Abstract
A pocketed spring assembly comprises a plurality of parallel strings of springs held together with tabs. Longitudinal seams joining overlapping tabs extend generally the same direction as the strings of springs. Pockets are formed along a string of springs by aligned separating seams. At least one spring is positioned in each pocket. Each separating seam joins opposed plies of the string and keeps the spring in its pocket. Ends of aligned separating seams are spaced from each other, thereby improving airflow between pockets.
