The Callum Firm by Englander is built for sleepers who want a clean, cool, and supportive sleep surface. It starts with a Premium Cooling Cover that’s soft to the touch and helps maintain a dry, temperature-regulated environment. Underneath, copper, graphite, and silver-infused memory foam promotes freshness with natural antibacterial and odor-resistant properties—while providing conforming comfort. A layer of firm foam resists body impressions and delivers the solid support preferred by back and stomach sleepers.

The mattress also features 5-Zoned Silhouette Foam, which offers targeted pressure relief and breathability across your body’s most sensitive areas. At the base, the 884 Edge Zoned Pocketed Coil Support System provides zoned alignment and reinforced edge support while reducing partner disturbance. With a 14-inch profile, adjustable-base compatibility, and a 10-year non-prorated warranty, the Callum Firm offers a high-performance sleep experience built for comfort, hygiene, and long-term durability.
