Body support system

Abstract

A body support includes a chassis defining a cavity. A spring pack is positioned in the cavity. The spring pack includes a plurality of strings. The strings each define a plurality of pockets. A spring is positioned in each of the pockets. The strings each have opposite top and bottom walls and a side wall extending from the top wall to the bottom wall. The side walls are air permeable. A comfort layer is positioned on top of the enclosure such that the comfort layer covers the spring pack.

What is claimed is: 
     
         1 . An assembly comprising:
 a fabric having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, the side wall being air permeable;   a spring encased by the fabric.   
     
     
         2 . The assembly recited in  claim 1 , wherein the top wall is non-air permeable. 
     
     
         3 . The assembly recited in  claim 1 , wherein the side wall includes a perforated material. 
     
     
         4 . The assembly recited in  claim 1 , wherein the side wall includes a perforated material, the perforated material configured to allow airflow therethrough at a rate of at least about 100 cubic feet per minute. 
     
     
         5 . The assembly recited in  claim 1 , wherein the top wall includes a non-perforated material and is non-air permeable. 
     
     
         6 . The assembly recited in  claim 1 , wherein the side wall and the top wall each include a perforated material, the perforated material of the top wall being coated such that the top wall is non-air permeable. 
     
     
         7 . A spring pack comprising:
 a plurality of strings, the strings each having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, inner surfaces of the walls defining a plurality of pockets, the side wall being air permeable; and   a spring positioned in each of the pockets.   
     
     
         8 . The spring pack recited in  claim 7 , wherein the side wall includes a perforated material. 
     
     
         9 . The spring pack recited in  claim 7 , wherein the side wall and the top wall each include a perforated material, the perforated material of the top wall being coated such that the top wall is non-air permeable. 
     
     
         10 . A body support comprising:
 a chassis defining a cavity;   a spring pack positioned in the cavity, the spring pack comprising a plurality of strings, the strings each defining a plurality of pockets, a spring being positioned in each of the pockets, the strings each having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, the side walls each being air permeable; and   a comfort layer positioned on top of the chassis such that the comfort layer covers the spring pack.   
     
     
         11 . The body support recited in  claim 10 , wherein the side walls each include a perforated material. 
     
     
         12 . The body support recited in  claim 10 , wherein the side walls and the top walls each include a perforated material and the perforated material of the top walls is coated such that the top walls are non-air permeable. 
     
     
         13 . The body support recited in  claim 10 , wherein the side walls and the top walls each include a perforated material such that the top walls are air permeable. 
     
     
         14 . The body support recited in  claim 10 , wherein the body support is configured such that ambient air moves through the comfort layer and then moves laterally between and through the spring pack after the ambient air moves through the comfort layer. 
     
     
         15 . The body support recited in  claim 10 , further comprising an enclosure, the spring pack being positioned in the enclosure, the enclosure being positioned in the cavity such that the comfort layer covers the enclosure. 
     
     
         16 . The body support recited in  claim 15 , wherein the enclosure comprises opposite top and bottom sides and a vertical side extending from the top side to the bottom side, the top side being air permeable. 
     
     
         17 . The body support recited in  claim 16 , wherein the body support is configured such that ambient air moves through the comfort layer and the top side, the ambient air being configured to move laterally within the enclosure after the ambient air moves through the top side. 
     
     
         18 . The body support recited in  claim 17 , wherein the ambient air moves through the spring pack as the ambient air moves laterally within the enclosure. 
     
     
         19 . The body support recited in  claim 17 , wherein the ambient air moves between the strings and through the side walls as the ambient air moves laterally within the enclosure. 
     
     
         20 . The body support recited in  claim 16 , wherein the body support is configured such that ambient air moves through the bottom side and into the enclosure, the ambient air being configured to move laterally within the enclosure after the ambient air moves through the bottom side, the ambient air moving through the top side and the comfort layer after moving laterally within the enclosure. 
     
     
         21 . The body support recited in  claim 20 , wherein the ambient air moves through the spring pack as the ambient air moves laterally within the enclosure. 
     
     
         22 . The body support recited in  claim 20 , wherein the ambient air moves between the strings and through the side walls as the ambient air moves laterally within the enclosure. 
     
     
         23 . The body support recited in  claim 10 , further comprising a base, the chassis being positioned on top of the base.
