Pocketed spring assembly

A bedding or seating product comprising:

• a pocketed spring assembly of approximately a uniform height, the pocketed spring assembly comprising a plurality of parallel strings of pocketed springs, each of said strings being joined to at least one adjacent string, each of the strings 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 and having first and second opposed plies of fabric on opposite sides of the springs, the fabric of said first and second plies being joined by transverse seams,
• wherein at least some of the pockets of some of the strings are different sizes when empty due to different linear distances between the longitudinal seams and aligned free edges of the pockets, the pockets being approximately the same height with springs therein due, at least in part, to different properties of the springs.

A pocketed spring assembly for a bedding or seating product, said pocketed spring assembly comprising:

• interior and exterior parallel strings of pocketed springs of approximately the same height, each of the strings being joined to at least one adjacent string, each of the strings 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 and having first and second opposed plies of fabric on opposite sides of the springs, the fabric of said first and second plies being joined by transverse seams,
• wherein at least some of the pockets of the interior strings have different sizes when empty due to different locations of the longitudinal seams of the pockets of the interior strings, the pockets of the interior strings being approximately the same height with springs therein but of different firmness due, at least in part, to different properties of the pocketed springs and wherein the pockets of the interior strings being approximately the same size with springs therein due, at least in part, to the fabric.

A pocketed spring assembly for a bedding or seating product, said pocketed spring assembly comprising:

• a plurality of parallel strings of springs, each of said strings being joined to at least one adjacent string, each of said strings 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 and having first and second opposed plies of fabric on opposite sides of the springs, the fabric of said first and second plies being joined by transverse seams;
• wherein at least some of the strings contain pockets of different sizes without springs therein due to the location of the longitudinal seams of the pockets, first springs being inside small pockets and second springs being inside large pockets, thereby stretching the fabric of the small pockets to create a string having a generally uniform height and pocketed springs of different firmness.

A string of pocketed springs for a pocketed spring assembly, said string of pocketed 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 and having first and second opposed plies of fabric on opposite sides of the springs, the fabric of said first and second plies being joined by transverse seams;
• wherein said string has outer pockets and inner pockets between the outer pockets, the outer pockets being smaller than the inner pockets without springs therein, the inner and outer pockets being approximately the same size with springs therein.

A string of pocketed springs for a pocketed spring assembly, said string of pocketed springs comprising:

• a plurality of interconnected pockets, each of the pockets containing at least one spring encased in fabric, the fabric of each pocket being joined to itself along a longitudinal seam, adjacent pockets being separated by transverse seams,
• wherein the string has outer pockets and inner pockets between the outer pockets, the outer pockets being smaller than the inner pockets of the interior strings without springs therein due to placement of the longitudinal seams, the inner and outer pockets of the interior strings being approximately the same size with springs therein.
