A Quality Firm Mattress

by David Higgins

Offering layers of cooling technology and a targeted coil support system, the Simmons Beautyrest Cayman Extra Firm includes some top notch components. This mattress is a great choice for firm mattress lovers looking for a sustainable and reliable option.

A True Extra Firm

At a 2 out of 10 on the comfort scale, this is truly a firm bed. Layers of AirCool and Comfort foam add just enough softness to make it softer than sleeping on a carpeted floor and offer pressure relief to eliminate pain in your body's pressure points. A layer of memory foam offers some conforming comfort to add back support.

Targeted Coils

The innovative coil system offers dual coil support concentrated at the middle of the mattress to offer extra support where we need it most. The pocketed coil system allows for even more targeted support while at the same time helps reduce motion transfer between partners.

Natural Cooling Properties

Multiple components in this mattress contribute to an overall cooler and more regulated sleep so that you can fall asleep easier and reach deep REM sleep. Tencel yarn used in the mattress quilt naturally wicks away moisture for cooler sleep. The channeled design of the AirCool foam allows for great airflow, and properties of the charcoal used in the memory foam provide natural cooling.

Edge Support For Consistent Comfort

The BeautyEdge foam Encasement offers a border around the perimeter for a durable edge and consistent comfort anywhere on the mattress surface.

Sustainability In The Quilt

Made in partnership with Seaqual, this mattress includes a comfortable quilt made from plastic bottles that have been removed from the oceans. Each queen sized mattress gives new life to the equivalent of 25 discarded plastic bottles, working towards a greener tomorrow.

Is The Beautyrest Harmony Cayman Extra Firm Right For You?

The Beautyrest Harmony Cayman hits a great balance between quality construction and affordability. If you like a very firm feel, you won't be disappointed. This offers great sleep for stomach and back sleepers looking for firm support.
