A Bonnell Spring mattress is a good mattress for back pain because :
Hourglass shaped springs tie together to form a mat-like structure, creating a uniformly firm mattress.
Restolex uses 12 springs per square feet against the industry standard of 11. This ensures durability and a consistent comfort level over many years of use.
In both bonnell and pocket spring mattresses, the high tensile steel springs are enveloped in Open Cell Structure (OCS) enabled latex foam or memory foam to release heat, making sure you stay cool.
