         7 . The adjustable shelf system as defined in  claim 6 , wherein the at least two wood vertical columns are located proximate to the corners of the at least one shelf.  
     
     
         8 . The adjustable shelf system as defined in  claim 6 , further comprising a drawer slide assembly attached to the at least one support member and the at least one shelf.  
     
     
         9 . The adjustable shelf system as defined in  claim 6 , wherein the at least one support member is made of a wood material.  
     
     
         10 . The adjustable shelf system as defined in  claim 6 , wherein each of the at least two wood vertical columns includes a back wall configured to prevent the protrusion from moving through the at least one column-notch.  
     
     
         11 . A furniture cabinet with adjustable shelf system comprising: 
 a furniture cabinet;    at least four wood vertical columns secured to the inside of the furniture cabinet, each column defining at least two column-notches;    at least two support members, each support member having a protrusion configured to removably engage, by horizontal movement, at least one of the two column-notches;    at least two slider assemblies, each drawer slide assembly attached to one of the at least two support members; and    a shelf attached to the at least two slider assemblies and configured to horizontally slide using the at least two slider assemblies, into and out of the furniture cabinet.    
     
     
         12 . The furniture cabinet with adjustable shelf system as defined in  claim 11 , wherein the at least four wood vertical columns located proximate to the corners of the furniture cabinet.  
     
     
         13 . The furniture cabinet with adjustable shelf system as defined in  claim 11 , wherein the at least two support members are made of a wood material.  
     
     
         14 . The furniture cabinet with adjustable shelf system as defined in  claim 11 , wherein the at least two support members are made of a non-metallic material.  
     
     
         15 . The furniture cabinet with adjustable shelf system as defined in  claim 11 , wherein each of the at least four wood vertical columns includes a back wall configured to prevent the protrusion from moving through the at least one of the two column-notches.  
     
     
         16 . An adjustable shelf system comprising: 
 four wood vertical columns, each column defining a plurality of column-notches along the length of columns, each column mounted proximate to the interior corners of a furniture cabinet;    two wood support members, each support member having two ends, each end being configured with a protrusion to removably engage, by horizontal movement, at least one of the plurality of column-notches, each support member supported in a horizontal position by at least two vertical columns, wherein the protrusion at each end of the support member is removably engaged with one of the plurality of column-notches;    two drawer slides, each drawer slide attached to one of the two wood support members; and    a wood shelf having two sides, each side configured to attach to one of the two drawer slides.    
     
     
         17 . The adjustable shelf system as defined in  claim 16 , wherein each of the four wood vertical columns includes a back wall configured to prevent the protrusion from moving through at least one of the plurality of column-notches.  
     
     
         18 . A method for vertically adjusting a shelf, the method comprising: 
 dismounting the shelf from a first and second support member;    moving the first support member in only a horizontal direction to disengage a protrusion on the first support member from a corresponding column-notch defined by a first vertical column;    relocating the first support member to a desired different level along the first vertical column by engaging the protrusion on the first support member with the corresponding column-notch, at the desired level, of the first vertical column;    moving the second support member in only a horizontal direction to disengage a protrusion on the second support member from a corresponding column-notch defined by a second vertical column;    relocating the second support member to a desired different level along the second vertical column by engaging the protrusion on the second support member with the corresponding column-notch, at the desired level, of the second vertical column; and    mounting the shelf on the first and second support members.
