Pressure Test Results

We've pressure tested the Beautyrest Harmony Lux Diamond 2000 Plush Pillow Top mattress to see if it'll provide good support, pressure relief, and comfort for large, medium, and petite-sized people. We used models of each body size to 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 three out of six 'recommended' scores for goor pressure relief and spinal alignment. The bed did, however, earn a 'not recommended' score for side sleepers who weigh between 134 and 218 lbs. The reason for this was the excessive amount of pressure that our model experienced on their shoulder which you can see shaded red on the images below. Overall, the HLC2000 Plush Pillowtop showed good pressure relief and back support for most people.

Conclusion

The Harmony Lux Diamond 2000 Plush Pillow Top Mattress is a medium-feeling pillow top bed that is a part of the Beautyrest Harmony Lux collection of mattresses by Simmons.  It's one of four Harmony Lux Diamond Series models. There's also the Carbon Series, which is the less expensive end of the collection and has five models. Online retailers sell this bed as the HLD 2000 Plush Pillow Top.

I expect this bed to perform really well for relieving pressure, as it has a neutral comfort level with some premium foams. The back support system is a good one too and will be very contouring while keeping the spine aligned. The center third has an alternating coil which will definitely boost up the support to the lower back, without being too stiff. This type of coil system, which has individually wrapped coils, is also good at minimizing motion transfer, so the beds in this collection will work well for couples. Adding to this is the edge support, so the entire surface of the mattress will be comfortable for sleeping on, no roll-off feeling at the edge.

I'd recommend the Harmony Lux Diamond 2000 Plush Pillow Top if you want a very soft luxury mattress. It'll be a very high-end mattress with some cool features. One of my favorite parts is their use of reclaimed plastics in every model to provide cooling near the surface, which helps you sleep comfortably and cleans up the ocean (they're partnered with SEAQUAL to do this)!
