A mattress closing tape formed of a crochet-type warp knitted construction comprises a set of warp yarns knitted in parallel series of lengthwise-extending chain stitches, first and second base filling yarns inlaid widthwise in opposing relation to each other through the chain stitches of the warp yarns to form a base fabric layer, and third and fourth sets of multiple pattern filling yarns inlaid diagonally in opposing relation to one another beneath the underlaps of the warp yarns to form a diamond pattern layer.
