A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

A cover layer (23) of a fleece material for an innerspring unit (20) comprising a plurality of pocketed springs (29) is manufactured by supplying at least two longitudinal fleece webs (24, 25), which extend substantially parallel in a longitudinal direction and are spaced from one another, and repeatedly attaching a transverse fleece web (26, 27), which extends between the longitudinal fleece webs (24, 25) in a direction substantially perpendicular to the longitudinal direction, to the longitudinal fleece webs (24, 25). The transverse fleece web segments (26, 27) are attached to the longitudinal fleece webs (24, 25) such that they form together with the longitudinal fleece webs (24, 25) a framelike structure (21) serving as the cover layer (23).

A pure bamboo fiber mattress and a manufacturing method thereof are disclosed. The manufacturing method includes the following steps: trimming and cleaning bamboo; sawing; splitting; slicing the bamboo strips; knitting; softening; directional fiber opening; dry cleaning, drying and removing dust; stacking; sewing and packing. The pure bamboo fiber mattress includes a surface layer, a transition layer, a core layer, another transition layer and another surface layer that are arranged in sequence from top to bottom. The surface layer includes 3-5 layers of first bamboo mesh fabric laid one on top of another. The transition layer includes 3-8 layers of second bamboo mesh fabric laid one on top of another. The core layer includes 3-8 layers of third bamboo mesh fabric laid one on top of another. The first bamboo mesh fabric, the second bamboo mesh fabric and the third bamboo mesh fabric are made of bamboo fibers.
