Read the full termsThe Diamond Dreamstage 2.0 Collection Clarity Firm Cool Copper Gel Memory Foam 13" Mattress combines copper memory foam with a firm, all-foam support system in a 13-inch profile. It is the Clarity to compare when you like foam contouring and prefer a firmer overall surface.
A firm memory-foam mattress can still contour as you settle. Try this Clarity if you want that cushioning but do not enjoy a deeply plush feel. Turn onto your usual sleeping side and check shoulder comfort as carefully as the support you feel on your back.
The copper is part of the memory-foam formulation. It does not make a thick mattress automatically cooler, firmer or more supportive for every sleeper.
Add the 13-inch mattress to your frame and foundation measurements. The total determines sitting height; the mattress thickness alone does not. 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.
Use the size selector for current options, pricing and availability. Check Los Angeles delivery and setup options, or contact an LA Mattress showroom for help comparing Clarity Firm All-Foam with other feels. Compare more memory foam mattresses if you are still building your shortlist.

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.
