A stackable chair includes a base with a pair of inverted U-shaped leg members. Each of the leg members includes a front leg portion, a rear leg portion, and a generally horizontal portion interconnecting the front and rear leg portions. The base also has a generally horizontal seat cushion frame extending between the U-shaped leg members with the transverse front spring reinforcement bar extending side-to-side. A back support frame has a generally vertical portion with an upper and lower end and a generally horizontal portion that extends from the lower end. The generally horizontal portion includes a transverse rear spring reinforcement bar. A spring member has one end interconnected with the front spring reinforcement bar and another end interconnected with the rear spring reinforcement bar. The spring member supports the back support frame such that the back support frame has an unstressed position and a reclined position. In the unstressed position, the generally horizontal portion of the back support frame is generally co-planar with the seat cushion frame. In the recline position, the generally vertical portion of the back support frame is moved rearwardly, and the generally horizontal portion of the back support frame is moved downwardly. The spring member biases the back support frame into the unstressed position. A seat cushion is supported by the seat cushion frame and the generally horizontal portion of the back support frame.

1. A stackable chair comprising;a base having a pair of generally parallel inverted U-shaped leg members spaced apart so as to define opposite sides of the base, each leg member including a front leg portion, a rear leg portion, and a generally horizontal portion interconnecting the front and rear leg portions, the base further having a generally horizontal seat cushion frame extending between and interconnecting the U-shaped leg members, the seat cushion frame including a transverse front spring reinforcement bar having one end interconnected with one of the leg members and the other end interconnected with the other of the leg members; a back support frame having a generally vertical portion with an upper and a lower end and a generally horizontal portion extending forwardly from the lower end, the generally horizontal portion including a transverse rear spring reinforcement bar extending side to side and disposed generally parallel to the transverse front spring reinforcement bar; a spring member having a first end interconnected with the front spring reinforcement bar and a second end interconnected with the rear spring reinforcement bar, the spring member supporting the back support frame such that the back support frame has an unstressed position wherein the generally horizontal portion of the back support frame is generally coplanar with the seat cushion frame and a reclined position wherein the generally vertical portion of the back support frame is moved rearwardly and the generally horizontal portion of the back support frame is moved downwardly, the spring member biasing the back support frame into the unstressed position; and a seat cushion, the seat cushion frame and the generally horizontal portion of the back support frame cooperating to support the seat cushion in a generally horizontal position.
