The Main Harmony Lux Hybrid Trilliant Ultra Plush Features in Detail

Read about some of the layers inside the Trilliant Ultra Plush mattress to get an idea of what this mattress will feel like. For a full list of the materials, check out the specifications chart at the end of the review.

1. 1. InfiniCool Max

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

   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.

   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.
