Features
The Beautyrest Black Series Three mattress integrates several technologies to provide a supportive and comfortable sleep environment:
- Triple-Stranded Pocketed Coil Technology: This system provides individualized support and minimizes motion transfer, allowing for undisturbed sleep.
- Enhanced Temperature Management: Cooling yarn and cashmere are woven into the mattress surface, combined with specialized vertical fibers, to help dissipate heat away from the body.
- Advanced Pressure Relief: A layer of SurfaceTouch Gel Memory Foam is quilted into the sleep surface for immediate pressure relief.
- Cooling Pressure Relief: Premium Micro Diamond Memory Foam, infused with diamond particles, assists in moving heat away from the body.
- Responsive Pressure Relief: Self-Response Latex contours to the body's unique pressure points while promoting airflow.
- Extra Firm Support: This mattress is designed for those who prefer a bed with minimal give, offering maximum stability and strong support, particularly suited for back and stomach sleepers.

Operating
Your Beautyrest Black Series Three Extra Firm Full Mattress is designed to provide a stable and supportive sleep surface. As an extra firm mattress, it offers minimal give, which is ideal for individuals who prefer a very solid feel and for back or stomach sleepers seeking robust spinal alignment.
Allow a brief period for your body to adjust to the new mattress, especially if transitioning from a different firmness level. The advanced materials and coil technology work together to provide consistent support and temperature regulation throughout the night.
Maintenance
Proper care and maintenance will help extend the lifespan and maintain the performance of your mattress:
- Mattress Protector: It is highly recommended to use a mattress protector to shield your mattress from stains and spills. This is crucial for maintaining the mattress's overall health and lifespan.
- Liquid Avoidance: Do not apply liquids directly to the mattress. Liquids can stain the fabric and potentially worsen soiled areas. Moisture or chemicals can also cause premature breakdown of the foam and damage the product.
- Cleaning Spills: In case of a spill, do not use liquid cleaners. Instead, apply baking soda to the soiled area. Allow it to stand for approximately 15 minutes, then vacuum it up. Repeat this process as needed. Ensure the product is aired out as much as possible after cleaning.
- Rotation: Periodically rotating your mattress (head to foot) can help promote even wear and extend its comfort life. Consult your warranty for specific rotation recommendations.
Troubleshooting
If you experience any issues with your Beautyrest Black Series Three mattress, consider the following:
- Comfort Adjustment: New mattresses, especially extra firm models, may require an adjustment period. Allow several weeks for your body to adapt to the new support system.
- Sagging or Indentations: Ensure your mattress is placed on a compatible and supportive base. An inadequate or old base can contribute to premature sagging. If significant indentations occur that are not related to normal body impressions, refer to the warranty information for potential claims.
- Noise: While pocketed coils are designed for minimal noise, ensure the mattress is properly seated on its base and that the base itself is stable.
