Abstract:
1. A chair apparatus with multiple pivot axes, said chair apparatus comprising: (a) a seat portion comprising an inflatable balloon capable of pivotal movement about said multiple pivot axes and along a surface, said inflatable balloon defining an upper tangential plane including an upper tangent point on said balloon, and a lower tangential plane including a lower tangent point on said balloon, said lower tangential plane being substantially parallel to said upper tangential plane, said balloon further defining a midplane extending substantially perpendicularly between said upper and lower tangential planes to substantially bisect said balloon into a front portion on a first side of said mid-plane and a rear portion on a second side of said mid lane; (b) a frame limiting such pivotal movement only when said chair apparatus is placed in a supported orientation with a pivot stabilizer portion of said frame in contact with said surface; and (c) a retention mechanism adapted to removably secure said seat portion to said frame, wherein said frame includes said pivot stabilizer portion only on said second side of said midplane.
