The Harmony firm mattress offers a multi-layered approach to comfort and support, starting with an anti-microbial silver fire barrier for safety and hygiene. It features a 2-inch gel-infused firm quilt and memory foam for a cooling effect and pressure relief, complemented by high-density support foam for durability. The core of the mattress is made up of 700 series calibrated edge pocketed coils, providing targeted support and reducing motion transfer. A final layer of high-density foam reinforces the mattress's structure, culminating in a substantial 14.5-inch profile designed for a firm, supportive sleep experience.
