Abstract:
An armrest assembly for a chair includes an armrest support, a mounting sleeve movably mounted on the armrest support, an armrest mounted on the mounting sleeve to move in concert with the mounting sleeve, and a lifting device mounted between the armrest support and the mounting sleeve and operable between a first position where the lifting device is locked to lock the mounting sleeve onto the armrest support and a second position where the lifting device is unlocked to unlock the mounting sleeve from the armrest support so that the mounting sleeve is movable relative to the armrest support freely. Thus, the mounting sleeve is movable relative to the armrest support so as to adjust the height of the armrest so that the height of the armrest is adjusted freely to support a user's arm comfortably.
