Black Diamond Collection

The Black Diamond Collection, described by Diamond Mattress as its newest collection, has only one series, Grandeur, with three firmness levels: Grandeur Luxury Medium, Grandeur Luxury Plush, and Grandeur Luxury Firm. These can be best described as hybrid mattresses. The support cores are foam-encased pocket coil innersprings. Above these coils are layers of comfort materials, including natural latex and Cross Flow Foam, and beneath is the base pad of high density orthopedic foam. All the foams are DM's Eco-Flex, meaning they are plant-based.

The three Grandeur models in the Black Diamond Collection have similar construction and the same height. Without further details, it appears the firmness levels are determined by the firmness and/or relative thickness of various components. Grandeur Luxury Plush is Plush with a firmness rating of 3. Grandeur Luxury Medium, at 5, is on the firm side of Medium. And at 8, Grandeur Luxury Firm is Firm.

The innerspring is composed of Diamond Mattress's 9-Series individually wrapped pocket coils. These coils isolate motion, so that one sleeping partner's movements do not disturb the other partner. They also relieve pressure and provide spinal support by conforming to body contours to evenly distribute the support. On their site, Diamond Mattress explains the differences between pocket coils and Bonnell coils.

Nested%20Coil

These pocket coils are nested. They are arranged in a hexagonal pattern rather than a square grid. This means more coils in the same area for a greater coil count with the same size coils with more even support. It also means a more stable coil array.

The pocket coil innerspring of the Grandeur is encased with foam. This protects the coils and holds them in place. It also serves as edge support. Along with the foam encasement is the Tri-Zoned foam lumbar support pad across the top of the coils in the center of the mattress. An Eco-Flex foam mattress pad under the coils supports the coils and acts as a shock absorber.

latex(2)

The principal cushion layer of Black Diamond mattresses is natural Talalay latex. This latex is made from rubber tree sap. It is perforated horizontally for ventilation. Used for its resilience and durability, latex is naturally anti-microbial, mold-resitant, and hypoallergenic.

The Cross Flow Foam is structured to facilitate the circulation of air through the mattress. The online descriptions do not specify where this layer is, above or below the latex. Like the other Diamond Mattress foams, it uses natural plant oils.

One retailer names CoolTouch gel memory foam as a component of the Black Diamond Grandeur mattresses, but this is not borne out in Diamond Mattress's descriptions or by other retailers.

Black Diamond Grandeur mattresses are covered with four-way stretch knit rayon. This cover is breathable and conformable. The type of fire barrier is not named.

The choices of foundations are between the Diamond Mattress fixed base of hardwood upholstered to match the mattress, and an adjustable base. DM sells two adjustable beds made by Ergomoation: Refuge Adjustable Lifestyle Base and Active Adjustable Lifestyle Base. The Grandeur is available through several retailers across the country.

Black Diamond Grandeur matttresses are covered by Diamond Mattress's 20-year limited warranty.
