Updated March 14, 2022

Diamond 2000 Medium Pillow Top Mattress

The Harmony Lux Diamond 2000 Medium Pillow Top Mattress is a medium-feeling bed with a pillow top in the Beautyrest Harmony Lux collection. It's part of the Diamond Series, which is the higher end of Harmony Lux, and this model earned the #9 spot on our Top Ten Beautyrest Mattresses of 2022 list. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Lux Diamond 2000 Medium Pillow Top mattress is a medium-feeling pillowtop bed; we rate it a 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). It's a fairly neutral feel that most people will find comfortable. If you have a partner who likes a different comfort level than you, something like this would work well as a compromise. The pillow top will make it a little softer than a true medium.

Overview of the Diamond 2000 Medium Pillowtop

Here’s our quick video review of the Diamond 2000 Medium Pillow Top mattress which highlights the features, benefits, and our impression of the bed.

Conclusion

The Harmony Lux Diamond 2000 Medium Pillow Top mattress is a medium-feeling pillow top bed that's part of the Beautyrest Harmony Lux collection. It's one of five Harmony Lux Diamond Series models. There is also the Carbon Series, which is a step down from the Diamond Series but with many of the same features. This mattress is sold by online retailers as the HLD 2000 Medium Pillow Top.

It's a good mattress for just about anyone because it has a neutral comfort feel and I'd expect it to perform well for pressure relief and back support. There's plenty of pressure-relieving foams that are of premium quality. The support system is a great one, with pocketed coils for precise support, and a design that adds support to the center third for the lower back. It'll also appeal to those who are eco-conscious, as Simmons partnered with SEAQUAL for the Harmony Lux Collection. They use reclaimed plastics that were originally ocean debris and repurpose them to provide cooling in the quilt top. 

I'm looking forward to receiving this mattress to our facility soon, so we can test it ourselves and provide more details on it.
