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
A breathable, removable cover with cooling fibers woven into the fabric. Zip-on/off design for easy cleaning. Cool to the touch from the moment you lie down.
Ice Flex Cooling Bands
Diamond's signature cooling technology. Advanced mineral bands actively draw excess body heat away from the sleep surface for 12+ hours of temperature regulation. This is the key differentiator of the Black Diamond line.
Cool Titanium Memory Foam
High-density memory foam infused with titanium for enhanced heat conductivity and body-contouring support. Provides weightless pressure relief while moving heat away from the body.
7-Series Wrapped Coil System
Diamond's proprietary individually wrapped coil system with targeted support zones. Boosts airflow through the mattress core, provides motion isolation, and delivers edge-to-edge support.
Foam Encasement Edge Support
High-density foam border around the entire perimeter. Provides a firm seating edge and maximizes the usable sleep surface from edge to edge.
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.

View Plush HybridCool, firm hybrid support.
The Snowbird Firm is for sleepers who want a firm hybrid mattress with advanced cooling technology. If you sleep hot on memory foam, the Ice Flex cooling system changes the equation.
Back Sleepers Who Run Hot
The firm hybrid surface keeps the spine aligned while the CoolTouch cover and Ice Flex Cooling Bands actively regulate temperature. Firm support without overheating.
Hot Sleepers
The Black Diamond Snowbird is built around cooling. CoolTouch Ultra Cool Cover, Ice Flex Cooling Bands, and Cool Titanium Memory Foam work together for 12+ hours of temperature regulation. This is not passive cooling. It is active heat removal.
Couples
The 7-Series Wrapped Coil System provides excellent motion isolation. Each coil responds independently. Foam encasement provides edge-to-edge support so both sleepers get a full surface.
Active Sleepers
The hybrid construction is more responsive than all-foam. The coil system provides bounce and quick recovery when you change positions. Less of the slow-sinking feel of pure memory foam.
