The Harmony Emerald Bay Medium Mattress is a medium-feeling bed in the Beautyrest Harmony collection. It's one of three Emerald Bay models that are at the higher-end of the Harmony collection. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Emerald Bay Medium mattress is a medium-feeling bed; we've rated this model a 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). This model will appeal to most people because its comfort is right in the middle of our scale. Those that prefer a firmer or softer-feeling mattress would be better off choosing another Harmony model mattress.

Pressure Test Results

We will pressure test the Beautyrest Harmony Emerald Bay Medium 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.) 

I'd expect the Emerald Bay Medium to perform well for all body sizes and sleep positions. Medium comfort mattresses like this one tend to perform well at relieving pressure and aiding in proper spinal alignment. Until we do get our pressure test results you can consult the images below to see what the results can look like once they've been completed.

Conclusion

The Harmony Emerald Bay Medium Mattress is a medium-feeling bed that is a part of the Beautyrest Harmony collection of mattresses by Simmons.  It's one of ten Harmony Series models and is one of three Emerald Bay models that are at the top end of this collection. The other two Emerald Bay models are the Medium Pillow Top and the Ultra Plush Pillowtop.

I expect this bed to perform really well at relieving pressure for all sleep types. 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, with no roll-off feeling at the edge.

I'd recommend the Harmony Emerald Bay Medium to anyone who enjoys plush comfort and solid back support. That said, those that prefer a firmer or softer-feeling bed will probably not find this particular model very comfortable. There are other options in the Beautyrest Harmony collection that would suit those people much better. One of my favorite parts of this mattress collection is its 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)!
