Beautyrest Harmony Cayman Extra Firm Mattress Review

Updated November 3, 2022

Cayman Extra Firm Mattress

The Harmony Cayman Extra Firm Mattress is a very firm-feeling bed in the Beautyrest Harmony collection. This mattress is the firmest of the ten models in the Beautyrest Harmony collection, and it's one of five Cayman models within that collection. For further information on this bed, we go into detail in our review below:

Comfort Scale Rating

The Harmony Cayman Extra Firm mattress is a very firm-feeling bed that we rated a 2 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). People who really enjoy sleeping on a harder surface will enjoy this bed's comfort type. However, for those who think they'd need a more plush feel to their mattress this model will not suit your needs. 

Overview of the Cayman Extra Firm

Here’s our quick video review of the Cayman Extra Firm mattress which highlights the features, benefits, and our impression of the bed.

Pros & Cons

PROS CONS
  • Partnership with SEAQUAL to reduce debris in the ocean
  • Individually pocketed coils
  • Cooling technology
  • Beautyrest is a trusted brand
  • The very firm feel will only appeal to those who enjoy a very hard sleeping surface

Pressure Test Results

We will pressure test the Beautyrest Harmony Cayman 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.) 

I'd expect the Cayman Extra Firm to not perform well for most sleep positions and body types. Firmer mattresses tend to cause excess pressure on the hips and shoulders for side sleepers so this mattress will probably not perform very well. It's the people who really like sleeping on a super hard surface who would enjoy this type of comfort from their mattress. 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 Cayman Extra Firm Mattress is a very firm-feeling bed that is a part of the Beautyrest Harmony collection of mattresses by Simmons.  It's one of five Cayman models in the Harmony collection and is the firmest of all ten mattresses in that collection.

I expect this bed to not perform really well at relieving pressure at all. The back support system is a T1 coil system, which has individually wrapped coils. 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 only recommend the Harmony Cayman Extra Firm if you want a very firm mattress. That said, those that prefer a 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)!
