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.

Read the full termsThe Diamond Dreamstage 2.0 Collection Tranquility Firm Titanium Memory Foam Tight Top 16" Mattress combines a firm feel, titanium memory foam and a tight-top finish in a 16-inch mattress. It is a useful comparison if you want a substantial bed without choosing a plush euro-top feel.
The Firm model shows why a tall mattress is not automatically soft. Try its flatter top in your usual sleeping position, then compare the Medium euro top if you want a different surface impression. Pay attention to comfort at your shoulders as well as how your hips settle.
The 16-inch profile is the full mattress height. Extra height does not tell you whether the surface will feel plush or firm; compare the comfort version as well.
At 16 inches, the mattress already adds substantial height. A suitable low-profile foundation can be worth considering for a more accessible finished bed. Use our bed-height comparison to plan the mattress and foundation together. For an adjustable setup, confirm the exact mattress-and-base pairing before ordering.
