With the intention of providing an arm-rest which can be readily adjusted vertically and laterally and intended, for instance, for a toilet o r lavatory seat, and which has but few movable parts, there is provided a positionally adjustable arm-rest which includes an arm-rest part and a frame-part, wherein one end (1) of the arm-support part is inserted together with two surrounding slide blocks (5) into the frame-part (3) such as to enable said arm-support part to be retained in its raised or lowered positio n. With the arm-rest in an essentially non-loaded state, the slide blocks (5) f ix the arm-rest in a horizontal position and hold the arm-rest in this position . The end of the arm-rest also includes a pressure surface (6) which acts against the inner surface of the frame-part so that the arm-rest will not give way when subjected to load. The user can readily adjust the position of the arm-rest. All that is required in this regard is for the user to grip the arm-rest part and swing it slightly upwards while moving the same to the position desired. When the end of the arm-rest has been moved to the height desired, the arm-rest part is released and swung back. The arm-rest part is now fixed in position and can be subjected to load, by virtue of the pressure surface on said end of the arm-rest. Lateral adjustment of the arm-rest is achieved by virtue of the frame-part (3) resting on a rotatably adjustable floor plate (16), or being rotatably mounted to a wall structure.
