Beautyrest Harmony Lux Carbon 1000 Extra Firm Mattress Review

Updated November 3, 2022

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:

Comfort Scale Rating

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.

Pressure Test Results

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.
