Comfort Scale Rating

The Harmony Lux Hybrid Trilliant Medium mattress is a medium-soft feeling bed; we rate it a 6 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). This soft-neutral comfort will be great for most people, especially those who want something soft but not pillowy. For different comfort options, try the firm and plush versions of this collection.

The Main Harmony Lux Hybrid Trilliant Medium Features in Detail

Harmony Lux Hybrid Trilliant Medium Cutaway Image

  1. 1. InfiniCool Max

    This cooling system right at the top of the mattress feels cool to the touch and will keep you in deeper sleep by preventing overheating.

  2. 2. Micro Diamond Memory Foam

    Diamond particles in this foam draw heat away from the body. It's very pressure-relieving as well.

  3. 3. RapidCool Gel Memory Foam

  4. Cooling gel along with an open cell structure makes this foam effective at maintaining an ideal temperature.

  5. 3. T2 Pocketed Coil Technology

    The individually wrapped coils contour to your body and gently push back right where you need support. Expect minimal motion transfer and maximum supportive comfort out of this support system.

Warranty

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

Conclusion

The Harmony Lux Hybrid Trilliant Medium mattress from Beautyrest has tons of cooling materials, a pocketed coil system, and a foam encased edge. If the medium does not work, try the firm and plush versions of this collection.

It's compatible with any bed type, including adjustable frames. It also features SEAQUAL technology in the cover, so some of the material is made out of plastic debris found in the ocean. I have to mention the diamond particles found in the top layer of memory foam. They provide a cooling effect by drawing heat away from the body, which is pretty amazing.

With a neutrally soft comfort level, excellent premium features, and cooling technology to maintain a pleasing temperature, this bed has a lot going for it. 

I'd call the Trilliant Medium a crowd-pleaser! I recommend it to anyone interested in a hybrid mattress, as long as it's within your budget, as this mattress is one of the best on the market right now.
