Abstract: A device is intended to make it easier for a person to arise from and/or sit down on a toilet bowl. The device comprises a first member being a part of the toilet bowl or attachable thereto, a second member adapted to carry a sitting surface-forming arrangement and which is vertically movable with respect to the first member, and a linkage defining the movability of the members with respect to each other so that the members are located close to or onto each other in a first relative position and spaced apart in a second relative position.
