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.
Ice Flex cooling technology.
The Black Diamond Snowbird is engineered around cooling. CoolTouch cover, Ice Flex Cooling Bands, and Cool Titanium 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.
Ice Flex 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.
CoolTouch Ultra Cool Cover
Cooling fibers woven directly into the fabric create a surface that is cool to the touch immediately. Removable zip-on/off design for easy washing. The first layer of the Snowbird's multi-layer cooling system.
Cool Titanium Memory Foam
Memory foam infused with titanium for enhanced thermal conductivity. Titanium moves heat away from the body faster than standard gel-infused foams. Provides pressure relief without the heat penalty of traditional memory foam.
Cooling at every layer.
Every layer of the Snowbird is designed around cooling and support. Diamond manufactures their own coils and processes their own foams in their Southern California factory.
CoolTouch Ultra Cool Cover
Breathable, removable cover with cooling fibers. Critical on a plush mattress where heat buildup is common.
Ice Flex Cooling Bands
Advanced mineral technology actively removes excess heat for 12+ hours. Especially important on the Plush model where thicker foam layers naturally trap more heat.
Cool Titanium Memory Foam
Plush-density titanium-infused memory foam for deep body contouring and pressure relief. The titanium enhances heat conductivity, moving warmth away from the sleep surface.
7-Series Wrapped Coil System
The coil system prevents excessive sinking beneath the plush foam layers. Provides the support foundation that keeps the plush feel from bottoming out.
Foam Encasement Edge Support
Maintains edge stability despite the softer comfort layers above.
Three comfort levels, one cooling system.
Every Snowbird shares the same CoolTouch cover, Ice Flex Cooling Bands, Cool Titanium Memory Foam, and 7-Series Wrapped Coil System. The difference is how the foam layers are configured for firmness.

Currently ViewingPlush hybrid that sleeps cool.
The Snowbird Plush delivers deep cushioning with Diamond\'s Ice Flex cooling system. The plush memory foam mattress that does not overheat.
Side Sleepers Who Run Hot
Plush mattresses typically trap heat. The Snowbird Plush solves this with Ice Flex Cooling Bands and CoolTouch cover. Deep pressure relief at the shoulders and hips without overheating.
Hot Sleepers Who Want Soft
If you love plush comfort but hate sleeping hot, the Snowbird Plush is built specifically for you. 12+ hours of active cooling in a soft, body-contouring profile.
Pressure-Sensitive Sleepers
The plush Cool Titanium Memory Foam distributes body weight evenly. If you experience numbness or tingling on firmer surfaces, the Snowbird Plush provides relief without the heat penalty.
Couples Who Like Soft
The 7-Series coil system provides motion isolation beneath the plush foam layers. Two sleepers generate more heat together. Ice Flex cooling handles it.

I�ve tried so many mattresses, and this one finally gave me the comfort I�ve been missing.
This mattress feels like sleeping on a cloud. The plush hybrid design gives the perfect mix of softness and support. I wake up refreshed every day.
Took me a while to decide, but I�m so glad I chose this mattress. The comfort level is unmatched.
The build and stitching are top-notch.. Absolutely satisfied with my purchase.
