Description
Beautyrest® Harmony features new innovations in support, comfort, and cooling working together in harmony to unlock your best sleep. First, we’ve developed a Targeted Support System™ powered by T1 Pocketed Coil® Technology designed to offer additional support where your body needs it most. The T1 Pocketed Coil is placed within the center of the mattress to power the new support system. This patented, dual-stage coil design was invented by Beautyrest® and provides additional support under heavier compression. In addition, we’ve introduced new comfort technologies, including a premium memory foam infused with charcoal that provides natural cooling and pressure relief. Choose from breathable and eco-friendly TENCEL® fabric, or step-up to enhanced cooling with cool-to-the-touch technology within our Emerald Bay Series.
Beautyrest® has also expanded our partnership with SEAQUAL™ to offer their unique sustainable fabric technologies within each Beautyrest® Harmony mattress. Seaqual is a leader in ocean plastic recovery and upcycling efforts, and together this partnership will help promote cleaner oceans with every mattress sold.

Quality Meets Firmness
by David HigginsThe Simmons Beautyrest Harmony Cayman Extra Firm King Mattress is one of our firmest models, featuring our most advanced technology and support. With targeted coils, cutting-edge Comfort foam, and edge-to-edge durability, this sustainable model is an excellent choice for back and stomach sleepers craving that firmer feel.
The Firmest Firm
For those who want that carpeted floor feel, the Harmony Cayman scores a 2 out of 10 on our comfort scale. One of the firmest mattresses on the market, you’ll discover conforming comfort and enhanced back support with AirCool and Comfort foam. Layers of this advanced memory foam target your body’s pressure points to deliver the ultimate sleep experience.
An Innovative Coil SystemAn upgrade from traditional coils, our coils move independently from one another, concentrating support directly toward the middle of your mattress. By responding to your body as it moves, it conforms to your curves and targets support directly where you need it the most, all while reducing motion transfer.
Natural Cooling All NightAre you a warmer sleeper? Worry no longer with sustainable features that help regulate sleep all through the night. Tencel yarn is built directly into the quilt, helping to wick away moisture while you rest, even during scorching nights. AirCool foam features an advanced design that enhances airlflow, with charcoal incused into the foam to promote all-natural cooling.
Durable Edges All AroundWith a BeautyEdge foam Encasement surrounding your mattress, you’ll gain more durable edges that enable you to sleep anywhere on the surface with equal levels of comfort.
Built-In SustainabilityA partnership with Seaqual means makes this mattress more sustainable that its competitors. Designed with plastic bottles recovered from oceans around the world, you’ll contribute to a greener world.

Beautyrest Harmony Cayman Series Extra Firm Tight Top is a plateau of comfort. This has literally been the best sleep of my life! No lumps, with the perfect amount of firmness, I sleep throughout the night and don’t wake up with aches or pains. I look forward to purchasing my son’s their own as well. I definitely recommend!
