摘要： An inclined pocketed spring string (4) and a pocketed spring bed core (3). The inclined pocketed spring string (4) comprises a plurality of pocketed individual springs (1) connected at intervals. Each pocketed individual spring (1) comprises a fabric (11) and an individual spring (12) packaged in the fabric (11). The individual springs (12) in the pocketed spring string (4) are entirely or partially inclined in the fabrics (11) in an inclined manner. The inclined pocketed spring string (4) and the pocketed spring bed core (3) of the present invention, as compared with the pocketed spring bed core of the same size, can effectively decrease the number of springs used and reduce manufacturing costs.
