The locking device is for a rocking chair. It has a stationary lower frame a nd an upper frame rockingly connected thereto, including a notched member fixed to the lower frame, and a lever assembly mounted to the upper frame, and including a lever arm pivoting about a support in response to a user sitting on the se at area, a spring urging a second end of the lever arm to engage with the notch ed member to lock the device when the user disengages the seat area, the second end disengaging when the user sits up. In a variant, the locking device includes a friction band mounted to the lower frame and a cam rotatably mounted to th e upper frame, the cam being rotatable by a handle to thus engage the friction band and lock the upper to the lower frame.
