A protector keeps the warranty valid from night one — and it all rides along with your white-glove delivery, no extra trip.
The Diamond Dreamstage 2.0 Collection Clarity Plush Hybrid Cool Copper Gel Memory Foam Mattress is a plush pocketed-coil hybrid mattress built for side sleepers and combination sleepers. Diamond Mattress is family-owned and California-built — every model is hand-assembled in Chino with CertiPUR-US foams and OEKO-TEX natural fibers. At 14", it sits in the premium profile range — generous enough for adjustable bases yet still easy to sheet.
Hand-assembled in California with domestic steel coils and CertiPUR-US foams.
Individually wrapped coils flex independently for support that responds to your body, not the other way around.
A breathable quilt and gel-infused top draws heat away so you don't wake up hot.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.
A 3/10 firmness, soft enough to cradle hips and shoulders. Best for side sleepers under 200 lb.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
The Clarity Plush Hybrid combines the collection's cool copper gel memory foam with Diamond's own pocketed coil core, a 14-inch hybrid mattress that adds coil airflow, bounce, and edge support to the copper foam's cooling and pressure relief. Diamond builds its coils in-house in Southern California.
Side sleepers who want plush copper-cooled comfort but found all-foam beds too still or too warm should try this hybrid: the coil core breathes, responds, and supports the mattress edge for sitting and sleeping. It's the plushest way into the Clarity hybrid family.
Diamond Dreamstage 2.0 Collection Clarity Plush Hybrid Cool Copper Gel Memory Foam 14" Mattress is available in Twin, Twin XL, Full, Queen, King, CA King. White Glove delivery is free in Los Angeles on orders over $499.
Diamond Mattress is a 4th-generation family-owned company that has been handcrafting mattresses in Southern California since 1946. Founded by the Pennington family in Compton, California (now headquartered in Rancho Dominguez), Diamond is one of the few mattress manufacturers in America that is fully vertically integrated. They make their own pocketed coils, process their own memory foams, and cut and sew their own fabrics, all under one roof. This level of control over every component means Diamond can maintain strict quality standards that outsourced manufacturers cannot match. Every Diamond mattress is CertiPUR-US certified, GREENGUARD Gold certified for low chemical emissions, OEKO-TEX tested for harmful substances, and ECO INSTITUT certified for environmental safety. Diamond also uses REPREVE recycled fibers in select products, demonstrating their commitment to sustainable manufacturing practices.
