12-Inch Hybrid Queen Mattress | Cooling Gel Memory Foam & Pocket Springs | Medium Firm
Experience hotel-level luxury sleep with this 12-inch hybrid queen mattress. Engineered with a 9-layer ergonomic system combining copper-infused cooling gel memory foam and independent pocket springs, it delivers the perfect balance of pressure relief, spinal alignment, and temperature regulation — all in a convenient mattress-in-a-box format.
Key Features
- 9-Layer Ergonomic Design: Open-cell memory foam combined with high-density base foam prevents uncomfortable sinking while supporting lumbar and shoulder zones for side, back, and stomach sleepers.
- Advanced Cooling Technology: Copper-infused foam and a 4D knitted breathable cover actively dissipate body heat. Breathable spring channels keep you sleeping cooler than all-foam alternatives.
- Zero Motion Transfer: Independent pocket springs act as individual shock absorbers, minimizing motion transfer — ideal for couples or light sleepers.
- Reinforced Edge Support: Heavy-duty perimeter construction prevents sagging and roll-off, maximizing usable sleep surface and supporting up to 1,000 lbs without losing structural integrity.
- Orthopedic Back Support: Targeted lumbar reinforcement reduces lower back strain and morning stiffness. Adaptive comfort layers respond instantly to body pressure for improved posture.
- Safe & Certified Materials: 100% fiberglass-free and CertiPUR-US certified foam. Delivered compressed in a box — simply unbox and allow 48–72 hours for full expansion.
- Medium Firm Comfort: Maintains a stable medium-firm feel that prevents excessive sinking while contouring naturally to hips and shoulders.
