In one or more embodiments, a folding chair is provided having a frame, a seat operably connected to the frame, a backrest operably connected to the frame, and a counterbalance assembly, among other components. The backrest is configured to move between an upright position and a reclined position. The counterbalance assembly is configured to apply a counterbalance force to the backrest. In one or more arrangements, the counterbalance assembly is configured to provide a counterbalance force to move the backrest to the upright position in absence of an opposing force. In one or more arrangements the counterbalance assembly is configured to hold the backrest at one or more intermediate positions between the upright position and the reclined position. In one or more arrangements the counterbalance assembly is configured to increase the counterbalance force applied to the backrest at one or more intermediate positions between the upright and reclined positions.
