       5 . The chair of  claim 1  further comprising a modular support member coupled to said mount.  
   
   
       6 . The chair of  claim 5  wherein the coupling between said modular support member and said mount is non-permanent and can be made at variable positions on said support member.  
   
   
       7 . The chair of  claim 6  wherein said coupling between said modular support member and said mount position is made using a locking pin mechanism.  
   
   
       8 . The chair of  claim 5  wherein said knee support pivot is coupled to said modular support member.  
   
   
       9 . The chair of  claim 8  wherein the coupling between said modular support member and said knee support pivot is non-permanent and may be made at variable positions on said support member.  
   
   
       10 . The chair of  claim 9  wherein said coupling between said modular support member and said knee support pivot is made using a locking pin mechanism.  
   
   
       11 . The chair of  claim 5  further comprising a thoracic support pad coupled to said modular support member.  
   
   
       12 . The chair of  claim 13  wherein the coupling between said modular support member and said thoracic support pad is non-permanent and be made at variable positions on said modular support member.  
   
   
       13 . The chair of  claim 12  wherein said coupling between said modular support member and said thoracic support pad is made using a locking pin mechanism.  
   
   
       14 . The chair of  claim 11  wherein said thoracic support pad is a chest support pad.  
   
   
       15 . The chair of  claim 1  wherein said seat may pivot on said seat base pivot so as to present an inclined, a declined, or a substantially horizontal position.  
   
   
       16 . The chair of  claim 5  further comprising an armrest coupled to said modular support member.  
   
   
       17 . The chair of  claim 16  further comprising a tray coupled to said armrest.  
   
   
       18 . The chair of  claim 5  further comprising a head support coupled to said modular support member.  
   
   
       19 . The chair of  claim 5  further comprising a work surface coupled to said modular support member.  
   
   
       20 . The chair of  claim 1  wherein said chair base comprises a plurality of articulating support legs.  
   
   
       21 . The chair of  claim 1  wherein said chair base is adapted for permanent or semi-permanent attachment to the floor.  
   
   
       22 . A chair comprising an improvement wherein the improvement comprises:
