California-made since 1946.
Diamond Mattress is a 4th-generation family-owned manufacturer based in Southern California. They are one of the few mattress companies in America that makes their own coils, processes their own foams, and sews their own covers — all under one roof.
Vertically Integrated Manufacturing
Diamond makes their own pocketed coils, processes their own memory foam, and cuts and sews their own fabrics in-house. Most mattress brands outsource these components. Diamond controls quality at every stage of production.
Certified Clean Materials
GREENGUARD Gold, OEKO-TEX, CertiPUR-US, and ECO INSTITUT certified. Diamond uses REPREVE recycled fibers in select models. Every material is tested for chemical safety and environmental impact.
4th Generation Family Ownership
The Pennington family has owned and operated Diamond Mattress since 1946. Fourth-generation president Shaun Pennington leads a company that has never been sold to a conglomerate or private equity firm.
20-Year Warranty + 120-Night Trial
Diamond offers one of the longest warranties in the industry. Sleep on it for 120 nights. If you do not love it after 30 days, exchange it for a different Diamond model at no additional cost.
Technogel cooling foam.
The Black Diamond Technogel Armonia is engineered around cooling. breathable knit cover, Technogel cooling Cooling Bands, and Technogel Memory Foam work in concert to actively remove body heat for 12+ hours. This is not passive cooling. It is active temperature regulation built into every layer. Available as a hybrid mattress with Diamond\'s 7-Series Wrapped Coil System.
Technogel Cooling Bands
Diamond's signature cooling technology. Advanced mineral bands actively draw excess body heat away from the sleep surface. Not a gel layer, not a phase-change cover. Active mineral-based heat removal that works for 12+ hours continuously.
Cool Gel Memory Foam
Gel-infused memory foam provides additional cooling beyond the copper infusion. The gel absorbs and distributes heat evenly across the sleep surface for consistent temperature regulation.
Cooling Performance
The Technogel pattern maximizes cooling gel distribution material. Infused throughout the foam, it actively inhibits bacteria, mold, and mildew growth. This keeps the mattress fresher and cleaner over its lifespan without chemical treatments.
Technogel cooling in every layer.
Diamond manufactures their own foams and coils in their Southern California factory. The Technogel Armonia uses Technogel gel memory foam for natural cooling and cooling performance.
Breathable Knit Cover
Soft, breathable knit cover designed for airflow. Diamond cuts and sews covers in their California factory.
Copper-Infused Cool Gel Memory Foam
Memory foam infused with copper for natural cooling and cooling performance. Gel swirl technology distributes cooling gel away and inhibits bacteria for a cleaner sleep surface.
Comfort Transition Foam
Progressive transition foam bridges the contouring Technogel foam with the support base below.
High-Density Support Foam Base
A dense support foam base provides the foundation for the all-foam construction. Durable and supportive without the bounce of coils.
Six models: All-Foam or Hybrid, three firmness levels.
The Technogel Armonia line offers each firmness in two constructions: All-Foam (13\") for deeper contouring, or Hybrid (14\") with pocketed coils for added support and airflow. All use Cool Technogel memory foam.

Hot Sleepers
Technogel is one of the most effective cooling materials in the mattress industry. The gel grid structure dissipates heat faster than memory foam, copper foam, or standard gel-infused foams.
Firm Comfort Seekers
The 11-inch firm profile provides flat, responsive support. Technogel contours to the body without the deep sinking of memory foam.
Premium Quality Seekers
At $4,099 Queen, the Armonia is Diamond’s most premium all-foam offering. Italian Technogel technology built in Diamond’s California factory.
Durability-Focused Buyers
Technogel maintains its properties significantly longer than memory foam. It does not develop body impressions as quickly and retains its cooling effectiveness over years of use.

What sleepers are saying.
5.0 out of 5 · 27 verified reviews
I am finally able to sleep comfortably on a mattress again!
Great for side and back sleepers both. It adjusts very well.
It�s comfy AND orthopedic.
I fall asleep faster and wake up way less during the night.
I�d recommend it to anyone who values quality sleep.
