Updated January 24, 2022

Diamond 2000 Medium Mattress

The Harmony Lux Diamond 2000 Medium mattress is a soft-feeling bed in the Beautyrest Harmony Lux collection of luxury mattresses with an eco-friendly twist. It's part of the Diamond Series, which is the higher-end of Harmony Lux. This bed is sold by online retailers as the HLD 2000 Medium. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Lux Diamond 2000 Medium mattress is a medium-feeling bed; we rate it a 3 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). It's a neutral comfort level that will work for a lot of people. It makes a good compromise for people who share a bed but not the same preferences.

Pressure Test Results

We will soon pressure test the Beautyrest Harmony Lux Diamond 2000 Medium mattress to see if the bed provides good support, pressure relief, and comfort for large, medium, and petite-sized people. Using models of each size we map their bodies while lying down on their side and back sleeping positions for a clear image of how well this mattress will perform for most people. (Learn how we test.) 

Although we don't have the results yet, I'd expect this bed to perform very well for pressure relief and support based on the findings from similar Beautyrest mattresses. The construction and materials that make up the Diamond 2000 Medium are of top quality.

Conclusion

The Harmony Lux Diamond 2000 Medium mattress is a medium-feeling bed that is a part of the Beautyrest Harmony Lux collection of mattresses by Simmons. It's one of four available Harmony Lux Diamond Series models. There's also the Carbon Series, which consists of five models that are less expensive than the Diamond Series but have most of the same features. This bed is sold by online retailers as the HLD 2000 Medium.

I'd expect this bed to perform very well when we do our pressure tests. It has some high-quality foams that will relieve pressure competently. And the T2 Pocketed Coil system will add to the contouring effects, supporting where most necessary. The back support will be sufficient as well, the center third is designed to add more support for the lower back without being too rigid. 

There are nice features, like edge support, cooling technology, and the fact that the mattress is adjustable base compatible. And this bed actually helps with removing plastic out of the ocean. The Harmony Lux Collection uses SEAQUAL's reclaimed plastic in every model to provide the cooling feature.

I'd recommend this bed to anyone who wants something higher-end that'll be comfortable and lasting. It'll work for just about anyone, with its neutral comfort feel and expected high performance. Couples who really want motion transfer reduction will find that in this bed.
