A combination step stool and mechanic's seat in the form of a molded plastic, generally parallelepiped configuration includes a seat on one side supported on casters on the opposite side with a step stool surface adjacent the backside of the seat and spaced from a front side surface of the seat which includes a recess tray for tools and other items.

1 . A combination step stool and seat comprising, in combination: 
 a six sided, unitary, hollow, single molded plastic, generally rectangular parallelepiped assembly of walls including a first side wall, an opposed second side wall with a molded seat, said seat including a back support section with a hand grip passage, a transverse third side wall between the first side wall and second side walls, said third side wall comprising a generally flat, planar step surface and said back support section along one side thereof, a transverse fourth side wall spaced from and generally parallel to the third wall for support of said combination assembly as a step stool, said first wall being positionable at the floor to define a creeper with a molded seat supported on the molded third side wall, said fourth wall being positionable at the floor in an alternative orientation of said assembly to define said step stool, said fourth wall comprising an upper wall section, a spaced lower wall section with an opening cut through the fourth wall to the interior of the assembly;    a separate molded recess shelf section in the form of a give sided bucket, said recess shelf wall section mounted to the fourth wall and comprising a bucket shaped insert with an open side open outwardly from the fourth wall, the open side including a rim fitted into the cut in the fourth wall and generally aligned with the wall sections of the fourth wall; and    casters mounted to the first wall.    
     
     
         2 . The combination of  claim 1  wherein the second wall includes arm support sections on each side of the molded seat extending from the back support section along the edge of the seat.  
     
     
         3 . The combination of  claim 1  wherein the first wall includes a molded step.  
     
     
         4 . The combination of  claim 1  molded recess comprising a bushing counterbore in a molded plastic wall with an internal counterbore top wall, said counterbore top wall fused to a molded plastic counterbore wall of an adjacent counterbore molded in a wall adjacent the first wall to thereby reinforce the bushing counterbore, said bushing positioned to receive a stem of a wheel housing.  
     
     
         5 . The combination of  claim 4  including a plurality of bushings each retained in a said bushing counterbore molded in a wall reinforced by an adjacent counterbore molded in a wall.  
     
     
         6 . A molded plastic stool having a base support wall with an outside face and a recessed first bushing counterbore in said base support wall, said first counterbore including a top wall, said first bushing counterbore further including a bushing of a caster assembly, said stool further including a secondary, integrally molded wall extending upwardly from the base support wall separate from said counterbore base wall, said secondary molded wall including an second molded counterbore with a counterbore lateral wall fused to said top wall of the first bushing counterbore to reinforce said first bushing counterbore, said bushing positioned in said first bushing counterbore to received a stem of a wheel housing, said first counterbore including a bushing therein with an integral peripheral flange attached to the outside of the base support wall.
