The Harmony Lux Diamond 2000 Plush Mattress is a soft-feeling bed in the Beautyrest Harmony Lux collection from Simmons. It's part of the Diamond Series, which is the higher-end level of this collection. This mattress is sold by online retailers as the HLD 2000 Plush. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Lux Diamond 2000 Plush mattress is a soft-feeling bed; we rate it a 6 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). This type of comfort is for those who know they prefer a very soft mattress. If you feel that a firmer bed might suit your needs better then there are a couple of other Harmony Lux models that could work better for you than this model.

(Learn how we test.) 

Below you can see the body-mapping images of our three models who laid on their backs and sides.

Conclusion

The Harmony Lux Diamond 2000 Plush mattress is a plush-feeling bed that's part of the Harmony Lux Collection of high-end mattresses from Simmons. It's one of four available Harmony Lux Diamond Series models. There's also the Carbon Series, which is the less expensive end of the line and has four models. Online retailers sell this bed as the HLD 2000 Plush.

I'd recommend this bed to anyone looking for a soft, high-quality mattress. It has some top-notch foams that will give good pressure relief. It also has a support system with alternating coils in the center third that provide really good support to the lower back. Combined with the BeautyEdge, you're looking at a mattress that will be comfortable and supportive from edge to edge. The motion transfer will be minimal, since the coils are individually wrapped, so it'll be a good option for couples, as they can move without disturbing each other. 

The pressure test results confirm that the HLD2000 Plush mattress is an excellent choice for all body sizes and sleep positions. Its ability to relieve pressure on your joints while also providing great back support makes this mattress one of the best options in the Harmony Lux collection!
