         9 . The seating system of  claim 8 , wherein the first engagement member has a pin and each second engagement member in the plurality of second engagement members is a notch in the outer race shaped to receive the pin of the first engagement member. 
     
     
         10 . The seating system of  claim 1 , wherein the mount comprises a mount sleeve moveably coupled to the mount, the mount sleeve being movable along a longitudinal axis of the mount,
 wherein the upper body support is mounted to the mount sleeve such that the upper body support is movable with the mount sleeve.   
     
     
         11 . A seating system, the seating system comprising:
 a base extending from a lower end to an upper end;   a lower body support coupled to the base proximate the upper end of the base, the lower body support for supporting a lower body of a user;   a mount extending from a lower end to an upper end, the lower end being coupled to the base proximate the upper end of the base, the mount having a plurality of first mounting members; and   an upper body support having a user side being shaped to receive an upper body of the user and a mounting side, the mounting side of the upper body support being removably coupled to the mount proximate the upper end of the mount,   wherein the mount has a plurality of first mounting members, the mounting side of the upper body support has a plurality of second mounting members, and the upper body support is removably couplable to the mount by coupling the first mounting members and the second mounting members.   
     
     
         12 . The seating system of  claim 11 , wherein one of the plurality of first mounting members and the plurality of second mounting members comprises locating pins and the other of the plurality of first mounting members and the plurality of second mounting members comprises bores correspondingly shaped to receive the plurality of locating pins. 
     
     
         13 . The seating system of  claim 11 , wherein the plurality of first mounting members and the plurality of second mounting members are magnetically couplable. 
     
     
         14 . The seating system of  claim 11 , wherein the upper body support is a first upper body support and the seating system further comprises a second upper body support, the first upper body support being replaceable with the second upper body support.
