A method of making a mattress comprises arranging integral pocketed resilient elements in clusters 240. Each resilient element in a cluster is attached to at least one other integral resilient element and the clusters 240 define interstices where an independent resilient element 260 is to be inserted. To insert the independent spring 260, an inserter device 270 is placed vertically above the interstice. The inserter 270 comprises a hollow inserter tube 270a with a frusto-conical funnel portion 270b at its upper end, and an inner guide member 270c, a dome-shaped or conical leading end 270d projecting slightly beyond the end of the tube 270a. The tube 270a and guide member 270c are coaxial. To insert the independent spring into the cluster, the inserter 270 is inserted into the interstice with the dome-shaped leading end 270d helping to ease past the coils of adjacent springs in the cluster 240. The guide member 270c can be removed and the independent coil spring 260 can be inserted to the funnel portion 270b.

A string comprises springs 1100 (one is shown in broken lines) encased within pockets formed between leaves / plies / positions 1200 of pocketing material joined together between the springs at positions P, and at edges E and top seam S The joining of the leaves 1200 is done by ultrasonic welding.
