Wobble stool and base

Abstract

A wobble base provides a curved floor-contacting surface with one or more attachment points that removably couple the wobble base to a lower portion of a seating platform, such as a stool, thereby providing a wobble stool. The wobble base can be configured to convert an existing stool into a wobble stool by replacing one or more floor-contacting members with the wobble base. In a second embodiment, a seating platform, such as a stool, is provided with both traditional floor-contacting members, such as feet or casters, and with a wobble base that allows the traditional floor-contacting members to be removed and replaced with the wobble base, and allows the wobble base to be removed and replaced with the traditional floor-contacting members. This allows the seating platform to be dynamically reconfigured as needed.

1 . A wobble base for a seating platform comprising:
 a curved floor-contacting surface; and   at least one attachment point that allows the wobble based to be removably coupled to a lower portion of the seating platform.   
     
     
         2 . The wobble base of  claim 1  wherein the curved floor-contacting surface comprises a substantially flat portion coupled to at least one curved portion. 
     
     
         3 . The wobble base of  claim 1  wherein the curved floor-contacting surface comprises a substantially dome-shaped portion. 
     
     
         4 . The wobble base of  claim 1  wherein each attachment point comprises a post pointing substantially up that is pushed into a corresponding receptacle pointing substantially down on a lower portion of the seating platform. 
     
     
         5 . The wobble base of  claim 4  wherein each receptacle pointing down on the lower portion of the seating platform is configured to receive a corresponding floor-contacting member such that the wobble base may be replaced by at least one floor-contacting member. 
     
     
         6 . A wobble base comprising:
 a curved floor-contacting surface; and   four posts pointing substantially up that are pushed into four corresponding receptacles pointing substantially down on a lower portion of a seating platform to attach the wobble base to the seating platform.   
     
     
         7 . The wobble base of  claim 6  wherein the curved floor-contacting surface comprises a substantially flat portion coupled to at least one curved portion. 
     
     
         8 . The wobble base of  claim 6  wherein the curved floor-contacting surface comprises a substantially dome-shaped portion. 
     
     
         9 . The wobble base of  claim 6  wherein each of the four corresponding receptacles pointing substantially down on the lower portion of the seating platform is configured to receive a corresponding floor-contacting member such that the wobble base may be replaced by four floor-contacting members. 
     
     
         10 . A seating apparatus comprising:
 a seating platform having a lower portion that comprises at least one receptacle; and   a wobble base comprising:
 a curved floor-contacting surface; and 
 at least one attachment point that allows the wobble based to be removably coupled to the at least one receptacle on the seating platform. 
   
     
     
         11 . The seating apparatus of  claim 10  wherein the curved floor-contacting surface comprises a substantially flat portion coupled to at least one curved portion. 
     
     
         12 . The seating apparatus of  claim 10  wherein the curved floor-contacting surface comprises a substantially dome-shaped portion. 
     
     
         13 . The seating apparatus of  claim 10  wherein the lower portion of the seating platform comprises four receptacles and the at least one attachment point comprises four attachment points corresponding to the four receptacles. 
     
     
         14 . The seating apparatus of  claim 10  wherein each attachment point comprises a post pointing substantially up that engages a corresponding receptacle pointing substantially down on the lower portion of the seating platform. 
     
     
         15 . The seating apparatus of  claim 14  wherein each receptacle pointing substantially down on the lower portion of the seating platform is configured to receive a corresponding floor-contacting member such that the wobble base may be replaced by a plurality of the floor-contacting members. 
     
     
         16 . A method for providing a seating apparatus with a removable wobble base comprising:
 providing a seating platform having a lower portion that comprises at least one receptacle;   providing a wobble base comprising:
 a curved floor-contacting surface; and 
 at least one attachment point that allows the wobble based to be removably coupled to the at least one receptacle on the seating platform; 
   pushing the at least one attachment point on the wobble base into the at least one receptacle on the seating platform.   
     
     
         17 . The method of  claim 16  wherein the curved floor-contacting surface comprises a substantially flat portion coupled to at least one curved portion. 
     
     
         18 . The method of  claim 16  wherein the curved floor-contacting surface comprises a substantially dome-shaped portion. 
     
     
         19 . The method of  claim 16  wherein the lower portion of the seating platform comprises four receptacles and the at least one attachment point on the wobble base comprises four attachment points corresponding to the four receptacles. 
     
     
         20 . The method of  claim 16  wherein each attachment point on the wobble base comprises a post pointing substantially up that engages a corresponding receptacle pointing substantially down on the lower portion of the seating platform. 
     
     
         21 . The method of  claim 20  wherein each receptacle pointing down on the lower portion of the seating platform is configured to receive a corresponding floor-contacting member such that the wobble base may be replaced by a plurality of the floor-contacting members.
