Why Choose an Amerisleep California King Hybrid Mattress?
- Maximum Sleeping Space: A California King mattress offers the most length of any standard size, making it ideal for taller individuals and couples who want extra legroom. Measuring 72 inches wide by 84 inches long, it provides ample space to stretch out and sleep comfortably.
- Best of Both Worlds: Our hybrid design combines the pressure-relieving comfort of our plant-based Bio-Pur® memory foam with the responsive support of individually pocketed coils. This creates a unique balance of cushioning and bounce that's perfect for a wide range of sleepers.
- Enhanced Cooling: The open-cell structure of Bio-Pur® foam, combined with the airflow-promoting design of our pocketed coils, helps to dissipate heat and keep you cool throughout the night. Our AS6 Black Series takes cooling even further with its advanced CryoCool™ cover and TitanAir™ layer, as endorsed by Dr. Jordan Burns for promoting restful sleep and recovery.
- Superior Support: Our zoned coil systems provide targeted support to different areas of the body, ensuring proper spinal alignment and reducing pressure points. This is especially important for a larger mattress size like California King, where consistent support across the entire surface is crucial.
- Minimal Motion Transfer: Individually wrapped coils minimize motion transfer, so you can sleep soundly even if your partner tosses and turns.
- Long-Lasting Durability: We use only the highest quality materials, including durable coils and high-density foams, to ensure your California King hybrid mattress provides lasting comfort and support for years to come.


Innovation in Every Layer: The Technology Behind Our Cal King Hybrids
- Bio-Pur® Foam: Our plant-based, open-cell memory foam provides superior pressure relief and contouring compared to traditional memory foam. It’s also more breathable, helping to regulate temperature.
- Pocketed Coil Core: Individually wrapped coils adapt to your body’s movements, providing targeted support and minimizing motion transfer. The open design also promotes airflow.
- Zoned Support (AS3 Hybrid, AS5 Hybrid, AS6 Black Series): Firmer coils around the hips and back provide extra support where you need it most, while softer coils around the shoulders offer a gentler cradle.
- CryoCool™ Cover & TitanAir™ Layer (AS6 Black Series): These advanced cooling technologies, featured in our AS6 Black Series, provide exceptional temperature regulation for hot sleepers.
- Natural Materials (Organica & Organica Plush): Our Organica models feature natural Talalay latex, organic cotton, and wool for a luxurious, eco-friendly sleep experience.
