Spinal Comfort Bella Series

The Bella Series mattresses are in the Spinal Comfort Collection made by Diamond Mattress. This series has three models: Bella Pillow Top (Plush - 4), Bella Euro Top (Medium - 6), and Bella Firm Tight Top (Firm - 9). Although Diamond Mattress lists the Bella Firm Tight Top as Firm, with a firmness of 9 on a 1-10 scale it qualifies for Ultra Firm.

Diamond Mattress says that Spinal Comfort is its "most diverse collection." All of the mattresses in this collection feature foam-encasement and a Tri-Zoned innerspring. Foam encasement gives perimeter support to the coils and edge support to the surface. Tri-zoning the coils with greater coil density in the center third is to provide more support for the lumbar region.

The Bella models use the Verti-Coil innerspring system made by Leggett & Platt. According to Diamond, Verti-Coil (a sub-type of offset coils) provides much better pressure relief than Bonnell coils. It also is better at reducing motion transfer.

The cushioning comfort layers of the Diamond Mattress Spinal Comfort Bella Series consist of Diamond's Eco-Flex, foams using plant-based oils in their manufacture. Though described as "luxurious", these foams are high density. This keeps the sleeper from sensing individual coils. The softer, higher models add softer foam to soften the overall feel without sacrificing orthopedic support. The heights of the Bella models are 11" for Firm Tight Top, 11.5" for Euro Top, and 14" for Pillow Top.

Beneath the Diamond Mattress Verti-Coil innerspring support core of the Spinal Comfort Bella mattresses is a protective pad made of orthopedic Eco-Flex plant-based based foam. This protects the coils. These mattresses also have a non-skid surface to keep the mattress from shifting and sheets from slipping out of place.

The covers of Bella mattresses are made of 4-way stretch knit, a soft fabric. This is resistant to allergens, such as dust mites. It is also breathable, helping keep the mattress cool.

The foundation for the Spinal Comfort Bella Series is made of sustainable hardwood and is upholstered to match the mattress. These mattresses are not compatible with adjustable beds.

Diamond Mattress has a 20-year warranty for its Spinal Comfort mattresses, including the Bella models.
