Experience the future of sleep with the Cal King – Matrix Copper Hybrid Waterfall-Top 11″ Firm Feel. This mattress features a whimsical decorative flat top panel and a raised hexagonal black side border for a unique and stylish look. The performance heat and moisture-wicking top panel helps regulate body temperature for a more comfortable night’s sleep. The Copper Infused Memory foam is hypoallergenic, body contouring, and dissipates heat, while the eco-friendly CertiPur-certified comfort foams provide additional support. The Individually wrapped coil system has firmer coils on the perimeter for increased sleeping area and structural integrity. The center third of the mattress is slightly firmer to compensate for most of our body weight. Made to order in California and ships in 3-5 days.
