Abstract
A spring assembly is provided including a plurality of interconnected longitudinal blocks of pocketed coil springs. Each block includes a pair of interconnected strips of pocketed springs which are preferably arranged in a square array. Each pair of strips is tightly encased by a flexible cover. The covers are connected to each other along longitudinal hinge lines which allows the assembly to bend easily in at least one direction.
