Patent ID: 8083288

Claim:
A chair, comprising: a frame forming a chair portion, the frame having a lower portion and an upper portion, the lower portion including a first portion near the upper portion, a second portion spaced away from the first portion, a claw extending generally downward from the second portion, a latch extending generally downward from the first portion, and at least two frame legs extending generally downward, the latch being connected with the first portion and moving between closed and opened positions, the frame legs being adapted to support the frame upon a generally horizontal supporting surface; a base that releasably couples with the frame and that is adapted to support the frame above a generally horizontal supporting surface, the base having a saddle and extending generally upward from the supporting surface to the saddle, the saddle having opposite back and front edges, the front edge cooperating with the frame lower portion claw whereby the front edge is releasably captured in the claw, and the back edge cooperating with the frame lower portion latch whereby the back edge is releasably captured by the latch; the frame has opposite left and right sides and wherein the claw includes each of a claw notch, the first tooth extends toward the left side from the notch, and the second tooth extends toward the right side of the notch; the frame further comprises a receptacle defined between the claw and the latch; the saddle further includes a top surface that faces away from the supporting surface, and is sized and shaped with a rotationally asymmetric geometry; the receptacle and a perimeter edge of the saddle correspond with one another so that the base couples with the frame in a rotationally asymmetric configuration; the saddle front edge includes a pair of cooperating claw notches; and with the asymmetric configuration, the first tooth and second tooth can be engaged with the saddle only through the engagement of the first tooth with a first one of the cooperating claw notches and the second tooth with a second one of the cooperating claw notches.
