Mattress and Coil-in-Coil Assembly

Abstract

A mattress and coil-in-coil assembly. The mattress includes a cover, a frame, a plurality of spacing coils, and a plurality of coil-in-coil assemblies. The coil-in-coil assembly includes a first coil and a second coil positioned substantially within the first coil. The second coil is pocketed and projects out of a first end of the first coil.

1 . A mattress comprising: 
 a cover;    a frame;    a plurality of spacing coils;    a plurality of coil-in-coil assemblies comprising a first coil and a second coil, the second coil positioned substantially within the first coil; wherein a first end of the second coil projects out of a first end of the first coil.    
     
     
         2 . The mattress of  claim 1  wherein at least two of the plurality of spacing coils and the coil-in-coil assemblies are connected with a link.  
     
     
         3 . The mattress of  claim 2  wherein the link comprises a spring.  
     
     
         4 . The mattress of  claim 1  wherein the second coil includes a second end, wherein the second end of the second coil projects out of a second end of the first coil.  
     
     
         5 . The mattress of  claim 1  wherein a set of the plurality of spacing coils and coil-in-coil assemblies are arranged in a quincunx arrangement.  
     
     
         6 . The mattress of  claim 1  wherein the spacing coils comprise at least one of a simple coil and a coil-in-coil assembly.  
     
     
         7 . The mattress of  claim 1  wherein the first coil comprises a first spring rate and the second coil comprises a second spring rate  
     
     
         8 . The mattress of  claim 7  wherein the first spring rate is greater than the greater spring rate.  
     
     
         9 . The mattress of  claim 7  wherein the first spring rate and second spring rate are customized.  
     
     
         10 . The mattress of  claim 1  wherein the second coil comprises a pocketed coil.  
     
     
         11 . A coil-in-coil assembly comprising: 
 a first coil;    a second coil positioned substantially within the first coil; wherein the second coil includes a first end, the first end of the second coil projects out of a first end of the first coil.    
     
     
         12 . The assembly of  claim 11  wherein the second coil includes a second end, wherein the second end of the second coil projects out of a second end of the first coil.  
     
     
         13 . The assembly of  claim 11  wherein the first coil comprises a first spring rate and the second coil comprises a second spring rate.  
     
     
         14 . The assembly of  claim 13  wherein the first spring rate is greater than the second spring rate.  
     
     
         15 . The assembly of  claim 14  wherein the first spring rate and the second spring rate are customized.  
     
     
         16 . The assembly of  claim 11  further comprising four spacing coils positioned about the pocketed coil-in-coil assembly in a quincunx arrangement.  
     
     
         17 . The assembly of  claim 15  wherein the spacing coils comprise at least one of a simple coil and the coil-in-coil assembly.  
     
     
         18 . The assembly of  claim 15  wherein a set of the four spacing coils and the coil-in-coil assembly are connected with a link.  
     
     
         19 . The assembly of  claim 17  wherein the link comprises a spring.  
     
     
         20 . The assembly of  claim 11  wherein the second coil comprises a pocketed coil.
