The Harmony Lux Carbon 1000 Extra Firm mattress is a very firm feeling bed in the Beautyrest Harmony Lux collection. It's part of the Carbon Series, which is less expensive than the other series in this collection, Diamond. It's sold by online retailers as the HLC 1000 Extra Firm. For further information on this bed, we go into detail in our review below:
The Harmony Lux Carbon 1000 Extra Firm mattress is an extra firm bed; we rate it a 2 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 firm mattress. If you feel that a softer 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.
Here's our expert review video which highlights the features, benefits, and our impression of the mattress.

We've pressure tested the Beautyrest Harmony Lux Carbon 1000 Extra Firm 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.)
From the results shown below, you can see that this firmer mattress is not recommended for petite or average-sized people. The firmness of this mattress will likely cause excessive pressure on your hips and shoulders leading to a disruptive night's sleep. As is the case with most firm mattresses, this bed performed fairly well for people with larger-sized bodies, scoring a 'Good' for both back sleepers and side sleepers.

The Harmony Lux Carbon 1000 Extra Firm mattress has a 10-year warranty against factory defects.
The Harmony Lux Carbon 1000 Extra Firm mattress is an extra-firm bed from Simmons' Harmony Lux Collection. 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. This bed is sold by online retailers under the name HLC 1000 Extra Firm.
It's a great option for anyone who likes a firm bed. It provides decent pressure relief, even with the firm feel, but only for people with larger bodies. It has high-quality foams and an individually wrapped coil system, so it'll contour well. It'll also give good back support, thanks to the alternating coil in the center third of the mattress. We'll test this out with our pressure testing as soon as we can get the beds to our facility, and then I'll provide more detail.
It'll only suit those who like a firm bed, but it's a good price for some really high-quality materials and features, so I'd only recommend the Carbon 1000 Extra Firm to those who prefer this comfort. It has great edge support that we see on other Beautyrest models, and the construction will minimize motion transfer, so I'd also recommend this as a good bed for couples (as long as they agree on a firm feel).
