Stackable bedding foundation having pocketed topper

Abstract

A nestably stackable spring assembly is incorporated into a bedding foundation. The foundation includes a pocketed spring assembly which functions as a cushioning layer, thereby providing additional comfort. The spring assembly includes a number of corrugated support wires having alternating flattened peaks and valleys. The pocketed spring assembly fits inside a border which provides edge firmness to the foundation.

1 . A bedding foundation comprising:
 a rectangular base;   a spring assembly fixedly attached atop the base;   a cushioning pad overlying the spring assembly;   the spring assembly comprising;   a generally rectangular border wire having two parallel sides and two parallel ends;   a plurality of spaced and longitudinally-extending support wires extending between the border wire ends, each support wire having a plurality of peaks and a plurality of valleys, flattened distal portions of the peaks being generally coplanar with the border wire and flattened distal valley portions being vertically displaced beneath and intermediate of the distal peak portions;   a pocketed spring assembly on top of said cushioning pad; and   a fabric covering surrounding the spring assembly, the base, the pocketed spring assembly and the cushioning pad.   
     
     
         2 . The bedding foundation of  claim 1  further comprising:
 a plurality of longitudinally-spaced, parallel, and transversely-extending upper connector wires parallel to the border wire ends and having ends connected to the border wire sides, the upper connector wires being connected intermediate of their ends along their lengths thereof to the distal peak portions of the support wires.   
     
     
         3 . The bedding foundation of  claim 1  wherein longitudinal voids between the distal peak portions are of a dimension greater than the distal valley portions. 
     
     
         4 . The bedding foundation of  claim 1  wherein the rectangular base comprises a rectangular base frame and a plurality of intermediate transverse slats. 
     
     
         5 . The bedding foundation of  claim 1  further comprising a border around the pocketed spring assembly. 
     
     
         6 . The bedding foundation of  claim 1  wherein the pocketed spring assembly comprises strings of springs joined together. 
     
     
         7 . The bedding foundation of  claim 6  wherein the strings of spring extend longitudinally. 
     
     
         8 . The bedding foundation of  claim 6  wherein the strings of springs extend transversely. 
     
     
         9 . The bedding foundation of  claim 1  wherein border wire sides are longer than the border wire ends. 
     
     
         10 . The bedding foundation of  claim 1  wherein each of the support wires is a continuous length of wire. 
     
     
         11 . The bedding foundation of  claim 5  wherein the border is made of foam. 
     
     
         12 . The bedding foundation of  claim 5  wherein the border is adhesively secured to the cushioning pad. 
     
     
         13 . A bedding foundation comprising:
 a rectangular base comprising a rectangular base frame and a plurality of intermediate transverse slats;   a spring assembly fixedly attached atop the base, the spring assembly comprising;   a generally rectangular border wire having two parallel sides and two parallel ends;   a plurality of spaced and longitudinally-extending support wires extending between the border wire ends, each support wire having a plurality of peaks and a plurality of valleys, flattened distal portions of the peaks being generally coplanar with the border wire and flattened distal valley portions being vertically displaced beneath and intermediate of the distal peak portions;   a cushioning pad overlying the spring assembly and secured to the border wire;   a generally rectangular border secured to the cushioning pad;   a pocketed spring assembly inside said generally rectangular border; and   a fabric covering surrounding the base, the spring assembly, the cushioning pad, the border and the pocketed spring assembly.   
     
     
         14 . The bedding foundation of  claim 13  wherein the support wires are generally parallel with each other. 
     
     
         15 . The bedding foundation of  claim 13  wherein the pocketed spring assembly comprises strings of springs joined together. 
     
     
         16 . The bedding foundation of  claim 15  wherein the strings of spring extend longitudinally. 
     
     
         17 . The bedding foundation of  claim 15  wherein the strings of springs extend transversely. 
     
     
         18 . The bedding foundation of  claim 13  wherein the border is made of foam. 
     
     
         19 . The bedding foundation of  claim 13  wherein the border is adhesively secured to the cushioning pad. 
     
     
         20 . A bedding foundation comprising:
 a rectangular base comprising a rectangular base frame and a plurality of intermediate transverse slats;   a spring assembly fixedly attached atop the base, the spring assembly comprising;   a generally rectangular border wire having two parallel sides and two parallel ends;   a plurality of spaced and longitudinally-extending support wires extending between the border wire ends, each support wire having a plurality of peaks and a plurality of valleys, flattened distal portions of the peaks being generally coplanar with the border wire and flattened distal valley portions being vertically displaced beneath and intermediate of the distal peak portions;   a cushioning pad overlying the spring assembly and secured to the border wire;   a generally rectangular border secured to the cushioning pad;   a pocketed spring assembly inside said generally rectangular border.
