Tommy Bahama Shellebrate Mattress

The Extra Firm rating indicates a very stable, supportive surface with minimal sinkage. It is designed for sleepers who prefer to feel like they are resting on top of the mattress rather than sinking into it, providing significant spinal alignment.

This mattress uses TheraCool Memory Touch gel and copper-infused foam to pull heat away from the body. These materials are paired with a breathable 4-way stretch cover that promotes airflow to prevent heat buildup throughout the night.

Beyond its cooling properties, copper is naturally antimicrobial. This helps keep the sleep surface cleaner by resisting the growth of bacteria and odors over time.

The hybrid design combines the pressure-relieving contour of memory foam with the responsive support of 854 individually wrapped coils. This provides a balance of comfort and stability, ensuring the mattress remains durable and supportive for years.

Because of its extra firm profile, this mattress is generally best suited for back and stomach sleepers who require a flat, supportive surface to keep their hips and spine properly aligned. Side sleepers may find it too firm and might prefer a mattress with more pressure-relieving give.

The 854 individually wrapped coils provide targeted support and help reduce motion transfer between partners. Because each coil moves independently, the mattress can contour to your body while maintaining the firm foundation necessary for long-term durability.
