1. An article of furniture comprising:
- a substantially rigid base frame having four feet regularly arranged in longitudinally aligned front and rear pairs which pairs are spaced transversely from each other to provide a stable support for said article upon a horizontal surface, said front pair of feet being wheels;
said frame including longitudinally spaced sub-frames extending transversely and from top-to-bottom of said frame, said sub-frames being rigidly interconnected by vertically and transversely spaced horizontally extending frame elements and by brace means;
two of said frame elements comprising a pair of longitudinally spaced horizontal supports each rigidly attached at transversely spaced locations on said frame and having end portions projecting transversely beyond a rear side of said frame;
a horizontal seat carried on and extending between said end portions;
said article further including a table top having a length and a width, said table top being selectively movable between a horizontal position wherein said table top is supported on a top section of said frame, and a lower position wherein said table top is supported on said frame in a position extending upwardly from one longitudinal edge of said seat so as to provide a backrest, guide means interacting between said table top and said frame to accommodate such movement of the table top;
retainer means selectively operable to secure said table top in said horizontal position wherein said table top is transversely offset relative to said seat;
wherein said frame carries support means that extend over a distance in the front-to-rear direction that corresponds to a major portion of the width of the table top such that in the horizontal position the table top is stably supported on said support means over a major part of the width of said table top;
said article of furniture having a center of gravity and having a weight distribution such that when said article of furniture is supported on a horizontal surface and the weight of a user is concentrated on the front of said table top, the article of furniture remains stable.

18. An article of furniture comprising:
-
a substantially rigid base frame having four feet regularly arranged in longitudinally aligned front and rear pairs which pairs are spaced transversely from each other to provide a stable support for said article upon a horizontal surface; said frame including longitudinally spaced sub-frames extending transversely and from top-to-bottom of said frame, said sub-frames being rigidly interconnected by vertically and transversely spaced horizontally extending frame elements and by brace means; two of said frame elements comprising a pair of longitudinally spaced horizontal supports each rigidly attached at transversely spaced locations on said frame and having end portions projecting transversely beyond a rear side of said frame; a horizontal seat carried on and extending between said end portions; a table top having a length and a width, said table top being selectively movable between a horizontal position wherein said table top is supported on a top section of said frame, and a lower position wherein said table top is supported on said frame in a position extending upwardly from one longitudinal edge of said seat so as to provide a backrest; guide means interacting between said table top and said frame to accommodate such movement of the table top said guide means comprising at each end of said frame a longitudinally extending pivot pin received within a corresponding transversely extending slot on the underside of said table top, said pivot pins being substantially coaxial, and said table top being movable transversely relative to and pivotable about the axis of said pivot pins; retainer means selectively operable to secure said table top in said horizontal position wherein said table top is transversely offset relative to said seat, said retainer means comprising retaining pins that are insertable through said slots when the table top is in its horizontal position, each said retaining pin being received within a socket in said frame to inhibit horizontal or pivotal movement of the table top relative to said frame; wherein said frame carries support means that extend over a distance in the front-to-rear direction that corresponds to a major portion of the width of the table top such that in the horizontal position the table top is stably supported on said support means over a major part of the width of said table top; said article of furniture having a center of gravity and having a weight distribution such that when said article of furniture is supported on a horizontal surface and the weight of a user is concentrated on the front of said table top, the article of furniture remains stable. - View Dependent Claims (19, 20, 21, 22, 23, 24)
