Abstract:
Disclosed is a mutual support type pocketed spring bed core (1), comprising a plurality of rows of pocketed spring strings (11) bonded with one another, wherein each of the pocketed spring strings (11) comprises a plurality of individual springs (111) connected at intervals, and a cloth-like material (112) for packaging these individual springs; and all or some of the individual springs (111) in the pocketed spring strings (11) are packaged in the cloth-like material (112) in an arcuate manner. The arcuate individual pocketed springs (111) are arranged in consecutive "()" shapes and are close to each other. Springs mutually support each other, thus improving the stability of a bed core structure. Moreover, the bed core of such a structure can effectively reduce the number of springs in use and reduce the manufacturing cost thereof.
