The Harmony Lux Carbon 1000 Medium mattress is a medium-feeling bed in the Beautyrest Harmony Lux collection by Simmons. It's part of the Carbon Series. This mattress earned the #7 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 Carbon 1000 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 bit firmer than the 'medium' title, it'll be very popular with people who like firm mattresses. Those that prefer a softer-feeling bed should consider a different Harmony Lux model.

Pressure Test Results

The results of our pressure test on the Beautyrest Harmony Lux Carbon 1000 Medium mattress are below. The testing is 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.) 

This mattress performed fairly well during pressure testing, earning two recommended scores and three good scores. Ont the other hand, you can see that side sleepers who have a larger-sized body would likely experience excessive pressure on their hips, shoulders, and back. Mattresses of this level of comfort often cause extra pressure on larger-sized bodies.

You can use this information to aid in determining if the HLC1000 Medium mattress is the right model for you.

Conclusion

The Harmony Lux Carbon 1000 Medium mattress is a firmer-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, which is higher-end and has four models. It's sold by online retailers as the HLC 1000 Medium.

This bed has a lot going for it, there are top-quality foams for pressure relief, which is aided by good back contouring provided by the individually wrapped coil system. The coil system also will do a good job of supporting, it has added support for the lower back (alternating coil in the center third). The independent movement of the coils also decreases motion transfer. That, along with the edge support, will make it a good bed for couples. Even more so, the firmer feeling will appeal to those who like a firm bed but will likely not appeal to those who like a really soft bed.

I'd recommend trying out the Carbon 1000 Medium, it'll work for just about anyone. The cherry on top is the partnership with SEAQUAL that has Simmons including reclaimed plastic taken out of the ocean in every Harmony Lux model to add a cooling effect.
