The Diamond Dream Collection Grand Plush Euro Top Discontinued Clearance Mattress is a plush innerspring 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 16", 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.
A foam-encased perimeter lets you use the full sleep surface — and sit on the edge to dress.
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.

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.
