer months. The 800 individually pocketed springs promote continuous airflow throughout the mattress, while the breathable 3D AIR PLUS border helps release excess heat and moisture, keeping the sleeping surface cool, dry and comfortable in every season.
