Abstract
A bedding mattress, including a spring assembly having top and bottom parallel surfaces, padding over the top and bottom surfaces, and an upholstered covering completely encasing said spring assembly and padding. The spring assembly comprises multiple parallel rows of coil springs, each row of which is formed from a single continuous length of wire with each row containing a plurality of coils interconnected by connector segments. The rows of coils are interconnected by helical springs extending parallel to the rows and alternately wound around endmost turns of coils in a pair of adjacent rows of coils. The connector segment which interconnects the coils of each row comprises a generally diagonally extending connector bar having parallel end portions connected at the center by an offset section, which offset section is formed by rotation of the offset section relative to the end portions of the connector bar while the end portions of the connector bar are restrained against rotation.
