  1. 1. InfiniCool Max

    The material in the quilt and the layers immediately underneath have cooling characteristics, preventing you from overheating throughout the night. 

  2. 2. Micro Diamond Memory Foam

    Provides exceptional pressure relief and comfort, preventing tossing and turning, so you can get deeper sleep. Diamond particles in the foam conduct heat away from the body.

  3. 3. AirCool HD Memory Foam

    This unique memory foam formula is conforming, but it also allows airflow and feels responsive, so you don't overheat or sink in too much.

  4. 3. T2 Pocketed Coil Technology

    The coils are individually wrapped, so they contour to the curves of your body providing precise support right where needed. 

Warranty

The Harmony Lux Hybrid Trilliant Ultra Plush mattress has a 10-year warranty against factory defects.

Conclusion

The Harmony Lux Hybrid Trilliant Ultra Plush mattress is a model from Beautyrest which features Seaqual technology for better sustainability. This hybrid mattress has cooling qualities, plenty of pressure-relieving foams, edge support, and more great features. Try the medium and firm versions of this collection if this mattress is too soft.

The SEAQUAL technology in the cover uses recycled plastic removed from the ocean to make the fabric, so it's a great feature. It's also pretty amazing that this mattress features memory foam with diamond particles that help keep you cooler.

The pocketed coil technology on this bed is definitely a plus, it's my preferred type of support system. Coils that move independently will make this bed great at reducing motion transfer, so you can sleep soundly even if you share the bed. The support will be gentle yet will provide spinal alignment. Paired with several layers of memory foam, you'll feel comfortably supported throughout the night.

If you want a super soft mattress with a nod to sustainability, the Trilliant Ultra Plush is a great choice. It's expensive, but you can count on it to provide lasting comfort for many years.
