Abstract

A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising one piece of fabric folded into first and second opposed plies of fabric. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring and at least cushion pad is positioned in each outer pocket. The cushion pad may be individually pocketed. An upper end of each transverse seam may be below an upper surface of the string to partially separate adjacent outer pockets within a string.

First claim

What is claimed:

1. A bedding or seating product comprising:
a pocketed spring assembly;
an edge support extending along each of two opposing sides of the pocketed spring assembly, each edge support comprising a plurality of parallel edge strings of springs, each of said edge strings being joined to at least one adjacent edge string, each of said edge strings comprising a piece of fabric surrounding a plurality of pocketed springs and a plurality of cushion pads, first and second opposed plies of fabric being on opposite sides of the pocketed springs and cushion pads, a plurality of outer pockets formed along said string by a longitudinal seam and transverse seams joining said first and second plies, at least one pocketed spring and at least one cushion pad being in each of said outer pockets;
cushioning materials; and
a covering encasing said pocketed spring assembly and cushioning materials.

2. A bedding or seating product comprising:
a pocketed spring assembly;
an edge support extending along each of two opposing sides of the pocketed spring assembly, each edge support comprising a plurality of parallel edge strings of springs, each of said edge strings being joined to at least one adjacent edge string, each of said edge strings comprising a piece of fabric surrounding a plurality of pocketed springs and a plurality of cushion pads, first and second opposed plies of fabric being on opposite sides of the pocketed springs and cushion pads, a plurality of outer pockets formed along said string by a longitudinal seam and transverse seams joining said first and second plies, at least one pocketed spring and at least one cushion pad being in each of said outer pockets.

3. The product of claim 2 , wherein each of the cushion pads is individually pocketed.

4. The product of claim 2 , wherein the pocketed spring assembly comprises a plurality of parallel interior strings of springs, each of said interior strings being joined to at least one adjacent interior string, each of said interior strings comprising a piece of fabric surrounding a plurality of pocketed springs and a plurality of cushion pads, first and second opposed plies of fabric being on opposite sides of the pocketed springs and cushion pads, a plurality of outer pockets formed along said string by a longitudinal seam and transverse seams joining said first and second plies, at least one pocketed spring and at least one cushion pad being in each of said outer pockets.

5. The product of claim 2 , wherein said longitudinal seam of each of said edge strings is a side seam.

6. The product of claim 2 , wherein two cushion pads are in each of said outer pockets.

7. The product of claim 2 , wherein each edge support comprises two parallel strings of springs.

8. A bedding or seating product comprising:
a pocketed spring assembly;
an edge support extending around the perimeter of the pocketed spring assembly, the edge support comprising a plurality of perimeter strings of springs, each of the perimeter strings being joined to at least one adjacent perimeter string, each of the perimeter strings comprising a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing at least one inner pocketed spring and at least one cushion pad, the piece of 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 first and second plies being joined by transverse seams between adjacent inner pocketed springs.

9. The product of claim 8 , wherein two cushion pads are in each of said outer pockets.

10. The product of claim 9 , wherein said at least one inner pocketed spring is between the cushion pads.

11. The product of claim 8 , wherein the pocketed spring assembly comprises interior strings of springs.

12. The product of claim 8 , wherein each of the perimeter strings comprising a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing at least one inner pocketed spring and at least one cushion pad, the piece of 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 first and second plies being joined by transverse seams between adjacent inner pocketed springs.

13. The pocketed spring assembly of claim 8 , wherein each of said cushion pads is made at least partially of foam.

14. The pocketed spring assembly of claim 8 , wherein each of the cushion pads is individually pocketed.

15. A bedding or seating product comprising:
a pocketed spring assembly;
an edge support extending around the perimeter of the pocketed spring assembly, the edge support comprising at least one perimeter string of springs, each of the at least one perimeter string comprising a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing one inner pocketed spring and at least one cushion pad, the piece of fabric being joined to itself along a longitudinal seam and having first and second opposed plies of fabric on opposite sides of the inner pocketed springs, the fabric of said first and second plies being joined by transverse seams.

16. The product of claim 15 , wherein the pocketed spring assembly comprises multiple interior strings of springs.

17. The product of claim 16 , wherein said interior strings of springs extend longitudinally.

18. The product of claim 16 , wherein said interior strings of springs extend transversely.

19. The product of claim 15 , wherein each of the interior strings comprises a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing at least one inner pocketed spring and at least one cushion pad, the piece of 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 first and second plies being joined by transverse seams between adjacent inner pocketed springs.

20. The product of claim 19 , wherein each of the inner pocketed springs within the at least one perimeter string has a smaller diameter than the inner pocketed springs of the pocketed spring assembly.
