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.
Copper-infused cooling foam.
The Black Diamond Clarity is engineered around cooling. breathable knit cover, copper cooling Cooling Bands, and copper-infused 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.
Copper 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.
Antimicrobial Protection
Copper is a natural antimicrobial 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.
Copper cooling at every layer.
Diamond manufactures their own foams and coils in their Southern California factory. The Clarity uses copper-infused gel memory foam for natural cooling and antimicrobial protection.
Breathable Knit Cover
A soft, breathable knit cover designed for airflow and comfort. Diamond cuts and sews their own covers in California.
Copper-Infused Cool Gel Memory Foam
Memory foam infused with copper particles for natural cooling and antimicrobial protection. Copper draws heat away from the body and inhibits bacterial growth for a cleaner, cooler sleep surface.
Comfort Transition Foam
A transition foam layer provides progressive support between the contouring copper foam above and the coil system below. Prevents bottoming out.
Pocketed Coil Support System
Diamond's proprietary individually wrapped pocketed coils provide zoned support, motion isolation, and enhanced airflow through the mattress core.
Foam Encasement Edge Support
High-density foam border provides edge-to-edge stability and maximizes usable sleep surface.
Six models: All-Foam or Hybrid, three firmness levels.
The Clarity 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 copper-infused cool gel memory foam.

Our kids want to sleep in our bed now because it’s comfier than theirs! Might have to get them one too.
I saved up for over a year to get this mattress. The salesman was super helpful and knowledgable. The delivery was on time fast and efficient . It is Fantastic. Love it!
I’ve tried everything from memory foam to spring beds, and this hybrid is just perfect. It feels cool and supportive without being stiff.
I noticed a difference the very first night. I fell asleep faster and stayed asleep longer.
We upgraded from a 10-year-old spring mattress, and the difference is unbelievable. I wish we’d done it sooner.
