Luxury Medium Firm 12" Queen Hybrid Mattress With Euro Top And Memory Foam offers a medium-firm sleeping surface that balances pressure relief and support. The Euro top and memory foam layer cradle shoulders and hips while a pocket spring core with metal coils provides responsive, targeted support and reduces motion transfer. This 12-inch, multi-media design features a polyester cover and layers of foam including pu and memory foam, and it performs well on a standard foundation or box spring to maintain consistent support night after night.
