The Diamond Dreamstage 2.0 Collection Clarity Medium Hybrid Cool Copper Gel Memory Foam Mattress is a medium pocketed-coil hybrid mattress built for combination sleepers and most body types. 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.
Each coil moves on its own, so a partner getting up doesn't roll you out of position.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.
A 5/10 firmness, soft enough to relieve pressure on shoulders and hips, firm enough to keep your spine in line. Most-recommended firmness for combination sleepers.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
The Clarity Medium Hybrid is a 12-inch hybrid mattress pairing cool copper gel memory foam comfort layers with Diamond's in-house pocketed coils. Copper infusion cools the surface; the individually wrapped coils add airflow underneath, targeted support, and a responsive feel foam alone can't match.
This is the balanced pick of the copper hybrids: medium feel for side, back, and combination sleepers, hybrid responsiveness for people who change positions at night, and dual-path cooling (copper above, coil airflow below) for warm sleepers and warm bedrooms alike.
Diamond Dreamstage 2.0 Collection Clarity Medium Hybrid Cool Copper Gel Memory Foam 14" Mattress is available in Twin, Twin XL, Full, Queen, King, CA King. Queen starts at $1,399. All sizes include free White Glove delivery in Los Angeles.
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.
