Abstract: A furniture elastic webbing is provided for use on sofa frames or the like to support seat and back cushions. The elastic webbing has a unique structure which provides controlled longitudinal stretch to support heavy loads such as the body weight of several adults simultaneously. The elastic webbing is warp knit by conventional methods with an inlaid, strong, durable control yarn generally walewise along each elastomeric yarn therein.

Abstract: Multiple wale lapping stitch loop chains are knit of additional yarn and extend over at least a pair of adjacent wales along at least one selvage edge of the elastic tape to prevent ravelling of the edge of the tape. The knitted elastic tape also includes a plurality of stitch loop chains knit of stretchable yarn and forming adjacent wales extending longitudinally of the tape and successive courses extending from one side of the tape to the other. An elastomeric yarn is inlaid in and extends along selected ones of the plurality of stitch loop chains and filling yarn extends back and forth across the tape so that the tape is stretchable in the lengthwise direction but substantially unstretchable in the widthwise direction.
