1 . An appendage that is retrofittable to an office chair for converting said office chair into a computer workplace; 
 said office chair being characterized by comprising a seat supported by a central column, having a feet assembly attached thereto,    wherein said appendage comprises a chassis coupled to a seat connector and a monitor supporting structure;    said seat connector adapted to facilitating connection of said chassis to said central column of said office chair and said monitor support structure for supporting a computer monitor thereon.    
     
     
         2 . The appendage of  claim 1  wherein said monitor support structure comprises a monitor support tray.  
     
     
         3 . The appendage of  claim 1  wherein said chassis includes at least one elongated supporting rail having an arcuate form.  
     
     
         4 . The appendage of  claim 1  further comprising a means for varying the position and angle of said monitor support structure with respect to said chair.  
     
     
         5 . The appendage of  claim 1  wherein said chassis comprises a pair of tubular guide rails separated from each other by a fixed distance along their length.  
     
     
         6 . The appendage of  claim 4  wherein said means comprises an attachment for attaching said monitor support structure to said chassis, said attachment being attachable to said chassis in a range of positions along the length of said chassis, allowing variation in position of a computer monitor on said monitor support structure with respect to the eyes of a user seated on said chair.  
     
     
         7 . The appendage of  claim 4  wherein said means comprises a compression drive for supporting and holding said monitor support structure.  
     
     
         8 . The appendage of  claim 7  wherein said drive is situated between a bracket affixed to said chassis below said monitor support structure and the bottom surface of said monitor support structure.  
     
     
         9 . The appendage of  claim 4  wherein said means comprises two pairs of auxiliary rollers affixed to said monitor support structure, enabling said monitor support structure to slide freely with respect to said chassis.  
     
     
         10 . The appendage of  claim 4  wherein said means comprises said seat connector, being attachable to said chassis in a range of positions along length thereof.  
     
     
         11 . The appendage of  claim 10  wherein said seat connector is adapted to allow variation in viewing of angle and distance of monitor on monitor support structure from the eyes of a user seated on said office chair.  
     
     
         12 . The appendage of  claim 4  wherein attached to said chassis there is provided at least one foot pedal for application of a force on said chassis for moving it from a first position to a second position with respect to said office chair.  
     
     
         13 . The appendage of  claim 12  further comprising a helical spring configured as a contra to said force, for returning said chassis from said second position to said first position when said force is no longer applied to said at least one foot pedal.  
     
     
         14 . The appendage of  claim 4 , further comprising a first lock for locking position of said chassis with respect to said office chair.  
     
     
         15 . The appendage of  claim 4 , further comprising a second lock for locking position of said monitor support structure with respect to said chassis.
