13-inch California King Plush Mattress with Dual Cooling Technology & Reinforced Lumbar Support - Medium Firm Feel for Cool, Restful Sleep

Experience restorative sleep with this 13-inch hybrid mattress featuring intelligent cooling technology and targeted support. The dual-phase cooling system actively regulates temperature using PCM technology, while premium gel-infused memory foam contours to your body and dissipates heat. At the core, 1,000 individually wrapped steel coils adapt to your movements and minimize motion transfer, reinforced by a 360° perimeter edge for full sleep surface usability. An exclusive reinforced lumbar zone provides 25% extra support where needed most. Combining pressure-relieving foams with durable steel construction, this mattress delivers balanced firmness—neither too soft nor too rigid—for proper spinal alignment and years of reliable comfort. *Why choose this mattress?* Its scientific cooling approach prevents night sweats, the robust coil system extends longevity while preventing sagging, and the specialized lumbar design targets back pain without sacrificing plush comfort—making it ideal for hot sleepers, couples, and those needing firm orthopedic support.
