Pocketed spring assembly comprising strings of springs having Y-shaped seams

A posturized bedding or seating product comprising:

• a pocketed spring assembly comprising a plurality of parallel strings of springs joined to each other, each of the strings of springs comprising a plurality of interconnected pockets, each of the pockets containing at least one spring encased in fabric, the fabric being joined to itself along a longitudinal seam;
• wherein adjacent individually pocketed springs are separated from each other by a separating seam joining opposed first and second plies, each of the separating seams comprising first and second V-shaped end portions joined together by a linear portion, some of the strings of springs having a greater firmness than other strings of springs of the parallel strings of springs due, at least in part, to a difference in size of the V-shaped end portions, the pocketed spring assembly having different regions of different firmness, the separating seams of the strings of springs within each region being identical and different than the separating seams of the strings of springs of at least one other region.

A posturized pocketed spring assembly for use in a bedding or seating product, the pocketed spring assembly comprising:

• a plurality of strings of springs, each of said strings of springs comprising a piece of fabric joined to itself along a longitudinal seam and multiple spaced separating seams to define a plurality of pockets, each pocket containing at least one spring;
• wherein opposed plies of the fabric being joined together by the separating seams, each of the separating seams comprising a linear portion and first and second branch portions, each branch portion comprising two diverging branches extending outwardly from one end of the linear portion of the separating seam;
• the pocketed spring assembly having different regions of different firmness, the separating seam of the strings of springs within each region being identical and different than the separating seams of the strings of springs of at least one other region, the strings of springs of at least one region having a greater firmness than the strings of springs of at least one other region due, at least in part, to a difference in shape of the separating seams of the strings of springs.

A posturized pocketed spring assembly for use in a bedding or seating product, the pocketed spring assembly comprising:

• a plurality of strings of springs, each of said strings of springs comprising a piece of fabric joined to itself along a longitudinal seam and multiple spaced separating seams to define a plurality of pockets, each pocket containing at least one spring, each spring having upper and lower end turns and central convolutions between the end turns,
• wherein each of the separating seams comprises a linear portion and a pair of branch portions, each branch portion extending outwardly from the linear portion of the separating seam, said spring assembly being characterized, when a load is placed upon the spring assembly, by the ability of at least some of the central convolutions of the spring to move laterally in the pocket of fabric, some of the strings of springs having a greater firmness than other strings of springs of the parallel strings of springs due, at least in part, to a difference in shape of the branch portions of the separating seams.

A posturized pocketed spring assembly for use in a bedding or seating product, the pocketed spring assembly comprising:

• a plurality of strings of springs, each of said strings of springs comprising a plurality of interconnected pocketed springs, each spring of which is contained within a pocket of fabric, each spring having upper and lower end turns and central convolutions between the end turns, adjacent individually pocketed springs being separated from each other by at least one separating seam joining first and second plies on opposed sides of the string of springs, each of the separating seams comprising two Y-shaped seams joined together,
• said pocketed spring assembly being characterized, when a load is placed upon the pocketed spring assembly, by the ability of some of the central convolutions of the spring to move laterally in the pocket of fabric within which the spring is contained and return to their original position upon removal of the load, some of the strings of springs having a greater firmness than other strings of springs of the parallel strings of springs due, at least in part, to a difference in shape of the separating seams.
