ABSTRACT:
A new and improved selectable height chair apparatus includes a chair assembly which includes a plurality of first leg assemblies. A plurality of second leg assemblies are provided, and a plurality of hinge assemblies connect the second leg assemblies to the first leg assemblies. The second leg assemblies are capable of being selectively rotated around the hinge assemblies such that the second leg assemblies can be positioned in a short-legged position wherein the second leg assemblies are oriented at a non-straight angle with respect to the first leg assemblies and such that the second leg assemblies can be positioned in a long-legged position wherein the second leg assemblies are oriented at a straight angle with respect to the first leg assemblies. A plurality of lock assemblies are provided for selectively locking the second leg assemblies in a long-legged position with respect to the first leg assemblies. The first leg assemblies diverge from their respective connections with the seat assembly. A first foot print of the second feet assemblies, when the second leg assemblies are in a long-legged position, is of a first foot print length. A second foot print of the second feet assemblies, when the second leg assemblies are in a short-legged position, is of a second foot print length. The second foot print length is greater than the first foot print length.
