The Huron mattress sits at the heart of our Great Lakes collection, offering a perfectly balanced feel that’s not too soft and not too firm. It begins with our QuadCore® pocketed coil system with TrueEdge360™ support, featuring a double row of coils around the entire perimeter to deliver stable, edge-to-edge support across the full sleep surface. Above the innerspring, multiple layers of high-density support foam provide the foundation needed for proper alignment and long-term performance. A true inner panel separates the support system from the comfort layers, allowing each component to perform as intended over time. The comfort system pairs copper gel-infused latex with copper-infused memory foam to create a cool, pressure-relieving surface that gently conforms to the body, promoting deep, restorative sleep.
