Beautyrest Harmony Lux Carbon 1000 Plush Mattress Review

Updated January 24, 2022

Carbon 1000 Plush Mattress

The Harmony Lux Carbon 1000 Plush Mattress is a soft-feeling bed in the Beautyrest Harmony Lux collection by Simmons. There are two series in Harmony Lux - the Carbon Series and Diamond Series. This bed is part of the Carbon Series, which is less expensive. It's sold by online retailers as the HLC 1000 Plush. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Lux Carbon 1000 Plush mattress is a soft-feeling bed; we rate it a 5.5 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 may be more of a fit for you than this model.

Conclusion

The Harmony Lux Carbon 1000 Plush Mattress is a plush-feeling bed that is a part of the Beautyrest Harmony Lux collection of mattresses by Simmons. It's one of five available Harmony Lux Carbon Series models. There's also the Diamond Series, consisting of the four higher-end models. Online retailers sell this bed under the name HLC 1000 Plush.

This bed has great qualities that lead me to expect a bed that performs well and lasts for a long time. The materials are premium, with foams that are guaranteed to provide lots of pressure relief. The support system is right between the Silver and Black systems, a T2 pocketed coil system. It has alternating coils in the center third that will give additional support to the lower back. So this mattress will be comfortable and supportive. 

It'll also work well for couples because it has edge support that will make the entire surface sleepable, which is important when sharing a queen. And the coils move independently, minimizing the amount of motion transfer, so your partner's movements won't disturb you.

I'd recommend this bed to anyone looking for a high-quality, soft innerspring mattress.
