Abstract (en)
[origin: CA3071041A1] Disclosed is a pocket spring core comprising a plurality of springs (4, 5), a number of which lie in a row one behind the other in respective flexible pockets, preferably consisting of a textile material, forming a bank of springs (1), and a number of adjacent banks of springs (1), which together form a supporting surface, are interconnected. The springs (4, 5) of at least one region of the supporting surface have different springing characteristics from the springs (4, 5) of the neighbouring regions. Said pocket spring core is designed such that at least one part of the individual banks of springs (1) consists of bank portions (2, 3) with differing springing characteristics, the pocketed springs (4, 5) of each bank portion (2, 3) are identical, at least some of the neighbouring bank portions (2, 3) of adjacent banks of springs (1) are of different lengths and the neighbouring bank portions (2, 3) of adjacent banks of springs (1) are interconnected.
