The Sealy Crown Jewel Pocket Conform Extra Firm Mattress is designed for sleepers who demand maximum support, precision comfort, and premium craftsmanship. As part of Sealy’s flagship Crown Jewel range, this mattress combines advanced pocket spring technology with high-quality comfort layers to deliver a firm, stable, and highly supportive sleep experience.

At its core is Sealy’s Crown Jewel Pocket Spring System, where each spring operates independently to respond to your body’s unique shape and movement. This provides targeted support across the entire body, promotes proper spinal alignment, and helps reduce partner disturbance for a more undisturbed night’s sleep.

The Extra Firm comfort feel is ideal for those who prefer a solid, supportive surface with minimal sink. High-density comfort layers provide controlled pressure relief while maintaining a firm, consistent feel that supports the body evenly from head to toe.

The Conform design enhances the mattress’s ability to adapt to your body while maintaining its firm structure, ensuring consistent support where it is needed most.

For added durability and usability, the mattress features reinforced edge support, allowing you to utilise the full sleeping surface while maintaining stability and firmness right to the edge.
