     Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims. 
     SUMMARY OF THE INVENTION 
     The present invention features a mobile seat system ( 100 ) for positioning a user low to a ground surface. In some embodiments, the system ( 100 ) comprises (a) a base ( 110 ), a plurality of caster wheels ( 120 ) are disposed on a bottom surface ( 116 ) of the base ( 110 ), a threaded protrusion ( 130 ) extends upwardly from a top surface ( 115 ) of the base ( 110 ); (b) a base cushion ( 210 ), wherein a threaded indentation ( 230 ) is disposed in the bottom surface ( 216 ) of the base cushion ( 210 ), the threaded indentation ( 230 ) is adapted to accept the threaded protrusion ( 130 ) of the base ( 110 ) to temporarily attach the base cushion ( 210 ) to the base ( 110 ); and (c) a support cushion ( 310 ), a back support component ( 320 ) extends upwardly from the support cushion ( 310 ) to support a user&#39;s back, wherein a threaded indentation ( 330 ) is disposed in a bottom surface of the support cushion ( 310 ), the threaded indentation ( 330 ) is adapted to accept the threaded protrusion ( 130 ) of the base ( 110 ) to temporarily attach the support cushion ( 310 ) to the base ( 110 ). In some embodiments, the base cushion ( 210 ) and support cushion ( 310 ) are interchangeable on the base ( 110 ). In some embodiments, the system ( 100 ) positions the user close to the ground surface. In some embodiments, the wheels ( 120 ) are arranged around the outer edge of the bottom surface ( 116 ) of the base ( 110 ). In some embodiments, the base cushion ( 210 ) covers the entire top surface ( 116 ) of the base ( 110 ).

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Following is a list of elements corresponding to a particular element referred to herein:
           100  mobile seat system     110  base     115  top surface     116  bottom surface of base     120  wheels     130  threaded protrusion     210  base cushion     216  bottom surface of base cushion     230  threaded indentation     310  support cushion     320  back support component     330  threaded indentation       

     Referring now to  FIG. 1-6 , the present invention features a mobile seat system ( 100 ). The system ( 100 ) of the present invention helps position the user near the ground surface. As shown in  FIG. 1 , the system ( 100 ) comprises a base ( 110 ). Disposed on the bottom surface ( 116 ) of the base ( 110 ) is a plurality of wheels ( 120 ). The wheels ( 120 ) may be arranged in any particular fashion on the bottom surface ( 116 ). In some embodiments, the wheels ( 120 ) are arranged along the outer edge of the bottom surface ( 116 ) of the base ( 110 ). In some embodiments, the wheels ( 120 ) are caster wheels. 
     The system ( 100 ) comprises a base cushion ( 210 ). The base cushion ( 210 ) is removably attached to the top surface ( 115 ) of the base ( 110 ). The base cushion ( 210 ) covers the entire top surface ( 115 ) of the base ( 110 ). 
     The base cushion ( 210 ) can be attached to and removed from the base ( 110 ) via a screw-like mechanism. As shown in  FIG. 4 , a threaded protrusion ( 130 ) is disposed on and extends upwardly from the top surface ( 115 ) of the base ( 110 ). A threaded indentation ( 230 ) is disposed in the bottom surface ( 216 ) of the base cushion ( 210 ). The threaded indentation ( 230 ) is adapted to accept the threaded protrusion ( 130 ) to attach the base cushion ( 210 ) to the base ( 110 ) (see  FIG. 4 ). 
     The system ( 100 ) further comprises a support cushion ( 310 ) removably attached to the base ( 110 ) in the same manner as the base cushion ( 210 ). The support cushion ( 310 ), as shown in  FIG. 6 , comprises a back support component ( 320 ), which supports the users back when he/she is sitting atop the support cushion ( 310 ). 
     The support cushion ( 310 ) can be attached to and removed from the base ( 110 ) via a screw-like mechanism. As shown in  FIG. 6 , a threaded indentation ( 330 ) is disposed in the bottom surface of the support cushion ( 310 ). The threaded indentation ( 330 ) is adapted to accept the threaded protrusion ( 130 ) of the base ( 110 ) to attach the support cushion ( 310 ) to the base ( 110 ) (see  FIG. 6 ). 
     The base cushion and support cushion position the user close to the ground surface. This allows the user to work at a low level without bending over or having to kneel. 
     Without wishing to limit the present invention to any theory or mechanism, the present invention is advantageous because the system features a separate base with two attachable cushions. The base is generally round. Wheels, e.g., caster wheels, are attached to the bottom surface in a manner that helps prevent the tipping of the base.
