Abstract: A self-leveling mechanism for an article mounted to a chair is disclosed. The chair has an arm member movable from a first position to a second position that is reclined with respect to the first position. The article has an upper surface having an angular relationship with respect to the support surface on which the chair rests. The mechanism includes a pivot member that mounts the article to the movable arm member of the chair. The movable arm member pivots with respect to the pivot member to keep the angular relationship between the support surface and an upper surface of the article the same without manual adjustment of the pivot member by a user when the movable arm member is moved from the first position to the second position. The mechanism can maintain items on a tablet mounted to the armrest during reclining action by keeping the tablet horizontal.
