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. Zip-on/off for easy cleaning. Cool to the touch immediately.
Ice Flex Cooling Bands
Advanced mineral technology draws excess body heat away for 12+ hours. The signature cooling tech of the Black Diamond Collection.
Cool Titanium Memory Foam
Titanium-infused memory foam in a medium density for balanced contouring. Provides pressure relief without the deep sink of softer foams.
7-Series Wrapped Coil System
Individually wrapped coils with zoned support. Motion isolation, airflow, and edge-to-edge comfort.
Foam Encasement Edge Support
High-density foam perimeter for firm edge support and full surface usability.
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.

Combination Sleepers
Medium comfort works for back, side, and stomach positions. The hybrid coil system responds quickly to position changes, and the cooling technology works regardless of how you sleep.
Hot Sleepers Who Want Medium
CoolTouch cover, Ice Flex Cooling Bands, and Cool Titanium Memory Foam deliver 12+ hours of active temperature regulation in a versatile medium comfort level.
Couples
Medium is the universal compromise firmness. The 7-Series coil system isolates motion. The Ice Flex cooling prevents the heat buildup that occurs when two sleepers share a bed.
Side/Back Combo Sleepers
Medium provides enough cushioning for side sleeping and enough support for back sleeping. The titanium foam contours to your body without the deep sinking of softer memory foams.
