to one another and in which the pockets 42 are closed by a longitudinal seam 44 of a
similar thermal weld.
After the rows or strips of pocketed coil springs 22 are secured together by
securement of side surfaces 54, 56 to side surfaces of adjacent strips and a sufficient
number of those strips have been adhered together to extend for the full width of a
mattress, the spring interior 21 is completed by securement of the border wires 25 on
the top and bottom edges of the spring interior 21. Thereafter, the mattress 20 is
completed by placement of the pads 19 over the top and bottom surfaces of the spring
interior 21, and the complete spring interior, including the pads, are encased within
conventional ticking or upholstered covering material.
Figures 3 and 4 illustrate a second embodiment of Long's invention. This
embodiment is identical to the embodiment of Figures 1 and 2, except that it includes,
as a part of the spring interior 21', foam pads or foam plies 60 positioned between each
of the strips 22 of pocketed springs and adhered or otherwise secured to the sidewalls
54, 56 of the strips. In this embodiment, each ply of foam material extends for the full
length of the strip and is of the approximately the same height as the transverse
dimension of the strip. In one preferred embodiment, the strip is approximately three
centimeters in thickness, but this dimension may be varied depending upon the desired
