ABSTRACT:
An adjustable armrest assembly includes an elongated connector and an armrest member which has a top armrest wall and two substantially parallel rail members on two opposite sides of the top armrest wall to slidably engage the elongated connector. A locking mechanism has a dog member which is connected to the rail members and which is engagable with the elongated connector for locking the armrest member against movement relative to the elongated connector after the armrest member is moved to a desired position relative to the elongated connector. A base is adapted to be fixed to a chair, and has a rotary shaft mounted thereon. A rotary seat is mounted rotatably on the rotary shaft and is connected to the elongated connector. A resilient engaging member resiliently protrudes upward from the base to selectively engage holes of the rotary seat for adjustably holding the rotary seat at a selected angular position relative to the base.
