Abstract

A coil spring assembly is provided that includes rows of pocketed coil springs, a top securing sheet and a bottom securing sheet. The assembly may be partitioned into sections of varying firmness. The rows of coil springs are positioned between the top and bottom securing sheets. Coil spring assemblies are provided that further include top and bottom securing members that further stabilize the pocketed coil springs.

Claims

1. A coil spring assembly, comprising:

rows of coil springs, each of said coil springs having a top surface, a bottom surface and a longitudinal axis, each of said coil springs having a uniform wire diameter and being heat-tempered prior to being individually encased in a pocket, said pocket including a top surface, a bottom surface and a side wall connecting said top surface and said bottom surface, a plurality of said coil springs being perimetrical coil springs, said pocketed coil springs forming a coil spring assembly partitioned into at least two sections, one of said sections being firmer than the other section, said firmer section formed from coil springs having a height in their relaxed state greater than the height of coil springs in said other section in their relaxed state;

a top securing sheet, said top securing sheet having an inner face and an outer face; and

a bottom securing sheet, said bottom securing sheet having an inner face and an outer face, said rows of coil springs being positioned between said top securing sheet and said bottom securing sheet.

2. The coil spring assembly of claim 1, said assembly further comprising a top border member, said top border member connected to said top surface of said perimetrical coil springs.

3. The coil spring assembly of claim 2, wherein said top border member is connected to said perimetrical coil springs by securing wire.

4. The coil spring assembly of claim 1, said assembly further comprising a bottom border member, said bottom border member connected to said bottom surface of said perimetrical coil springs.

5. The coil spring assembly of claim 4, wherein said bottom border member is connected to said perimetrical coil springs by securing wire.

6. The coil spring assembly of claim 1, wherein said inner face of said top securing sheet is connected to said top surface of a plurality of said pockets.

7. The coil spring assembly of claim 6, wherein said inner face of said top securing sheet is connected to said top surface of said plurality of said pockets by an adhesive.

8. The coil spring assembly of claim 1, wherein said inner face of said bottom securing sheet is connected to said bottom surface of a plurality of said pockets.

9. The coil spring assembly of claim 8, wherein said inner face of said bottom securing sheet is connected to said bottom surface of a plurality of said pockets by an adhesive.

10. The coil spring assembly of claim 1, wherein each of said coil springs has a uniform coil diameter.
