A chair is provided comprising a seat assembly including a seat back and a seat bottom and a support frame including a left leg assembly and right leg assembly connected by a transverse support member. The seat back is pivotably connected to each of the leg assemblies such that an upper portion of the seat back pivots in relation to the leg assemblies between a first seat back position and a second seat back position. The seat bottom is rotatable in relation to the seat back between an upright position and a horizontal position. The seat bottom is slidingly engaged with the leg assemblies such that pivoting of the seat backward from the first seat back position to the second seat back position causes the seat bottom to slide forward from a first seat bottom position to a second seat bottom position.

A stackable chair that is capable of being ganged with a further like chair in side-by-side relationship, including an upper frame adapted to receive and support a seating platform, and a backrest platform for supporting a user seated on the chair. The upper frame is attached to a lower frame having a left and right sides, each said having a pair of leg members connected underneath the lower frame, each of the leg members having a lower end to engage the supporting surface for the chair, and having an upper end. The right legs connect to a right frame member attached to the lower frame right side. The left legs connect to a left frame member attached to the lower frame left side. A left side and a right side coupling support extend respectively on top of left and right frame members. The left side coupling support includes a left extension having a coupling hook extending outward. The right side coupling support includes a right extension having a lower surface enclosing a downward opening slot aligned parallel with the right side frame member. In a ganged setup, the left coupling hook of one chair is insertable into the right slot of the second chair of a like chair. The ganged chairs, when disassembled, can be stacked vertically for ease of transfer. The chairs provide rigid connections and compact configurations when ganged or stacked.

A vertical stacking leg-over-leg ganged chair is attachable side-by-side and includes an upper frame adapted to receive and support a seating platform, and a lower frame supporting the upper frame, and a backrest for supporting a user seated in the chair. The ganged chair includes a front pair of legs angled frontward, and a rear pair of legs angled rearward, each pair connected underneath the lower frame. The right legs are connected to a right frame member, and the left legs to a left frame member, with the left frame member being of a lesser length than the right frame member. In a side-by-side ganged setup, the wider spaced apart right legs of one ganged chair fit over the left legs of a second like chair, forming a single width leg unit on either side of the ganged chairs. Each upper portion of the left legs includes an elongated slot that accepts an elongated lug on the upper portion of each right leg, for connective support when chairs are attached horizontally. The configuration of legs, the angles of the legs, and the rearward angle of the backrest, allow the ganged chair to be stacked vertically for ease of transfer. The leg-over-leg structure allows connection side-to-side, providing a lesser overall width of chairs when in the ganged configuration.

A stackable chair has supporting side members that comprise two bars that cross one another in non-contacting relation to form a substantially X-shaped configuration, the two bars capable of flexing movement relative to one another, so that the chair can flex in response to the weight and movement of the user.
