A pocket spring core as well as a method for producing a pocket spring core for use in the manufacture of mattresses or furniture upholstery. The pocket spring core has a plurality of springs, a number of which lie in a row one behind the other in respective flexible pockets, forming a bank of springs, and a number of adjacent banks of spring, which together form a supporting surface, are interconnected. The springs of at least one region of the supporting surface have different springing characteristics from the springs of the neighboring regions. At least one part of the individual banks of springs consists of bank portions with differing spring characteristics, the pocketed springs of each bank portion are identical, at least some of the neighboring portions of adjacent banks of springs are of different lengths and the neighboring portions of adjacent banks of springs are interconnected.

A spring module includes a spring and a spring bracket for accommodating the spring. The spring bracket may have a base, an end cover and a flexible connecting part connecting the base and the end cover. The spring may be fixed in the spring bracket with a predetermined initial pressure. The spring module may be used in a spring cushion for furniture.

A spring assembly is provided that includes a plurality of first strings of springs and a plurality of second strings of springs. Each of the first strings are joined to at least another one of the first strings or one of the second strings. Each of the first strings includes first and second plies of fabric that define a plurality of pockets formed along a length of the first string. The pockets are formed by vertical seams that join the plies. The vertical seams each include an upper slit that extends through a top surface of the first string and a lower slit that extends through a bottom surface of the first string. Each of the pockets have at least one spring positioned therein.

In order to manufacture an innerspring unit comprising pocketed springs and having an increased stability at its edge regions, in a first step, an innerspring main body comprising a plurality of first strings of pocketed springs is provided. In a subsequent second step, at least one second string of pocketed springs is attached to a lateral surface of the innerspring main body, so that the at least one second string of pocketed springs extends in a longitudinal direction of the innerspring main body. The springs of the at least one second string of pocketed springs have a spring characteristic or a spring geometry different from the springs of the plurality of first strings of the innerspring main body. The at least one second string of pocketed springs forms together with the innerspring main body the innerspring unit.
