Abstract
A pocket spring string, a pocket spring mattress core and a mattress. The pocket spring string includes: springs; cloth, which is folded and provided with welds to form multiple adjacent pockets, each pocket being provided with an opening, and the springs being received in the pockets respectively; and thread provided to stitch the openings so that the springs are packaged in the pockets in a compressed state. The pocket spring mattress core is formed by connection of the pocket spring strings, and the mattress includes a mattress cover and the pocket spring mattress core. Because the top and/or bottom of each pocket is provided with the opening which is stitched by the thread, when the thread is removed, the springs can be quickly separated from the pockets, so that the metal material and the cloth are separated without any special technical means.
