A chair comprises an elongated one-piece seat-and-back support bent so as to form a lower substantially U-shaped seat support and an upper substantially upright back support. The seat support includes lower and upper leg portions and a bight portion intermediate the same. The bight portion is resilient thereby enabling the upper leg portion to deflect downwardly relative to the lower leg portion, and the back support to move downwardly and rearwardly, in response to a downward force exerted on the upper leg portion. In addition, the chair comprises a stabilizer mounted between the upper and lower leg portions of the seat support and for providing stability to the same during downward relative deflection of the upper leg portion. The chair further comprises resilient stiffening member and a tension control mechanism. The stiffening member is mounted to and between the seat support upper and lower leg portions and functions to increase resistance to relative deflection of the upper leg portion. The tension control mechanism is movably mounted relative to the lower leg portion of the seat support for adjustable engagement with the stiffening member to adjust the same\s resistance to relative deflection of the seat support upper leg portion.
