The Calma Hybrid+ Super King Mattress pairs natural fillings with modern hybrid engineering across a generous sleeping surface with room to stretch out. Its medium feel suits every sleeping position, so partners with different habits can both settle in comfortably. The bamboo quilted top layer is soft against skin, while natural latex and an AIREASE gel core provide buoyant support and help regulate temperature on both sides of the bed. Small Quantum springs respond to each vertebra individually, and a ProEdge foundation gives edge-to-edge support across the full width.
