Abstract
In the disclosed assembly of pocketed springs, adjacent strips of the pocketed springs are joined together by connecting the pocket material of adjacent strips together between two consecutive springs of the two strips. Each interior strip of springs in the assembly is connected alternately to the adjacent strip on either sides, and in the preferred arrangement depicted in the drawings, the connections of each such strip to its adjacent strip on either side are made at intervals of two springs, and near both ends of the springs.
